The dog is guilty.

We got a remote for my aging mother as she was not tech savvy

I was away from home and had a pet sitter there with my dog. While I was away I was receiving alerts on my smartphone from my HVAC unit. There were constant temperature fluctuations going on in my home that made no sense. I contacted the pet sitter to see if they were having problems with the HVAC system not working right. My pet sitter Linda told me that she was having to turn down the heating system all the time and had no idea why the temperature was randomly going up at all times of the day and night. I called my HVAC specialist to go check on my HVAC system, to make sure there was nothing major going wrong with it. Linda called me giggling hysterically. It seems that while the HVAC specialist was there the temperature on my smart thermostat changed drastically seemingly on its own. He went over all the wires and connections checking for a short in the wires from the thermostat and the HVAC system. He had Linda check the wifi connections to see if it had been hacked. Then in trotted Buster, my dog, with the remote control to the smart thermostat. We got a remote for my aging mother as she was not tech savvy. Buster had claimed our remote for the HVAC system as his new toy, incidentally changing the temperature randomly. Buster got his new toy taken away and the HVAC specialist had a story to chuckle about for a lifetime.
