Integration with PebbleAir controllers

Hello

I did a quick search for this type of controller and it seems that the only type of integration is with a Harmony hub, which I’m not too thrilled about since I’ve had a spotty history with the harmony remotes.

Basically, PebbleAir has nothing to do with the smartwatch, it is a thermostat/remote for a new series of mini split heat pumps I’m having installed right now. These will be hardwired into the home and will communicate with the heatpumps to control the temperature and get data from the unit. Here is the website for the manufacturer: http://pebbleair.com/

I’m guessing that they would need to make their API public before any integrations could take place. Is that the case? Has anyone integrated these devices with their SmartThings hub?

Thank you!
