### What issue do you have? Please be as thorough and explicit as possible.

H5101 was able to get all stats automatically at first, but now only seems to ever update battery percentage. So it does see the device on Bluetooth and updates, but not temp and humidity data. I was actually amazed to see it work out of the box, but then appears that it won't update just those parameters, but does see the devices, as it updates battery. It does show that the devices are offline in the settings, but the log shows battery updates. As I look through though, they don't change much. The log just notes device being reported offline.
