Kasa app works fine but Google Home and Google Assistant cannot reach any Kasa smart plugs
I have 10 smart plugs: HS105 and HS110. I can reliably turn them off and on using the Kasa app and using Alexa devices. But for some reason Google Home / Google Assistant stopped working after months of reliable service. I have checked the router and assigned static IP addresses to all Kasa plugs. Rebooted the router.
Note that in the Kasa app if I turn off wifi on my phone and only use LTE, all smart plugs can be remotely powered off and on. (I realize that Google Assistant depends on remote access.)
I have tried linking and unlinking the TP-Link Kasa account multiple times. The Home app consistently lists all plugs in the correct home and room for each. Is there anything I can do to further troubleshoot the problem?
