Sensors all "unknown"

[Qhilm]

I have an airgradient Open Air, I added it to ESPHome plugin, installed air-gradient-open-air.yaml on it, and it appears online in the ESPHome plugin, and I can ping its IP. So far so good.

The problem is, all sensors appear as "unknown", so I must have missed something obvious.

I am thankful for any pointers.

I forgot to mention, I did check the logs, and it seems the airgradient is not working properly, but I have no idea why. I keeps sending "nan" values:

[18:04:33][D][sensor:094]: 'AirGradient Open Air Relative Humidity': Sending state nan % with 1 decimals of accuracy
[18:04:36][D][sensor:094]: 'AirGradient Open Air Temperature': Sending state nan °C with 1 decimals of accuracy

If I open the ESPhome web page, it seems many sensors are duplicated, maybe HA is getting readings from the duplicates which are in stated "NA":

Reading the yaml, it appears my issue is, no data is read from uart_pm2 somehow. Still at a loss as to why that is.

man, I didn't see it, but I have an O-1PST model, that's why...
