Beta Firmware Update

Hello, for using the HT in Home Assistent I have to install the beta Firmware.

How could I do that. In the App and WebIO there is no way to install the beta.

Thanks!

Okay thanks. I would try this.

But now there is another problem. I have done a Reset in the App, but now i could`nt find the AP to connect.

I push the button for 10 seconds so the led is flashing.
