No, as far as I know you’re not the only one with this problem. That’s why I suspect it’s a bug. My recommendation is to switch back to the HP19 and wait to hear what Athom support has to report. Before you switch back to HP19 please read this [post](https://community.homey.app/t/howto-homey-pro-early-2023-migrating-from-homey-pro-early-2016-2019-with-early-access/77516) **first**!
