Appreciate all the work @joostlek put into bringing the SmartThings integration back to life. After deleting the integration back in January I figured I would give it another go. I have 11 Sensi thermostats connected using SmartThings. The problem I am a having since the update is random. disconnect of all the entities. I receive a 404 error in the HA mobile app on the dashboard page for the resource. If I go to integration and do a reload on the SmartThings integration the problem is immediately solved.

I am running HA on a Proxmox VM. I do a nightly backup which shuts down HA to perform the backup. The first time this happened I figured I was loosing connection due to a restart of HA. But that is not the case. This appears to happen randomly, not every day. Anyone have any ideas?

How do you mean 404? That sounds like something with your instance rather than the integration?

Do your Sensi thermostats show all available modes in Home Assistant? Only Heat, Cool, and Heat_Cool show up for me. SmartThings tells me it’s a Home Assistant problem. I can’t even turn the thermostat off.

No 404 errors for me though.

Yes. Using SmartThings I have the following modes. Heat/Cool, Heat, Cool and Off. Using Apple Homekit gives me the same modes but does not expose the fan modes or the humidity sensor.

The 404 error I see comes up on the bottom of by dashboard page containing a group of my climate cards. Al other cards containing all other entities function as normal. the only way to bring my climate entities back to life as I mentioned earlier is to go to Settings > Devices and Services > SmartThings > click the 3 dots and select reload. After reloading climate entities are again available.

Can you screenshot that

Has not happened the last view days. Next time it does I will screen shot it.
