ich habe mir vor einer Woche einen Raspberrypi 4 zugelegt um das Haus mit Hilfe des iobroker zu "versmarten"
Das hat, auch dank Hilfe einiger Themen hier im Forum super geklappt!

Ich habe auch schon mit Iqontrol UI herumexperimentiert. Dort hat soweit alles geklappt.

Nun wollte ich mich in Material UI hineinarbeiten.
Allerdings funktioniert der editmodus nicht.
Es erscheint nur eine weiße Seite sobald ich auf den Stift zum editieren klicke.

Installiert habe ich den Adapter ganz normal über den iobroker (Adaptersuche)

Installcode:
Kommando-Ausführung: $ ./iobroker add material --host raspberrypi4-iobroker

$ ./iobroker add material  --host raspberrypi4-iobroker
NPM version: 6.13.4
npm install iobroker.material@0.12.1 --loglevel error --prefix "/opt/iobroker" (System call)
host.raspberrypi4-iobroker install adapter material

Ich hoffe ihr habt eine Idee an was es liegen könnte.
Vielen Dank schon einmal!

Adapter und Instanz habe ich schon mehrfach gelöscht und neu installiert.
Adapter IQontrol habe ich ausgeschalten (falls es einen Konflikt gibt)
Eine ältere Version des Adapters hat bei mir das selbe Problem.
UI im anderen Browser öffnen hilft auch nicht.

Design erstellt in Iqontrol UI welches ich auch im Material UI testen wollte.
