I have their Z-Wave based system. Not sure of the limits - I have 12 zones and 18 devices (and it shares airspace with another Z-Wave network).

The company is...

Hi,

I have a Fibaro Lite hub which is long in the tooth and not very programmable.
I also have: Fibaro Dimmer 2, Fibaro 2xswitch modules for lighting, TKB + Aeotech 13A plug switches, Aeotech Gen...

They are not exactly noisy - a small "whirr". Unless you are a very light sleeper, they would not wake most people.

I have a Fibaro HC-Lite, but the latest beta firmware is very unstable and they're not being very responsive to my requests to downgrade to an earlier known stable version.

I have a bunch of TKB...

Anyone tried one?

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.

I was looking for a few lights under Z Wave...

Thanks for going to the trouble to test that - pretty awesome.

I've ordered a starter system - 2 TRVs for the 2 bedrooms that will be zoned, the rest of the place will run with the current...

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...

Thanks Hot - that seems reassuring.

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.

One other question -

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

Am I right that if a user ups the temperature on the radiator valve with...

Hi Hot,

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

So the hub runs a local webserver? Or does the phone App scan the local network for a hub and use an API?

Whilst I...

I have a question for Hot which I don't think has been covered here:

What happens if Heat Genius go bust, bought out or for any reason their server disappears?

Is there a local web server on...

Thank you for that.

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).

As I understand it,...

Good questions to which I have answers :)

11-12 Stella-Zs

In most cases, one per room stat, in 2 cases, 2 StellaZs on a single room stat.

2 StellaZ's will be paired with a 2nd "boiler relay"...

Thanks - yeah - I did look at Heatmiser.

But I decided the wiring would be excessive and I'd need to drop wires to a thermal wax actuator at the radiator, or have a motorised zone valve in the...

Hi,

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.

Hi Fon,

No house stat - this is a new heating system (as in not yet installed) so I have the freedom to site equipment where I like :)

OK - so the biggest problem is remote control of the room...

Hi Fon,

In my case, the boiler relay is the critical element - FHT8W - that *must* operate.

There is no reason that has to be near the boiler - I am replacing all my wiring so I have enough...

Just before I get accused of wasting folks' time, I *just* came across this post:
...

** I have seen odd posts in other places that say having lots of FHT senders (room programmers) causes problems due to radio packet collisions.
This I understand - the protocol is simplex, retried 3...
