Philip, I need to correct you on some of your comments I'm afraid.



Not correct. There are three mood settings which are stored on each dimmer. The app on your phone, or a paired physical...

You may be someone who likes apple kit, you may not but FWIW, I have an Apple Timecapsule (an Airport Extreme would also work) and an Airport Express. The Airport express 'extends' the Wi-Fi network...

The original LightwaveRF Forum hosted by JSJS Designs at lightwaverfforum.net has been closed and all posts and traffic redirected to the new unofficial LightwaveRF Community at...

It seems that the Germans have put much more R&D into heating control and us brits are more than happy with our dated central thermostat and TRV set up. There seems to be two ways to go with this....

Mine's fine too.

There are many many systems out there which offer iphone control. Smart phone control is going to be a requirement for any system hoping to be viable in the market for any length of time. The...

While not directly related to 'home automation', I wonder if any of the heating engineers on this forum might be able to help.

I refurbished my bedroom last year and this included replacement of...

Thanks for your reply. This is indeed interesting and although I have to admit that most of it goes over my head, it does make me wonder how poor my installation must be.

The background...

John, I've just replied to your comment on my blog. Thanks for leaving it. Re-reading your original post reminded me that you have a system boiler. The FHT8W only has one relay so can only be used...

I have installed a number of these: FHT80BTF from Conrad-UK.

While they do shut down all the radiators, control of the boiler is achieved through something called an FHT8W boiler interlock. I have...

I started small by installing a kit similar to one of these: FHT80BTF, it is th same as the Househeat system (only much cheaper) and I think is manufactured by ELV.

It is aimed at full zone...

I've had the conrad system installed for a couple of years. I am very happy with it and coming from what I had (a 25 year old boiler with a timer attached), my system is now infinately better.

My...

Hmm, yes, definitely looks like a bug in the FHEM PGM2 code.

Personally I don't use the web interfaces at all. I have a native app on my iPhone and for my graphs, query FHEM's XML interface. ...

Sorry yes, report1 and report2 not reset!

I also have a "define wakeFHT at *00:40:00 set TYPE=FHT time"

In terms of FHEM config, all I have that is relevant is:

define FHZ FHZ /dev/fhz1300pc...

Sorry, no experience with using the CUL - I have an FHZ1300PC.

Are you getting anything from the FHT's ? For what its worth, I do find a regular 'reset' of the devices helps by sending the "set...

Vettal, its a real shame you are experiencing the problems you are. I am up to four dimmers, three appliance modules and the WiFi link and had no problems with any of it.

I even have timers...

Maybe we should ask the mods to create a dedicated LightwaveRF Forum here on AutomatedHome?

That way we can openly discuss the system and protocols with little interference from JSJS designs. ...

If anyone is interested, I have some graphs up on my blog which show stats from my FHEM installation.

Heating in the bedrooms is a bit erratic at the moment due to a faulty TRV - I have to use the...

I am no sparky so take proper advice before installing one of these, but for what it is worth, it is just a relay. You need a 240v supply to power it, but beyond that, I think it just switches what...

Not sure about the CUL devices as I don't have one but as for your other comments, yes, this seems about right. The devices only transmit periodically. The reason for this is twofold, firstly it...

The FHT 8 is one way only - it will report its status, but is not capable of being controlled.

The FHT 80 on the other hand allows two way communication hence it being a little more expensive and...

My belief is that they are pretty intelligent devices and think about how much they need to open (or close) in order to obtain the temperature you desire. The thing with radiators is that they...

I think the FHT80b only sends actual temperature readings when they change so if your temperature is relatively constant, you may not see anything reported.

With mine, I try not to get too hung up...

Could it be how hard it has to work to drive the TRV valve? Could replacing these with new ones quieten it down a bit?

One thought, how early are you switching to comfort temperature? If too...

Back when HouseTech were selling both online, they explicitly stated that they were not compatible even though they look similar. I suspect it is down to the protocol used over the air. That said,...
