I'm aware that lots of updates to C8 following the teething problems with zwave and Zigbee reliability. There have not been any updates for a while, and whilst mine is better, I still only get about 90% reliability on Zigbee and zwave devices.
Can you please advise where we are with this? Is it as good as it's going to get or is it still being investigated?
Can you please send me a private message along with your hub details so we can take a look at your engineering log to see what may cause the lower than expected reliability rate?
