Hi everyone,

 

I am doing some development work to add heartbeat support to Home Assistant when it talks to an ISY994.

 

I would really appreciate it if some people with Motion Sensors, Hidden Door Sensors, and Smoke Bridges could let me know what nodes appear in the ISY for these devices, and MOST IMPORTANTLY, what the subnode ID is for each of them. The subnode ID is the last number that appears for the device:

 

 

What I'm mainly wondering here is if the Heartbeat node is always subnode 4, AND if there are any other things that can end up occupying subnode 4.

 

I only have door sensors and leak sensors, and the behavior is consistent among them. I want to ensure these other devices will work with the code I am writing before I add them to Home Assistant.

 

Thanks!

My motion sensors are the original version (not current version).  Based upon my admin panel, they have only three nodes: motion, dusk/dawn, and battery.  None of the nodes show a number such as the one in your image.

Same here. None of my Open/Close sensors, leak sensors, hidden door sensors or (old) Motion sensors show the suffix you highlighted.

Motion sensors have no heartbeat and their battery low signal is very unreliable. It may trigger at weird times and your batteries will last for many months after or it probably will not trigger at all. I record all mine and keep a list. I have two of 11 units  owned that have sent low battery signals about two months ago and neither one has quit working yet.,

especially if the temps dip down and the ms is outside
