Working but not easy to set up. Still not sure the modes are even set correctly. On line YouTube was better better for install instructions than company literature.
This came with a new home purchase, and it's been working fine. I've used a few Honeywell products in the past and had no issues. So many negative reviews because it depends on how it was installed and how familiar you are with smart devices I suppose. App also works fine for me and I used it with Google Home.
A little expensive for my liking but it is a really nice thermostat. I do like the fact I can set temperature for heating or cooling from remote areas (like my recliner) with my phone.
