Thank you that seemingly worked (Display is on and it shows AP) I try to update the firmware now.
Edit: yes that worked for me. I was able to update the firmware and can control the device again.
Ich habe ein ähnliches Problem, wobei bei mir auch der Motor die ganze Zeit weiter dreht. (The TRV engine does not stop) ggf. hängt es auch nicht zusammen, aber zumindest bist du mit dem Problem erstmal nicht alleine. Eine Lösung gibt es noch nicht.
Have you tried holding the start button next to the USB port for long time? 10-30 sec?
Yes. it is not responding to it. Buzzing continues and Display shows nothing. AP is also not on
I have the same Problem. It also doesn't show any UI and does not react to any Button press. It just continues Buzzing.
I really hope it is not destryoing itself through it.
I let the battery run empty in the hope, that it hard resets itself. I'm not sure if there is an easy way to open the case and reset it without voiding the varranty?
(having no mechanical hard turn off button is kinda a design flaw imo)
