An outline on interfacing Hometronic to Comfort.  More to follow......

Comfort can control Hometronic Lifestyles via a Hometronic HX10.

This gives 5 Lifestyles (via '5 sensors' on the Hometronic Menu).

This can be an X10 (A1 - A5) Mode (not tried) or 5 O/C Outputs (not tried) or Relays Mode (tried)

I think there can be up to 3 x HX10 i.e. 15 Lifestyles.

From Dean at Sensible Heat:

For the purposes of simplicity and explanation we'll assume the normal (non-active) state of the input[s] is open circuit, active is when contact closes.
 
All inputs 1-5 transmit status to the Manager unit upon change of state.
 
At the Manager, Lifestyles can be invoked at either or both the 'up' edge of a contact closure (open to closed) or 'down' edge of a contact closure (closed to open).
 
The Lifestyles take place temporarily, in such a way that rooms set to fixed temperatures during activation of a Lifestyle stay at that setting until their Time/Temperature Schedule (used for normal operation) goes through a scheduled switching point, even if the input which brought about the Lifestyle is still active.
 
Once all rooms have been through a switching point the Lifestyle is cleared, hence generally Lifestyles only last up to 24 hours or so.
 


Only Input 1 differs...
Input 1 (if DIP1 set) will retransmit every 2 mins after contact close as long as the contact remains closed.

 
Hence to gain permanent activation of a Lifestyle using HX10 inputs without being cleared by Time Schedules, either use input 1 with the relevant DIP setting, or program Comfort to re-activate the input (whichever) periodically every hour or half-hour say.
 
Lifestyles are mutually exclusive, only the last called is active and supersedes other previously activated Lifestyles. They can also be called or scheduled through the Manager Unit.
 
-----
 
So if Relay on Comfort Output 8 is linked to HX10 Input 1
 
Response: Hometronic_1
 
Output Output08 On
Output Output07 Off
Output Output06 Off
Output Output05 Off
Output Output04 Off
 
 
 
Then use the Hourly Misc Event to repeat and override Time Schedules.
 
-----
 
Note also that there is probably a fair bit of duplication / overlap of functionality / modules  between Hometronic and Comfort e.g. dial-in.
 
I will try and get a link to the HX10 manual.

Also belive that there is a comms port to Hometronic. However this is a bit of a closed shop requiring someone like Cytech to buy the rights to develop integration via this. Think Crestron and AMX have done this already.

I think is called locking you in and minimising competition?

Hi Just joined this forum today so here goes first post

I work for Sensible Heat I would be happy to work with Cytech to develop a driver, its not a closed shop we are trying to avoid supporting individuals developing drivers, just to avoid having to support them. I have fitted several comfort systems for family and have integrated my system just lowering all the room setpoints when were away

If anyone wants any further information drop me a line

Hio Jason, Is there any documentation on the Hometronic protocol?
The new Universal UCM see http://www.comfortforums.com/forum94/2126.html has been designed to communicate with any 3rd party device on Rs232 or Ethernet with a wide range of baud rates etc

The radio protocol is not published but I can supply you with the our gateway protocol so you can trigger lifestyles, display room temperatures and adjust setpoints etc.

Communication is all done over IP

We supply two types of gateway a web interface for 3rd party integration and a web manager for full control via Internet browser.

If you drop me an email I will send over the protocol to you.

Regards

Jason
