Hi!

I plan to use thermostat to control 6kW 400V heater in a water tank.

My plan is to use 24V DC external power supply, connect it through relay on the board and steer contactor like this: https://epstryk.pl/product-pol-25682-St ... Hager.html to which heater will be connected.

Do I need to protect the board additionally or will Relay Shield WEMOS D1 suffice itself?

Hi,
I have a little problem. While using the thermostat I get some strange readings of 85C every period of time. Sometimes it appears on the screen too but it is mostly visible on the app (attachment1). I' ve read that it may happen due to time between measure start and read (from 900ms change to some bigger time) . Did someone managed to fix it or know how to do it and have a .bin for it ?

I would like also to ask did someone used ESP with external antena for this project?

Thanks for help

PS. Will the system for offline?

reading 85º is a known problem, it is due to poor quality Chinese clone DS18b20.

What version of the soft are you using?

I still working on making Arduino IDE work with my ESP but still get multiple errors with compilation error for D1 mini , so I just uploaded ready .bin file into ESP by esptool
