Feature Request: Meter Pro (CO2 Monitor)

[ozTahu]

Problem

Any chance of adding support for the Switchbot Meter Pro(CO2 Monitor)??

https://www.switch-bot.com/products/switchbot-meter-pro-co2-monitor

The plug picks up the temperature and humidity just fine but the tile for CO2 has "Not detected"

Solution

Add support for CO2 reading

Can you try the latest beta?

[ozTahu]

Hi there, I have installed the beta version, the tile reads "Not Detected" and I received the following error message. Hope that helps. Thanks for your time and effort. ``` homebridge | [1/13/2025, 4:17:53 PM] [SwitchBot] WARNING: The accessory 'Meter Pro (CO2 Monitor) DA' has an invalid 'deviceName' characteristic ('Meter Pro (CO2 Monitor) DA').

that's because of the name that you are giving it. you can override that error in the config by going to advance settings and checking the allow invalid characters but this could potentially cause issues in the Home App.

Awesome, thank you for looking into it. I have changed the name in the switchbot app to just "CO2 Monitor" but now I get the following message. Also, the temp and humidity are not reporting the correct values either and seems to be stuck at 30 and 50%. Thanks again for your work. ``` [1/23/2025, 11:00:46 AM] [SwitchBot] Restarting Process...

Can you post logs of the device receiving data from the API?

[ozTahu]

No sure where I get the logs from device receiving data from the API?

This is the debug logs I'm getting at the moment from the plugin.
