Horrendous Functionality & Zero Customer Support

Good luck if you make the mistake of purchasing a product from this garbage company. When things stop working, you’re on your own. I’m currently locked out of my own home system and haven’t gotten a response from customer service in 5 days. I’m throwing my device in the trash.

An app that doesn’t work

It is absolutely a useless app. It never worked and it apparently won’t

Long suffering customers of this hideous app

I despise trying to make this investment live up to minimal expectations. For those on old oil boiler systems there aren’t many options.

Worst app ever

Never seen an app that just doesn’t work.

Junk

Poor functionality. And similar to reviews below, the app no longer works correctly to reprogram a thermostat. So it’s stuck in manual mode.
