Hey everyone! I wanted to share my experience with grouping temperature sensors in my garage. It’s been a fun project, and I hope others might find it useful or even get inspired to try something similar.
I have a 3-bay garage, and while my thermostat is in Bay 1, the heater is in Bay 3. This setup means that the temperature can vary quite a bit across the space. Initially, I only had one sensor at the thermostat, but I noticed that the temperature near the heater was significantly higher. This discrepancy made it challenging to maintain a consistent temperature throughout the garage, especially during the colder months.
To address this, I decided to add another temperature sensor on the opposite side of the garage. My goal was to aggregate the readings from both sensors to get an average temperature. This way, I could ensure that the entire space stays at a consistent 52 degrees without overcompensating in one area.
I set up a rule in my smart home system that triggers a notification if the average temperature drops below 45 degrees. This has been incredibly helpful for catching issues early, like open doors or low propane levels. However, I did run into a bit of a challenge with data aggregation. The system I initially used only considered the furthest sensor, which skewed the readings. After some research and tweaking, I found a way to average the two sensor readings, which has made a world of difference.
If anyone else is looking to optimize their garage heating or improve temperature consistency in a large space, I highly recommend experimenting with multiple sensors and data aggregation. It’s a simple tweak that can make a big impact!
Happy tinkering, and feel free to share your own experiences or tips below!
