Thermostat - built in humidity control

Anything out there yet? Z-wave or zigebee?

The Ecobee 4 and the new smart version can do this.

I have an Ecobee. I want to step away from cloud based products.

Every ecobee, going all the way back to the original "ecobee Smart" thermostat has the capacity to dehumidify using "AC overcool".

I haven't seen any other thermostat with that function built in. With the z-wave thermostat and humidity sensors, it should be possible to run a Rule Machine automation to achieve the same effect.

Not to my knowledge. But if you humidity sensors paired to HE, it should be possible to create a rule that decreases the thermostat set point when humidity increases beyond a specified level. And then reset the thermostat set point when the desired humidity level is reached.

That's the route I would take as well, pick up an NYCE, then you get motion and temp for free...

That’s not what I’m looking for.

I have a central humidifier. It’s attached via a wire to the ecobee that controls humidity in the winter.

That’s what I want out of a zwave thermostat

I knew what you meant and was about to reply as I have the same setup. Thinking out loud you could just get any zwave stat and then use a relay to control your humidifier when the stat is in heat mode and humidity is at certain level. All it needs is 24 VAC and any relay could do it.

I misunderstood you. I think the Radio Thermostat CT80 has humidifier/dehumidifier terminals.

Thanks.

This looks promising. It also has the de-humidifier with AC like the ecobee.

At least the manual states it.

I wonder if there is a driver for it.

I don't know. I do know you can get it with a WiFi or zwave module. The zwave module doesn't allow for (de)humidifier control by generic zwave thermostat driver.

The wifi module supports local control, and Radio Thermostat have a published local access API. So it should be possible to write a local-control driver for it, if one didn't exist.
