So real long story short I migrated from a v2 hub to v3. Overall the process worked great and everything (knock on wood) has been stable. Except for two ZigBee leak sensors. Now the two that I’m having a issue with are in bad locations. One is at the drain under my furnace (big sheet metal return duct above it) and one is between my washer and dryer (between to big metal boxes). If I move them out of those spots and refresh they come back. So I did what I though was logical and started with adding a ZigBee outlet in the kitchen (first floor) about 8 feet from the laundry room and above the furnace (basement). I gave it a couple days but it didn’t help at all, both still unresponsive. So I then added another ZigBee outlet in the basement about 6 feet from the furnace and about 10 feet underneath the washer/dryer. This outlet literally has line of site (through a hallow wooden door) to the basement leak sensor and one standard construction (wood) floor between it and the laundry room. However after 3 days it seems they have not updated their routes.
Now there is a Ubiquiti AC-Pro access point in the basement near both these sensors but there is a third leak sensor just as close to the AP (and even further from the hub) that does work. I also changed the channel to be as far away from the ZigBee channel as I could. So I can’t blame that yet, especially since I have another AP on the second floor a few feet away from a leak sensor up there that’s fine. I went thought the SmartThings guide on wireless range and looking over everything the last thing to do was unplug the hub, wait 20 minutes, and plug it back in so these two leak sensors hopefully attach to the repeaters.
Did that, actually closer to 30 minutes since I forgot about it, waited 24 hours, everything back up except these two leak sensors. Physically move the leak sensors out from where they are and voila they talk.
Anything else I can do? I’m about to physically move the hub to a central location in the house, which is doable (have a outlet in the utility room, just have to run some Ethernet), but rather not if I’m missing something dumb. Also I have arrival sensors in both cars along with a multi purpose on the garage door that are all zigbee with no issues. I thought that when the hub was off the leak sensors would try to find a new connection, which would be the very close by outlets, but they didn’t seem to.
