Hi there,
i’m was searching for a nice device for managing a group of fancoils over a dry contact.
I have seen multiple “tuya” zigbee devices like this that are compatible with zigbee2mqtt.

The feauters that makes me interested in them are:

  • No battery
  • Integrated themometer (with no battery!!)
  • a dry contact (to use for example with a contactor)
  • mesh routing capabilities as they are powered devices

But i still can’t understand if they can be used in both heat/cool mode as on zigbee2mqtt support page there’s only a reference to the fact that it expose climate entity and i’m worried they are exposed to just “heat” mode.

Any experience with these kind of devices? Can you help me in search of alternatives?

None.

But my guess would be that it the device in question only has a single dry contact it probably only supports a single function (heat or cool) it may be re-configurable to control either a heater or an AC unit - but I doubt you can control two functions without 2 contacts.

My guess was the same but i just need a single dry contact for both function.
It has just the purpose of removing ac power from the fan coil’s line.
