Homey is unstable

My homey’s totally unstable. Z-Wave, Fritz.box, Mi Flora, Presence,…almost every app.
Zwave plugs - manual switching does not work correct, lose Mi flora connection, lose homeyduino connection…ZigBee is okay :wink:
What can I do?
I use homey pro with latest software.

Try. A ptp (pull the plug) and wait 11.4 minutes before restarting. :pray:

…and why 11.4 minutes…is it a joke?
I am a new homey user…and also homee user…

Yup 11.4 minutes is a joke…on the forum just wait 10-15 min and put the plug back in and wait again 10 min so that homey can start up everything.
