"User input malformed" when re-configuring an integration.
Brand new install of HA OS. Brand new HACS.
When using programmable thermostat I can set up the integration but I can't re-configure it thereafter. Seems there is a bug somewhere, and the latest 2011.11+ version highlights it.
"User input malformed" and I can't save changes.
Example:

A few other integrations are having the same issues I see: adaptive lighting for instance.
I'm having this issue as well. According to https://github.com/home-assistant/frontend/issues/10608 it sounds like the problem is with the integration, not HACS or HA.
So there was an update just the other day that included the fix for the front end. That fixed it for adaptive lighting, although I had to remove and readd the integration. Tried that with programmable thermostat but it still has problems. I think it's related to how you choose entities etc and if it's as a dictionary or array of somewhere?
I installed this fresh on OS Version: Home Assistant OS 6.6 Home Assistant Core: 2021.11.3
and I also had the issue, so I went for manual configuration. As we need to enter the full entity paths, I find that easier.

Maybe something has changed in HA and I didn't noticed it. In this moment I'm pretty busy for some presonal topic. I'll try to fix this at next run when I'll set up my new home. If you have idea of how to solve it feel free to PR your changes.

I had the problem and succeeded to sole it by using cut/paste for the same field
