Interesting, I might check that out, although at $50 its a bit steep. I'm pretty sure the CoopBoss is the only Zigbee device I have, all the switches & other stuff is Zwave. My SmartThings is in the same spot it's always been on the top shelf on my desk with a direct line of sight though the window 40-50' or so to the coop.No errors under the Recently tab for the CoopBoss, just a handful of status & voltage stuff that shows up for a couple minutes, then nothing until I reboot the CoopBoss again, then a few more messages, then nothing.
As it's just the remote control part having issues & the button works fine, it definitely seems like it could be the Zigbee module or something with the connection. How much is just that module & where did you source it?
