Disconnecting Zigbee switches

I have tried a few aqara and some generic window / door switches and all my zigbee devices keep going inactive. I finally replaced my important switches with z-wave and so far they have been great. Anyone having issues with zigbee devices disconnecting. If I rediscover them by resetting them they come back but since I was using the one that failed last night to drain my aquarium to 10% and it took it to my safety limit of 60% because it disconnected, this is a huge problem. I need something I can count on. I always (maybe I shouldn't) do all the updates as they come out. So my hubitat is up to day. It's also a C-7. Any thoughts here?

By switches, do you mean contact sensors? Immediate thoughts would be a weak mesh. Do you have any non-battery devices?

I have two that plug into the wall, they havent been an issue. The one disconnecting all the time is less the 3 feet from the hubitat. No matter what brand I switch it out with, it fails. All Battery Zigbee loose connection after a few days and the only way to bring them back online is to re-discover them.

Yes, contact sensors.

What @FriedCheese2006 said:

@FriedCheese2006 is asking this because only line-powered zigbee devices function as repeaters for a zigbee mesh. A general rule of thumb is to have 1 repeater for every 4-6 battery-powered sensors.


Right, but proximity to the hub doesn't necessarily mean that it's connecting directly (although you would assume so). It could be attaching to a repeater instead and the problem lies there. Next step would be to use the new, nifty graph or even just the bare route table to answer that question.

To add to this, we know nothing about the nature of any potential repeaters and their capacity to repeat for the end-devices in question.
