Is the CA10P control panel sufficient for home light and alarm automation?

well, that's exactly what I need

On the website they have a tab: "Contract manufacturing".
And I guess it's not a problem to pack the PBM-05 electronics into a can housing...?!
Especially since the subject is brought up here because there might be a "market niche" (switchable element for the can, controlled by low voltage ....po twisted pair).
"Sell" them the idea...hihi...for the small dozen pieces you need

Gentlemen I found something like this:
http://www.tme.eu/pl/details/rmb841-2z-12vdc/...omagn-miniaturowe/relpol/rmb841-2022-35-1012/

It will probably fit what ?

For this you need a base - so it will be big anyway (most often the base is a TS35 rail component). The second problem is switching control: you need to feed the correct polarity for 'on' and the opposite for 'off'.

but why do I need a can holder? I only need to bring the connectors out to the PCB and it will fit somehow.
worse, the integra has no possibility to change polarity...

Therefore, it is better to look for two-coil bistable relays, e.g.http://www.piekarz.pl/pl/?item=45074
Two signals from the Integra: "on" - "off" to two coils.

i don't know why, but I was convinced that every additional pulse on the coil turns the relay on/off.

A two-coil is also a bit of a bummer because it takes up the outputs, and I still have to count the input from the switch so I can manually turn on the light too o_0
