Both my sensors show low heap memory comparing to othe sensors arouns. Haven’t found a solution here. Can anyone explain what is it about? Have a nice Easter guys!
If the sensors are working properly then it is likely nothing to worry about.
Is your sensor the same model, hardware, and software version as the others? The onboard memory size has changed over time. Older sensors have less memory and might have less free memory compared to later sensors.
Have you rebooted your sensors recently?
After looking at firmware versions on the map, it appears that sensors with the 7.03 firmware also have low heap memory. This is due to changes that were recently made with the BME680 and BME688. The VOC measurements should no longer get stuck at any value and the readings should correlate better with nearby sensors.
