C8-Pro; Platform version 2.4.3.176.
I recently started experiencing Zigbee network issues where my devices were sporadically reachable. I installed Dan Danache's awesome Zigbee Map tool to troubleshoot and validate things after testing the changes I made in my troubleshooting process. The tool shows that my LQI's are low and only hardwired Zigbee devices are making connections to the Hubitat directly. The issue with this is that my Hubitat used to make connections directly to some devices, and my 2 hardwired Zigbee devices were used to supplement other remote devices in other parts of the home. With that setup, I had full coverage of my home and a strong Zigbee network. Now, I only seem to be able to have devices connect to the hardwired Zigbee devices and none directly to the hub. This was not the case when I first installed the C8-Pro last year. I am starting to conclude that my ZigBee network is problematic in some way (perhaps the ZigBee Radio is weak now?). If anyone could help with this issue, that would be greatly appreciated. Here are the steps I have taken to troubleshoot so far.
- Scanned Wifi spectrum to see if there are any overlapping SSID's that could cause trouble for my Zigbee channel (Channel 16 with a 20 power setting). There were none, but I moved to Zigbee channel 25 with a power setting of 8 just to be safe. I also made sure my existing access points were using Wifi Channel 1 or 6. No improvement.
- I swapped antennas between the Zwave and Zigbee side. No improvement.
- I relocated the hub (and used another power adaptor) to another room out of my network closet and the hub connected to a Zigbee device in the same room, but nothing else. There was a Zigbee device one room over, but it did not connect.
- Deleted my 2 hardwired Zigbee devices and added them back in. No change.
- I also submitted a warranty request for the Hubitat team to look at my hub yesterday, but no response so far, so I thought I'd ask for help in this forum.
Thank you in advance for any help you can provide.
