Anyone been using Mi Flora sensor? Worth it?

anyone can tell me why my log fills with this stuff and what to do against it.

Sorry for the late reply but here is the list of parts and a link to go with each to purchase. I ended up modifying a few things and switched to a 6 zone and added in buttons to manually water individual zones. So what I have is 2 nodemcu, one controls the button configuration and the other nodemcu controls the relays that would power on/off the irrigation valves.
The nodemcu that controls the relays is running tasmota and is fairly straightforward on how that is setup. I just soldered a jumper wire to each of the NO contact on the back of the relay board that way I just had to bring the power in on the first NO and then the rest would have the power. Also by doing it that way it made it for a nicer/cleaner look to just having to plug in the valve wire go in according to zone/relay #'s.
I choose to use terminal blocks to help keep nice and clean as I knew it would get messy with the amount of wires going in.
So I have a 24vac sprinkler transformer power going to NO contact on relays for valve control, then I took that same ac power to a Altronix AL624 Proprietary Power Supply to convert that to DC to power the nodemcu’s.
I also have a sonoff basic to control the main irrigation pump. That is also running tasmota.
The nodemcu that is controlling the buttons is using a sketch I put together and is up on my github.

Thanks for the info. That led me to this 8ch module with USB and what looks like an AVR on it.
The possible AVR has a header next to it. I’m wondering if I/we can reflash the AVR with Arduino code to then accept serial from NodeMCU or ESP8266 module mounted to the back of it and use this module to expand and drive the 8 relays. If so, it’s a two module watering system solution for under $15US…

mr.sneezy · October 23, 2018, 6:53am

I’m going to drop two other 8 channel relay board suggestions here for comment.
The first is a complete system controlled by Bluetooth for about $20US. Now I know little about bluetooth via HA so any comment welcome about how easy or hard getting HA on Raspberry Pi 3 BT to control this module ?
The second 8 channel module is controlled by Modbus serial. While this would need a serial interface to my HA Pi it might be easier than the above as HA seems to have a Modbus control component. Again any useful comment accepted as this is a third possible option now.
Due to the cheap price and fairly complete nature of these modules it is going to be economic enough to buy two, so to have a spare to swap out (which is important in a hot Australian summer…).

Anyone using my garden irrigation system (I know there at least a couple of you from messages I have received) might want to look at this thread.

mr.sneezy · October 30, 2018, 10:45am

A very neat way to do an eight station controller. One board that’s it !

ulises3131 · October 31, 2018, 10:09pm

i got too errors in log since 0.81.1
after modifying:
{{(float (duration) * 60) | round}}
by
{{duration | float | multiply (60) | round}}

I still have many mistakes

Help!, please

Thanks
**sorry for my bad English

klogg · October 31, 2018, 10:18pm

Yes, I was about to post here about this…

Check this thread. A template question after 0.81 upgrade

There was a big change in 0.81 that affected template sensors. The change also highlight that I wasn’t setting them up the best way

The changes needed aren’t big, read the thread and hopefully you can work it out. Post here if not and I will try to help you.

Here’s my (pretty simple and fun) apartment and rental friendly irrigation system. Main hardware is a cheap USB pump off Ebay, a smart switch (xiaomi), some Mi Flora sensors, and a xiaomi water sensor (which is not operational at this point).

rowdy15 · November 20, 2018, 10:16am

Hey All,

Got into HASS about a year now and slowly building up my smart home. Spent a bit of time making my own irrigation project. I really appreciate the code petr has provided, wish I had of seen it earlier, but will probably integrate a couple of pieces of code into my setup at some point.

I have done mine slightly differently, possibly made more work for myself in doing it the way I did. E.g. using a microcontroller board with two microcontrollers, multiple flow meters, fet relay board, moisture sensors.

But it works for me at least.

All the code is in my github repository.

marksev1 · November 30, 2018, 11:29am

So does the online weather adjustment work now?

hhaim · March 17, 2019, 7:31am

I’ve created a component to estimate the time to irrigate. The model is taken from leaky bucket model from networking

component is here:
https://github.com/hhaim/hass/blob/master/custom_components/wb_irrigation/init.py

This is how you use add it

wb_irrigation:
  api_key: !secret openweathermap_key
  rain_factor: 120
  max_ev: 3750 
  min_ev: -1500.0
  name: "wb_irrigation"
  longitude: !secret accurate_longitude
  latitude: !secret accurate_latitude
  taps: 
    - name: p1
    - name: p2

iz3man · March 17, 2019, 6:48pm

@hhaim: I’m not aware how to install extra components. Could you please give a short instruction how to do it? Any how does it work together with the “other” component? Do you add some automation asking your sensor for a special condition?
Sorry for noob question - I’m just a user

hhaim · March 17, 2019, 7:06pm

You can read in the following link how to install

This is not a full solution yet, just the complex part to add sensors that will estimate the irrigation time per pipe base on actual weather conditions. I will add the automation block soon (simple)

hhaim · March 23, 2019, 10:27pm

Hi iz3man

I’ve updated the automation you can look into the code again (in my case two taps)

The ingredients

Sonoff 4ch pro (up to 4 taps) + Tasmota
Appdaemon + hass

hass configuration:


wb_irrigation:
  api_key: !secret openweathermap_key
  rain_factor: 120
  max_ev: 3750 
  min_ev: -1500.0
  name: "wb_irrigation"
  longitude: !secret accurate_longitude
  latitude: !secret accurate_latitude
  taps: 
    - name: p1
    - name: p2

Create sensors wb_irrigation_p1 and wb_irrigation_p2 that will calculate the time to irrigate based on ev/rain
The units are ev (~100 for a cold day and ~300 for a very hot day). Rain will add factor* total_mm (ev) to the queue

The full configuration is here (with switch for tasmota and some sensors)

github.com

hhaim/hass/blob/master/pkgs/irrigation.yaml


homeassistant:
  customize:
    switch.wbi_p1:
      friendly_name: p1
      icon: mdi:water-pump

    switch.wbi_p2:
      friendly_name: p2
      icon: mdi:water-pump
    

# sensors for weather based irrigation 
# calculation factors based on rain and evaporation model
wb_irrigation:
  api_key: !secret openweathermap_key
  rain_factor: 90
  max_ev: 3000 
  min_ev: -1500.0

iz3man · March 24, 2019, 3:20pm

Thanks! That looks great. I’ll try to implement that and will report back.

iz3man · March 24, 2019, 5:15pm

@hhaim: What’s platform: accumulator ?

hhaim · March 24, 2019, 5:49pm

It is another custom component to accumulate time (week/month) faster without database query. In this case the total time each tap is open.

It is not mandatory

iz3man · March 24, 2019, 7:02pm

Thanks. Could you please tell me where to get it? Googled it, but it doesn’t give any results.
