Will spanking my Zigbee sensors work?

I'd also recommend a channel change. If you do decide to go that direction it can take a while (thinking overnight) for everything to catch up. You also have two devices on the neighbors list with pretty low link quality. Not sure if it matters or not but it does pop out. One is the master bathroom diffuser, which to me indicates (shocking) a signal strength issue in the master bathroom. Not news but at least it confirms.
