    I am currently wiring my house and we're on the lighting circuits now. As I have a "brown field" site, I can do what I like.

    Hi,

    Sure. Fibaro Lite is cheap enough and seems extremely reliable. It's been running for a couple of months with no hiccups.

    The programming is GUI style block-logic so is limited. However it...

    Personally I prefer to have direct access to my HA systems (I have a /27 pool of public IPs so no need for NAT, port forwarding and all that broken nonsense).

    OK - it is only that I'm sure HG claim somewhere you can manually adjust the Danfoss rad valves.

    Well, yes you can, but it's only meaningful if that gets flagged up to the controller.

    The Danfoss Zwave TRVs do not have a published ZWave packet for "calling for heat" from the boiler.

    Thanks for the reply - sounds like you are pleased with the system.

    I did not know the StellaZ's were simplex - I assumed they could at least manage an "ACK" and maybe return status (eg battery level and valve position).

    Z-Wave timer/roomstat?

    Is there a Z-Wave room stat that also contains 7 day timer logic? I must admit I cannot find any - only room stats that expect (I assume) to be controlled by a central programmer.

    I'd like...

    I'm wondering if ZWave might be worth a closer look - just come across it. Danfoss have the valves. There seem to be various room stats that may or may not work with the valves plus boiler interlocks.
