Hi,

Has anybody some experience with the Heiman CO detector with Homey? I see that there is an Heiman app ([https://apps.athom.com/app/com.heiman](https://apps.athom.com/app/com.heiman)) so, I guess the device will work with Homey.

Which values gives the sensor? Does it return an actual co2 value (ppm)?

Thanks!

The app only reports the battery percentage and the co alarm not the actual sensor values. [HS1CA-Z device driver](https://github.com/slasktrat/com.heiman/blob/5d70b3be11961d8703a2f883d4b597b65fb7cb00/drivers/HS1CA-Z/device.js)

The device only reports the battery percentage and the co alarm not the actual sensor values.

It’s a device “limitation” and not something that is possible to add to the app.

Aha, thanks!  
Then I will look for an device which will return the actual values. Any ideas?

You could try NetAtmo, it is not cheap though. Or you could make your own with an esp8266/32 board and some relatively cheap sensors ([aliexpress](https://nl.aliexpress.com/wholesale?catId=0&SearchText=carbon+monoxide+sensor+arduino)).
