Hi all,
Currently I am using the built-in thermostat function of home assistant, with a shelly relais to enable a heater, and a Shelly H&t temperature sensor.
The shelly h&t is usb powered, but is measuring too slow. Apparently it is programmed too wake up as little as possible, because wifi transmission heat up the chip and influence the measurement.
I’ve set the treshold to 0.5° but it is not fast enough for accurate temperature control.
Now because at work I have an Omron Ethernet temperature controller that does modbus, I’ve tried that controller, to just read out a PT100 sensor via ModbusTCP every 5s. (no controlling with the omron, control remains in ha).
So using the omron temperature input instead of the shelly temperature sensor, the temperature control is much better!
So I am looking for a (preferably wired) ethernet temperature sensor that does ModbusTCP.
And not as expensive as the industrial one that I am using.
Any suggestions?
Thomas.
