Hi
I have been looking at ways to control my under floor heating system through HA. I have two manifolds next to each other, each connected to 8 heating loops. So in total there are 16 loops controlling about 12 zones.
I will have Xiaomi temperature sensors that report the temperature of every zone to HA. I then need to find a way to control the motoric valves.
First I looked at ready solutions like Homematic IP but found that too expensive.
Next I researched arduino boards and ways to open and close the valves using ESP32/8266 and relay boards but I’m just starting tipping my toes into the home automation world so I’m afraid that is going to be too complex (I am an engineer with some programming background).
Now I am wondering if it is possible to use the Sonoff 4 Channel R2 switch or the Shelly 4 Pro. I would then connect 4 and 4 valves to each switch, which means I would end up with 3 or 4 switches. Then I would let HA tell the switches when to send power to the valves depending on the output from the temperature sensors.
So I ask you, is this solution the easiest “cheap” way to accomplish my goal or am I overlooking something?
And if I decide to go with e.g. the Sonoff 4 channel switch, do I need to flash it with Tasmota and use ESPHome or can I just use it straight out of the box?Thanks in advance
