Several days ago my new smart hub stopped reporting channels b and c. A channel still works. After following all troubleshooting "fixes" several times I still have problem. I bought 2 new sensors and still have problem. Great way to sell more temp sensors. Is there any way to tell whether I have been updated with your new firmware update. Is there any way to go back if I have? I have have had no problems like this in the years before I was forced to buy your new smart hub.
