I've recently upgraded to the latest hub and I seem to be having a couple of issues with the rules.
A couple of my blinds don't always work - they are quite far from the hub, but I thought most zigbee devices were supposed to act as repeaters, so I'm not sure why these aren't doing it correctly. Is there a repeater I can get if not? The house is full of mains-powered zigbee devices - smart switches and that kind of thing...
To piggyback off of what @dstutz asked, how are they supposed to be working?
Do you have automations configured that automatically adjust the blinds? Do you manually control the blinds from a Hubitat dashboard? Alexa, Siri or another voice assistant?
In general this is true, so you probably don’t have a lack of repeaters as the underlying cause of the issue you’re experiencing. But what devices are they?
I think you should get them responding to commands from the hub reliably before worrying about automations. The latter will probably start working OK once communications are reliable. I'm not a master zigbee mesh network guy....but the above seems to make sense.
