I want to enable an automation (or something else if that works better) that if 1 smoke alarm triggers that my other smoke alarm also triggers.
I have 2 Heiman smoke detectors (SmokeSensor-EM by HEIMAN) and after a bit of reading it should be possible I think.
But the question is how?
Do I need to issue: zha.issue_zigbee_cluster_command or zha.warning_device_warn? Or is this completely the wrong approach?
Can someone help me on my way?
