I recently installed 3 CT101 Thermostats (multi-zoned system). I had no c-wire easily available, so am going just battery operated for now.
I am using the stock handler for the CT100, which is giving me humidity and battery reporting (in addition to temperature, setpoints, etc).
My question is that the battery reporting keeps fluctuating. For instance, last night my downstairs one said it was at 95%, but this morning it reports 100%. Just wondering if anybody else is having this “issue”. Obviously I’d love it if the 100% is correct, but I care more about a correct reading.
