Hello
I have 3 outdoor Air Gradient kits - 1 Model O-1PST and 2 Model O-1PPP. These units all use the PMS5003T sensor for temperature monitoring.
It was pretty cold where I am last night - getting down to nearly -10°C. Looking at the history of all the units they started to mis-report temperatures. Here’s a snippet of the logs of one of the 1PP units that has 2 PMS5003T units in:
[07:38:45][D][sensor:094]: ‘Temperature (1)’: Sending state 6552.89990 °C with 1 decimals of accuracy
[07:39:28][D][sensor:094]: ‘Temperature (2)’: Sending state 6553.20020 °C with 1 decimals of accuracy
Here’s one of the other 1PPP units reporting:
[08:17:36][D][sensor:094]: ‘Temperature (2)’: Sending state 0.00000 °C with 1 decimals of accuracy
[08:18:07][D][sensor:094]: ‘Temperature (1)’: Sending state 6553.39990 °C with 1 decimals of accuracy
and the PST unit:
[08:19:31][D][sensor:094]: ‘Temperature’: Sending state 6552.50000 °C with 1 decimals of accuracy
My tempest weather station (different hardware) is currently reporting the temperature as -8.2 °C at the time the logs above were taken. I’m assuming it Is too cold for the Air Gradient units to report temperature? What’s the expected lowest temperature they can record? I’m running the units via ESPHome so I could potentially put some lambda logic to report the lowest possible temperature, instead of 6500°C!
