WHAA??? I just saw this. Awesome bro!
I look forward to your component, but think I can work with this with the input sliders! lol
Got some days coming up it’ll be quiet around the house & I’ll have some time to get started with this. I can hardly wait.
Thank you!
It’s the script we worked out last year. Just a basic python script that in general is quite reliable but maybe less than half a dozen times has hung for reasons I’m not quite sure. Restarting the pi zero has fixed it every time.
I’m not home now so I can’t access the actual script but it is based on this script:
import time
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
temp_sensor1 = '/sys/bus/w1/devices/28-#######/w1_slave'
temp_sensor2 = '/sys/bus/w1/devices/28-#######/w1_slave'
def temp_raw1():
f = open(temp_sensor1, 'r')
lines = f.readlines()
f.close()
return lines
def temp_raw2():
f = open(temp_sensor2, 'r')
lines = f.readlines()
f.close()
return lines
def read_temp1():
lines = temp_raw1()
while lines[0].strip()[-3:] != 'YES':
time.sleep(0.2)
lines = temp_raw1()
temp_output1 = lines[1].find('t=')
if temp_output1 != -1:
temp_string1 = lines[1].strip()[temp_output1+2:]
temp_c = float(temp_string1) / 1000.0
temp_f = temp_c * 9.0 / 5.0 + 32.0
return temp_c, temp_f
def read_temp2():
lines = temp_raw2()
while lines[0].strip()[-3:] != 'YES':
time.sleep(0.2)
lines = temp_raw2()
temp_output2 = lines[1].find('t=')
if temp_output2 != -1:
temp_string2 = lines[1].strip()[temp_output2+2:]
temp_c = float(temp_string2) / 1000.0
temp_f = temp_c * 9.0 / 5.0 + 32.0
return temp_c, temp_f
while True:
print(read_temp1())
print(read_temp2())
time.sleep(1)
Then there is another script which publishes to MQTT. I have to imagine it’s likely the MQTT script which is causing the problem because when I catch the problem I notice my temp graph in HA will say last updated hours ago. If it was a problem with the temperature script the temperature would likely come back as an error. I don’t know how to verify I am correct on that though.
I’ve got some basics of a component built now, very early work in progress.
I’ve also been using a custom UI component for it https://github.com/thomasloven/lovelace-slider-entity-row
Need to pull it all together and build something proper that can be contributed back to HA but for the moment this will get you a slider for each color channel, as is. If you add a light called “DT light” it will give you 7 entities called light.dt_light_uv, light.dt_light_violet…etc.

elif brightness > 0:

self._brightness = (brightness / 100) * 255
Caveats right now are:
no support for turning on/off schedule (you need to manually do that before using this, or else it will just flash the color change)
no support for setting more than one channel at once. I think I need to add a service to handle this scenario but I need to do more reading. This is useful for adding automatons for colours, getting it to go to all blues or all whites on command for instance.
no support for HD (ie. over 100%) yet. For safety I’m limiting all channels to 100% until I work out how to build the client side validation that would be needed to support this. The python module already has this safety build in though.
Ciwan - okay, post the actual script when you get home and have time. No rush, I’m heading to bed in just a bit. It’s 2:26am here. 
Ok here is my mqtt script
#!/bin/bash
until [ "$?" != "0" ];
do
#individual temp probe and mqtt commands here
mosquitto_pub -u myuser -P password -t homeassistant/sensor/fishroom/temp5_F -m "`/home/pi/temp5_F.py`" -h myipaddress
# Sleep in seconds
sleep 55
done
I changed my -u and -P and the ip but the script works
and here is the temp script:
#!/usr/bin/python
import os
import glob
import time
os.system('modprobe w1-gpio')
os.system('modprobe w1-therm')
base_dir = '/sys/bus/w1/devices/'

device_file = device_folder + '/w1_slave'
def read_temp_raw():
f = open(device_file, 'r')
lines = f.readlines()
f.close()
return lines
def read_temp():
Sorry it took me so long to finally get these. I pretty much forgot how to SSH into my pi and had to get a new router so it forced me to actually do it.
I can’t remember who was talking about Seneye on this thread but I wrote a custom component to support directly plugging your Seneye into your RPi and get the data via a native python driver that I wrote as well. Figured I’d add a link to this thread.
There is still the nagging question of does the device store results locally or not. From my reading/testing it seems like if you leave it in interactive mode (“HELLOSUD”) then it doesn’t cache local results and fill up. I guess further testing will reveal that. I’ll figure out a way around that if I have to.
Fun thread! Very inspiring. We keep a 30 tank goldfish breeding room, so obviously aquarium threads are very intriguing. I’ve just recently found Home Assistant and am almost happy with our basic setup for the house, but I’d love to eventually do more with the fish room. We have lights and our central water change system on there, but very little in the way of monitoring besides a motion sensor for room temp/turning on the lights and a few leak detectors. I have a ton of Arduino stuff I never really got into because it was over my head at the time, but this is making me want to dig it out again
Hi all,
wow to begin with. This thread answered questions i had
I’m doin some small time breeding too, fresh water.
Have lights and temperature in HA at the moment. Using Fibaro universal sensor for temperature.
Have thought about ph and other values and after reading this thread i will start looking at this again
Thanks
I will be lurking 
Welcome to the thread @aktill & @sabbath.
I hope it’s useful for you both & please feel free to share your journey’s and experiences with the rest of us. We’re all learning together. I sometimes go quiet because other day job work keeps me busy but I still lurk & follow up what others are doing and contributing.
BTW, if there’s anyone in this thread who’s in the Netherlands / Germany / Belgium / UK & can make it to Hack in the Box Amsterdam HaxPo on May 9 & 10th, I’ll be there hosting the Wireless Hacking Village - come on over (it’s free to the public, you just have to register before hand on the website) and let’s meet face to face!
Just a status update - I’m one year and 10 months into using Home Assistant for total system control and management of 8 aquariums at the moment & loving it still. I stopped with breeding clownfish after a successful run…too successful, still trying to sell off the last babies from last year. But the flexibility of Home Assistant to scale up and down economically (approx 300-350 euros vs. approx 15,000 euros for a multiple redundant Apex controller setup) is a serious boon and win.
I finally got around to setting up TTS Voice & Sound Effect Alerts last year, which is super nice on several levels. My primary controller actually sits upstairs, away from the tanks & on a completely different circuit breaker than the aquariums downstairs & pushes TTS Voice messages over MQTT to the Remote HA Pi’s downstairs & on every floor. That way I only have to change / add the TTS voice alerts on a single HA instance, rather than duplicating on every Remote Pi that has a speaker attached to it. I have alerts for Kalkwasser / Top Up problems, Tank Overflow Alerts, Status Alerts during the wholly automated Water Change Processes (cause that sometimes caused an alarm with the wife, when she didn’t know before hand I was running one. lol), as well as voice prompts for home automation & security. Just try to get an APEX or competing aquarium controller to do all that. 
Enjoy!
Thanks! Been learning a lot.
In terms of voice alerts I just leverage our Alexas. I can call any of them directly with TTS, and so for water change fills I have a series of notifications that go out (tank filling, tank full, tank drained). I don’t have ours completely automated because I don’t trust auto dosing of Seachem Safe, so that’s a manual step. I then turn on the change pump by voice, and it lets me know when the tank is drained (we change daily from a 150 gallon holding tank).
I also have the intention of voice alerting based off some Smartthings leak sensors (duck weed causes the odd issue), but I don’t want to buy a ST hub and I haven’t quite figured out Conbee/ST playing nice yet.
I did recently figure out how to make our Fluval 3.0’s play nicely with a timer, so I can get a few ramp on/off periods over the day (that’s sort of nice).
Otherwise, just a lot of wet sleeves keeping all the babies fed and happy.
Before I found home assistant I was working on an Alexa custom skill to allow me to use voice to log all the things I do around the fish room (dose ferts, change water, start and end quarantine etc). It’s a big job, but it was coming along slowly and steadily.
After finding HA, I of course wanted to start displaying those results graphically in my floor plan layouts. Ideally, I’d have visual alerts when I filter was due for cleaning etc (with 30 tanks, they aren’t getting done each week).
Think I’ve finally cracked how to read my DynamoDB in Node Red, so now it’s just a case of figuring out how I want to show things in the floor plan. Gets a little squinty, so still a work in progress.
On other fronts, I just bought a Nest temperature sensor which I can’t seem to read in HA, and my SmartThings water leak sensors are becoming a PIA. I was hoping to read them with ZHA and a Conbee stick (not supported in Deconz), but I don’t quite yet understand how to read them (work in progress).
I’ve also decided to at some point hook a spare Arduino I have up to HA in some fashion (to drive some fish room tank temp and level sensors), but that’s a whole kettle of fish in terms of communicating with my wifi HA Pi etc.
Making progress though!
Dude! I finally had some free time to try the pyseneye & Seneye component you made for us. Awesome! Now I just have to order some new slides. Thank you!
Also, back when I setup my Seneye through the API interface, I made my own icons for pH, NH3, O2, NH4, and light values. (see screenshots) Dunno if there’s a way for you to include them as part of your component but I’m happy to contribute them to the HA component. Just tell me where to send / upload them.
Well done!
Glad to see someone else is getting some use out of it
Great icons! I think the best way to get them included is to contribute them back Material Design Icons, then I can change to using them once they’re accepted there. https://materialdesignicons.com/contribute
I found this may interesting for finding NH4 value from dissolved NH3
@cowboy I’ve released a more complete version of my AquaIllumination component. Finally did a write up on it as well. Figured I’d add a link back here as well, since this is pretty much definitive aquarium thread.
Hi,
I have been following your project for quite a long time just reading through and through trying to see how i can put it into my use as i don’t own a aquarium but i do hobby hydroponics and the hobby has gone quite a big now changing water from tanks and dosing plants is just a head ache so for nothing is problem running dosing pumps on 12v with input slider as how long it will run the relay the pump is plugged into seconds it runs so its 1ml per second setting achieved by putting a speed controller in between the pumps and controlling their pumping speed till i got to my 1ml/sec.
Please i would like your and the community help into i want to integrate pH, EC dissolved sensors and i am not a coder or anything but i follow any guide and tweak things like anything please if any one can point me this direction how can connect Ph and ec sensors to HAssio it will be a great help into next direction
thanks in advance.
Hi Gagan,
As far as doser pumps, I’ve already done a write up on how to convert 220V Stepper motors for doser pumps into HA controllable, removing the need for the older micro controller they previously were provided with. I also provided the code I threw together to provide the User Interface elements & MQTT side of the solution.
This solution should even work with DC powered motors either with the DC version of the Sonoff 4-gang switch or if you build it from the ground up, 3D printing the dosing components and supplying only ESP chips and motors, and wiring it together yourself.
Of further interest to you, I’ve adapted two 4 channel dosers this way, and One has been installed on the aquarium with great success. The second unit had nothing to do since I stopped with breeding clownfish, so now it waters the backyard flower garden for my wife. I even introduced a binary sensor to indicate when it’s raining, that it doesn’t need to water the flower garden on that day.
Unfortunately, I’ve not had any time or hard requirement to implement EC or pH Tube sensors. My salinity stays pretty solid in place, and pH is measured by the Seneye devices I have. (Bows in appreciation to @mcclown for making this possible.)
I do know that making the hardware for pH meters is esp difficult due to electrical isolation requirements needed for an accurate pH measurement. There are some links to some 3rd party solutions that are prebuilt and made for makers, which are above (I posted about a year back about this topic) which I would recommend you to look at. But perhaps someone else on the forum has made their own pH / EC solutions and has good plans for it and will chime in to help you.
Good luck and keep us posted what you end up finding to go with, so that other’s may also learn from your experiences. 
Hi,
thank you for taking the time out and replying, i have had full luck with all the automations from drain pumps (relays with level float sensor) to fill pumps(relays with level float sensor) even putting in flow sensors to calculate amount of water flowing in and out of the tanks.
Again the relays control all the important functions like lights fans heater chiller humidifier connected with corresponding automations.
the problem when i get stuck with is again pH and EC i am even ready to spend for tentacle shield and stamps by atlas scientific but then again i am no coder i need something which tells me how to connect, will go over again with your recommendations.
i have scoped now the tentacle shield and the example library is pretty easy to code on arduino and run any idea how we can get feed from sensor connected to UNO on I2C to hassio ?
Thankyou again
I would urge you to check out reef-pi - there is a tutorial on how to integrate the atlas scientific pH probe. The info from Reef-Pi is then available via API, which can be easily pulled into HomeAssistant as a sensor. Even if you only use it for getting pH readings, it will be by far the easiest way to grab that data, as you won’t really have to muck about with code.
You can also look through the giant Reef2Reef thread to see how other folks are getting pH readings with it.
The Atlas probe is too pricey for my little nano setup so I’ve just integrated a Google spreadsheet where I update dropper tests. You can read more about my setup on my Reef2Reef thread, which is a mixture of Reef-Pi and HomeAssistant control.
Just for kicks, here’s what mine looks like lately:
Thank you , for the link to reefpi going to check this out also had a email conversation with atlas scientific they say they are currently working on the code for mqtt as almost everyday they are getting requests the guy said almost 2 weeks and it will be done. so looking forward for that also,
can you also share how you used API settings from reefpi to HASS your system seems to reporting all the values needed
many thanks
