Hi Kajmaj,
Is it not possible with the hf2211 to connect the hydrolife equipment to the internet to be able to register in the vistapool cloud? First I wanted to test how it works in the cloud and what parameters it gives me … then I wanted to integrate it into HA.
Why is it not possible to activate the internet menu in Hidrolife?
Can you also indicate the connections of the Hidrolife equipment as it is connected … VCC, GND, TD, RD?
Thank you very much in advance.
Regards,
@Josser, it is possible to have Hidrolife connected to cloud if you have vistapool wifi module.
Wifi module is connected to the same internal databus as HF2211, they can be connected in parallel (two connectors are available)
With wifi module you have info/control on pH, temperature, filtration timers, pool light, HVAC control eventually, etc., depending on your options.
If you decides to use MODBUS write - Hydrolife must be in manual state, othervise external MODBUS commands does not work properly, data reading works fine everytime.
Q: Why is it not possible to activate the internet menu in Hidrolife?
A: You must have wifi module and activate it in the vistapool service menu
Q: Can you also indicate the connections of the Hidrolife equipment as it is connected … VCC, GND, TD, RD?
A: Do not understand what you are asking for. 
What you’ve marked is dedicated for Vistapool wifi module.
I have the HF2211 connected to the next on the right and pins 2/3 are used for modbus data (A,B)
I did not try to connect 1/4 from Hydrolife to 1/4 of HF2211 (to power HF) not sure if Hydrolife has sufficient power capacity, it might work or it might burn hydrolife.
I use external pover unit to power HF2211.
Ok, thanks you for information.
Hi Thomas,
You know if the hf2211 module can help communicate with vistapool. I need to connect the hf2211 to the Hydrolife team and connect to the cloud.
Regards,
@Josser If I understood well, you don¨t have the Vistapool wifi module.
In general, there are 3 ways how to operate Vistapool Hydrolife.
My conclusion
Hi kajmaj,
ok, now i have it clearer.
Excuse my ignorance. We will try to connect by modbus and I will tell you the result.
Thank you.

Hello there. Thank you for your work on this. I just installed a Vistapool wifi module on my Hayward AquaRite+ controller & chlorinator. It pops up OK in the Vistapool website and I can control it there. But when I add and configure the HACS integration, I don’t see any devices or entities. What should happen after I add the integration?
Would you mind posting the Vistapool document with the modbus details again?
If you want to use Vistapool wifi module you do not need modbus. If you want to use modbus, there is no need to use Vistapool wifi module.
Hi everyone,
Appologies to reply to and older thread. Since the last vistapool update earlier this week, pulling the JSON values from the public vistapool site seems impossible now.
So I’ve decided to try Kajmaj’s approach, and use a HF2211 module in order to get all values through MODBUS.
I followed the wiring example in this thread (pin 2 and 3), but basically, I tried all the pins just to be sure (except pin 1 of course: power).
However, I cannot pull any data from the device when connecting to port 23.
I’ve tried to use any register in this thread (dec and hex) using qModMaster, a tool which I used before with other MODBUS devices, but no luck, I cannot get any data from the HF2211.
Does anyone have any recommendations or ideas please?
thanks in advance
Fixed my own issue using an RS485 USB adapter (ch341) + Raspberry Pi.
@steegy I am also a “victim” of the vistapool update.
Connecting the hidrolife directly with the Raspberry Pi sounds like the perfect solution for me.
So you used the mentioned RS485 USB adapter (ch341) together with the Raspberry Pi without the HF2211?
How did you connected the RS485 USB adapter (ch341) to the hidrolife?
And could you maybe share a link / picture of the RS485 USB adapter (ch341) you are using?
Thanks you 
@ DIeHarke Sure,
Here’s what I did.
I have a Raspberry Pi3 with raspbian installed close to my sugar valley computer.
I already used this Pi to share an RFXCOM controller with my domoticz server using ser2net.
(basically to share a USB module over ethernet)
In order to read the sugar valley’s modbus data, I bought this USB adapter from aliexpress (ch341).
FYI, I only want to read MODBUS data, not write it.
Use the “extern” RS485 connector on the sugar valley computer (right side).
On this connector you need PIN 3 and 4.
PIN 3 = white wire
PIN 4 = red wire
PIN3-white goes to ch341 PIN A
PIN4-red goes to ch341 PIN B
Connect the ch341 to the Pi, and install mbpoll
wget -O- http://www.piduino.org/piduino-key.asc | sudo apt-key add -
echo 'deb http://raspbian.piduino.org stretch piduino' | sudo tee /etc/apt/sources.list.d/piduino.list
sudo apt update
sudo apt install mbpoll
Find the USB ID using “dmesg | grep tty”
Use mbpoll to read a few registers, in order to test connectivity:
mbpoll -m rtu -b 19200 -t 4 -r 256 /dev/ttyUSB1 -P none -1 -c 31 -q -0
In this example, I read register 256 + the next 31 registers.
-0 is important here, because sugar valley starts with register 0, not register 1 like most devices do.
Then I created this script to import only the values I need, to pre-created domoticz sensors.
(I know my scripting skills are limited, but they do what I need so far 
)
mbpoll -m rtu -b 19200 -t 4 -r 100 /dev/ttyUSB1 -P none -1 -c 31 -q -0 > /steegy/vistapool-modbusrtu-domot3/poll-part1

In case you want to add additional registers, you can get the register numbers from the sugar valley modbus PDF manual, just remeber to translate HEX to decimal first.
But in my case, these are the most important registers I need, in order to get my winter-anti-freeze protection automation up and running, which is automated through domoticz.
My first attempt was to share the ch341 USB adapter using ser2net, with my domoticz server, but this was unsuccessful, so I decided to have the Pi run the mbpoll script (or optinally, you can call the mbpoll export though SSH)
FYI, to explain the “-z $flowsv” routine:
I have about a 1/100 chance that a modbus read fails, in case it does, and my variables are empty, I want to prevent the script to update my domoticz sensors, and wait untill the next successful run to update the sensor.
@steegy Thank you very much for your detailed explanation. This helps me a lot to get into the topic MODBUS. And I hope for many others as well for all that effort you have put in writing this.
In case the new API access gets delayed or blocked, does anybody know if the same modbus approach can be done by using a UART to WiFi module like this one? The same module is used by the Visonic Alarm component in HA and works great. Any help reading values just for temp, pH, Rx and filtration on/off? Thanks.
I’m trying to access by Modbus with a HF5111B module. Can someone share a working config in HA and the correct settings in the module? I keep getting
Pymodbus: Modbus Error: [Input/Output] Modbus Error: [Invalid Message] No response received, expected at least 8 bytes (0 received)
Is there something that needs to be activated in the Hydrolife unit for the EXTERN modbus connector to work? Thanks.
I found a solution with a ESP8266 and Tasmota firmware, works super. And cheap…
