Error in Prometheus Exporter docker "Undefined array key "rco2"" #36

Closed LimesKey closed 1 year ago

LimesKey commented 1 year ago

My CO2 Sensor isn't working right now due to this issue. I am using the Prometheus Node Exporter in the docker hub, then when I pass the data to Prometheus I get the error message strconv.ParseFloat: parsing "<br": invalid syntax.

I get this because the air-gradient-Prometheus exporter is sending an error message which includes HTML tags that Prometheus doesn't like. The data it sends to Promethus is below, and it doesn't like the HTML <br> tag.

I tested this with my working board that has CO2 readings correctly, and I still get this error so it cannot be caused by that. This must be some issue with inside the docker file or using the default AirGradient-supplied Arduino INO File. They are probably not compatible. I cannot use Jeff Gerling's INO file since I have the AirGradient Pro with the SGP30 (TVOC) sensor.

I have no idea how or what, but I was just fiddling around with it more and it got fixed.

I set my string API root to, String APIROOT = "http://192.168.1.100:9982/"; Then I set my Prometheus Exporter docker to use port 9982 and I set the network to Bridge.
