Problems with Home since iOS 16

I’ve been having issues with Home since iOS 16. Specifically

• automations that turn off a wireless outlet in the evening are not working. In the morning our 3 lights are still on. I have Wemo and Meross outlets.
• when we ask Siri to turn on a light, there is a pause and we get a message about the light “is taking a while to respond”. Most times it eventually comes on. But it takes much longer: 15-20 seconds rather than 2 seconds to come on when it does come on at all.

I’ve rebooted all my devices (phone, apple TV, wireless outlets) and restarted my router. Nothing fixes it.

Im ok with the delays. I’m not ok with the lights on all night. Any suggestions? Is there a log of when Home tries to turn things off and on?

I’ve googled “is taking a while to respond” and don’t find anything related to the latest iOS, but that is when the problems started.
