Two days ago I installed two Blue switches in the same room. Both showed the green light, but I got this on my phone during the pairing process for one of them:
However, immediately after, both switches showed up in Z2M with LQI in the 60-80 range, and both showed online. I could control both, and they seemed to work fine, so I went on my way and forgot about the error message.
Twice now (in the last 48 hours), I’ve watched one of the two switches go “Offline,” even though it’s LQI has stayed in the ~60 range. When it first happened yesterday, I don’t recall doing anything, and it appeared back online about ~10 minutes later. Today, it happened again, but it’s been 20 minutes and it’s still showing offline.
Both are in the same room, and both have a similar view/distance to the closest router. Any thoughts?
