Exporter does not report correct data

Problem

Exporter does not report correct data

Steps to reproduce

• Compile and install project
  • go get -v github.com/huhamhire/air-co2-exporter/...
  • cd [project_path]
  • go build
  • go install
  • sudo /home/[user]/go/bin/co2-exporter
• Curl fails to return valid metrics. See logs
• Note: node-co2-monitor test script does return the correct data

Logs

➜  ~ curl http://localhost:9110/metrics
# HELP air_co2 Relative Concentration of CO2 (CntR) in ppm.
# TYPE air_co2 gauge
air_co2{tag="default"} 0
# HELP air_temp Ambient Temperature (Tamb) in ℃.
# TYPE air_temp gauge
air_temp{tag="default"} 0

System

OS: Ubuntu 20.04
GO: go version go1.14.10 linux/amd64
CO2 Monitor: CO2Meter RAD-0301 Mini CO2 Monitor
Docker version 19.03.13, build 4484c46d9d

Note: I'm confident the CO2 monitor should be compatible, as I can run the test script based on node-co2-monitor project successfully.

It seems that new CO2Meter devices does not require data decryption any more. The node-co2-monitor just added this feature to support the TFA AirCO2ntrol Coach. I haven't got one of these devices to actually test with.

However, if you have tested with your device, I think it should be ported to this golang version exporter.
