I use a Simulated Alexa Switch to start and stop activities on my Amazon Echos.
I set up an Automation in the ST App to turn off the switch after 2 hours.
It has worked fine for a long time but now the switch doesn’t turn off.
I also have one that turns off after one hour and it works.
If I shorten the time from 2 hours to 1 minute it works…
Not sure why this started recently…
