Fibaro Radiator Heat Controller with external thermostat (e.g. Nest)

[kristofre 1]

Hi,

 

I am looking at buying a couple of Fibaro Heat Controllers to remotely control my radiators and create schedules.

I wanted to know how this would work in conjunction with an external thermostat such as a Nest.

I use the Nest to control my boiler, regardless of the availability of the official Fibaro plugin for Nest (while we are on the subject: what is happening with that).

 

So my question: If I use the Nest to control my boiler and it has switched itself off, does it matter  if the Fibaro Heat Controllers are still "On"?

With a regular valve this does not matter but I was wondering if there is something particular here.

 

Thanks in advance for your feedback!

 

KR,

Kristof

 

And PS: Nest plugin!!!

Hi guys!

 

If this Nest thermostat is not a Z-Wave device, and you don't have any schedules made on HC.

 

Our Fibaro Heat Controller will be limited similarly to a regular valve.

Unless, of course, Fibaro pulls their socks up and does a proper integration with the Nest so it can be part of the heating panel :-).

 

Also, how does the Fibaro Heat Controller control a boiler?

AFAIK they only control a radiator. In which case if your thermostat activates the boiler because it is too cold but in Fibaro the Heat Controller is not on, couldn't you potentially be having the boiler working at 100% without effect?

Awesome!

Nothing beats "official" support in this but as always the community can do better

Thanks for sharing!

Either use a script or remove the room thermostat. Works better without room thermostat. What? Peter says to remove the room thermostat? Yes I do say so...

Hi Peter,

 

Interesting post!

Not sure if I would apply it though. My use case is more the following: living room has to be always warm and at certain points other rooms would have to be heated as well (or not) like the bathroom, home office, ...

Out of curiosity: I have a Vaillant EceTec Plus 295, would your mentioned technique work?

 

Thanks for your reply in advance!

Yes, my explanation applies to your case as well. You can save some money by installing older, mechanical TRVs in your living room, if you are sure you do not want any schedule on them. Then your HA system only controls the other rooms... Electronic valves are more accurate, but mechanical valves are indestructible and do not use batteries...

I'd say, generally speaking if your heating system already uses TRVs, it is OK. If not, please check with your installer. For the configuration of your system, you'll also have to check with your installer or check the "advanced" or "installer" manual. Not all companies give these manuals to end-users though... Maybe someone else here can tell you the specifics (on how to disable your room thermostat, set the temperature, add an external sensor, ...).
