When I ask the assistant to sync all devices (on my hubs, minis, phone or tablet), I get the response:
”Sure, syncing devices for 4 providers. 3 things aren't available. You might want to try setting them up again.”
This happens when asking using voice on Nest Minis or Nest Hubs, and also when asking the assistant app on my phone or tablet.
The 4 providers linked to Google Home are Philips Hue, Harmony, TP-Link Kasa and Nest (although Nest doesn’t explicitly show on the “works with Google” linked services list in the GH app).
Including “virtual devices” from Harmony remotes, my Google home app lists 31 devices, so it’s hard to identify what is the assistant struggling to sync, as the error message doesn’t specify which “3 things” are not available and all my devices seem to work.
If Hue is not available, the error message from the assistant is “syncing devices from Nest, Harmony and TP-Link Kasa, Hue is not a available”, and unlinking and relinking the Hue account resolves the issue.
This suggests that the issue may be Google Home struggling to sync with Nest devices (I have 3 devices added via the Nest app: a Nest Hello and 2 Nest Protects), but there is no clear way to unlink and relink the Nest service as it is not listed on the works with Google section of the app (it used to be), and all 3 devices seem to work.
Any ideas how to resolve this and how to identify which devices is the assistant talking about?
