Indeed, what @JB2K wrote.
And meanwhile you can use another usb supply of at least 2A. Less won’t work.
Perhaps you have a ipad charger you can use. Any reliable charger of at least 2A will do.
I have recently had a problem with Netgear MESH that was enabling access control and, for reasons still not understood, adding devices to the blocked list
From what I"ve experienced, when an app keeps using more and more memory, and it goes past 70 to 80MB’s, I can’t connect to Homey for a while.
The wifi part of Homey seems to ‘choke’.
I created flows wich restarts the ‘suspect’ apps when they reach that limit.
The app you installed today is most probably one of them. Which app was it?
To find out which apps:
Via my.homey.app Insights you can view historical system load and memory use of Homey and apps.
Enter ‘system’ in the search field for Homey
And enter ‘app’ for an app listing.
