Thanks for the testing!
I can imagine that the status of the KAKU devices is not shown correctly. After all it is one way traffic! My problem is, that the status of the devices (KAKU or Z-wave) shows correctly in Homey, but not in Google Home. So it somehow doesn’t sync properly.
I also checked the group associations, but they are all correct. So that doesn’t seem to be the problem. And as I mentioned, the status of the devices shows correctly in Homey.
The Google Home/assistant reports back (in most cases) that Homey is unreachable or offline. When I use speech to switch a light it even says: 'Light switched on/off" followed directly by: “Can’t reach Homey”. The light did actually switched on/off, so that one works, but the feedback from Google Home/Assistant is ‘strange’.
So I decided to (again) reconnect Homey to Google Home. After removing my Homey-account the devices in Home weren’t removed. This was because my partner also had her Homey-account linked to Google Home. Next step was also to remove her account. Then all devices were removed.
After reconnecting my account, the Google Home-Homey connection finally came to live and I can control all devices! I also reconnected the Homey-account of my partner to ‘her Google Home/Assistant’, and it still works.
So 1 Homey is now linked with 2 accounts to 1 Google Home and ‘2 Google Assistants’. I don’t really know the advantage of the 2 accounts yet. Anybody found out yet?
She can’t sync the devices to Google Home (that’s only for the account that added Homey, so that’s me). And it also doesn’t seem to be in personal favorite flows or something like that.
On second tought: last step I wanted to see what happened if I would disconnect the Homey-account of my partner, but her Google Home app doesn’t show Homey as a connected service. So maybe her account isn’t connected in the first place, because that Homey was already connected to Google Home? Anyone has experience with this?
But I can control my lights and flows again (with my voice) via Google Home, so that seems to be worked out (for now). Thanks for all the help!
