Athom Apps keeps crashing Wi-Fi connection

I’ve got these Athom apps and Homey runs fine

  • Google Chromecast
  • HomeyScript (but do NOT start a script every sec, then it gets disabled)
  • Ikea Tradfri
  • KlikAanKlikUit (CoCo)
  • Spotify
  • tado v3
  • tado v1
  • Trust Smart Home

How do the memory graphs look, in Insights?
Do Fibaro, Hue and or HomeyScript use over 60 to 80MB’s sometimes?

How’s your wifi setup?
Some hints (not only for connecting a new Homey issues):
