I’ve got a new MCT-340 sensor that I’m trying to pair with ST. I no longer see it as an option in the new app, but did get it to pair using the old app. While it works fine in the old app, the new app says the device isn’t working and to try again. It didn’t appear as an option to use in the smartthings automations (in the new app). The API page also shows that everything is working fine.
I’ve removed the device to attempt re-pairing, and now I’m even having trouble with that. It’s not uncommon for me to not re-pair a device after deleting it from my system for some reason.
Update: I was able to pair using the new app, but the results are still the same (can’t open the device in the new app, but works great elsewhere).
