Temperature Sensor Fluctuations in Living Room

Hey everyone, I’ve been experiencing some interesting behavior with my temperature sensors in the living room. I have three devices set up: two heating thermostats and one wall thermostat. I decided to create a graph showing the real-time temperatures from all three, and what I noticed was a bit concerning—there are significant fluctuations in the readings. Now, I understand that temperature can vary slightly, but these fluctuations seem a bit too dramatic to be normal.

To give some context, the current indoor temperature in my living room is already above the set target without any heating, which means the radiators remain off. Despite this, the sensors are showing these noticeable swings. I’m curious if anyone else has encountered similar issues or has insights into why this might be happening.

Could it be something related to the placement of the sensors? Maybe they’re picking up drafts or being affected by direct sunlight? Or perhaps there’s an issue with the sensors themselves? I’d love to hear from anyone who has dealt with this or has tips on how to stabilize the readings. Thanks in advance for your help!
