How to read the control signal 0-10v

Post by mozmo »

Hi. I would like to see if / when the valve for my heating system opens and how much in Domoticz.

The valve is this:

Temperature regulator is this:

How can I get the control signal into Domoticz?
I have z-wave and rfxtrx 433mhz.
What can I use, and how do I connect?

Hi,

Did you ever work with some electronics? If you would use an esp8266 (Wemos D1 mini e.g.) and espeasy, you might feed the signal through a voltage divider (2 resistors) to the analog input (so to change the 10v back to I think 3.3v max, but you would need to check the specs of the esp8266 analogue input). I'm no electronics engineer, but that should not be too difficult I think. The espeasy is then connected through wifi to Domiticz.

Regards,
Marco

Hi,

Just check the type of board you have, as ESP8266 max analog input voltage is 1V only, but some PCB already have some embedded dividers to match other voltage (3.3V for D1 mini).
