Hi. Im trying to integrate my existing 433 mHz alarm system to HA.
What i want is to:
-Make HA sensors trigger the alarm system when armed
-Be able to arm/disarm alarm via HA
-Make the alarm system set specific scene/activate automation when triggered/armed.
However im really struggling on the first leg: making HA send commands to the alarm system.
My Sonoff RF is set up and works with HA via MQTT. (im able to see and read the device).
I have swiped a bunch of sites on the net, but still without breaktrough.
My config looks like this (three attempts on same issue)
Yes - I think it doesn’t matter - the Sonoff sends the data the same regardless of whether you specify in hex or decimal.
I don’t have an alarm as such, just a bunch of sensors and some HA automations that trigger the siren and send a SMS notification. The siren is configured as a switch:
When I was setting this up, I just used the command interface of the Sonoff bridge (running Tasmota) to test the commands. Saved a lot of mucking around editing YAML and restarting HA.
Im now able to read the codes from my alarm system panel.
However it seems like the panel only sends out the same payload when arming/disarming. Seems like its mostly to send a signal to the sirens to “beep” when activating/deactivating. -I would love to be able to read out the state-change. … but it seems like my Chuango S5 plus does not make me do that.
I still can not get the “send” command to work. -however i made a workaround, as i learned my Tasmota the required payloads, and can now use “cmnd/Sonoff_RF/rfkeyX” which works to me like this:
