Getting a poweron detection into Domoticz

[philchillbill]

There's currently no link between Domoticz and the Honeywell Evohome Security (or Le Sucre) products but I'd love to have all my switch-timers only active when I'm away and the Security system is armed. I'm doing it manually now via telling Alexa that I'm going out but I'd like to have arming the system with an RFID tag do the trick directly. I've just ordered a Le Sucre smart plug SMPG-EU which uses the same RF protocol as Evohome Security and will switch power on or off depending on whether the alarm is armed or not.

Does anybody have any ideas for how Domoticz could detect that this physical socket is powered on or off? I could plug in some kind of transmitter that would send an RF event understood by Domoticz (e.g. I already have Z-Wave in use) but maybe somebody has a simpler suggestion?

EDIT: I did it in the end by plugging a Canary IP camera into that SMPG-EU and it (naturally) responds to pings when powered on but not when off. I have a script that pings it once a minute and from this I can determine whether the alarm is on or off.

I can not really follow your request. The Domoticz wiki indicates that Evohome is supported http://www.domoticz.com/wiki/Evohome
I don't have those products, but I hope that will give you a go.
P.s. I see a lot of topics on the forum as well.

Evohome HEATING control products are supported but not the Evohome SECURITY products (Alarm system). They use a different RF protocol and have no API.

After some google searches I expect this is a proprietary protocol made by themselves.
If you want to go all the way and start reverse engineer it... https://denglend.github.io/decode345/

Is there any webpage(interface) which can be accessed and read the data from or send commands to? I expect that would be easier.

Or buy z-wave devices instead...

Not a very helpful suggestion when my post made it clear I already have the Evohome Security devices, as does my signature. Also, the protocol is 868MHz so pointing to a 345MHz GitHub project is not that useful.
