Multi room heating with Nest


#1

Hi,

At the moment I have a Nest in my living room, but I would like to upgrade so that I can heat each room separately.
My heating system uses 2 collectors (ground floor and first floor) where it is possible to put valves on each output.
What valves and controller best works with Homey? Or is there a better solution?
Is it possible to combine this with the Nest I already have installed?

Regards

Anyone with any info?

I have just installed the Plugwise HA zone heating system at home. http://www.plugwise.com/en_US/
I do like the main statement on Plugwise’s website, in relation to your question: " Het komt uit een goed nest"

Still experimenting with it, but working as it should.

You could still use the Nest as room thermostat (but it’s smart options will be disabled).

Thx. I’ve been looking at Plugwise, but I think that in my setup (with Nest) I also need an Adam. But there is no app for Homey that supports Adam. Or would I not need to control it directly?

Hi @Davy_Vissers,

If you want multi room heating, where the heater is switched on / modulated based on the heat demand out of the individual rooms, you’ll need to install the Adam module (in between Nest and the heating system).

The current Plugwise app does not support the Adam; partial control can be gained by using the Anna driver.
I’m currently checking with Plugwise the options to get Adam supported.

I asked this question at Plugwise and they said that Nest doesn’t give info, via Opentherm, about current and set temperature. And that it doesn’t support ‘overrides’ via Opentherm.

Also the heating system has to support Opentherm, which mine doesn’t.
