Power down and up again

Connect to tasmota device:

Wait some time until a “Need to login to Wifi” message appears, the login page is Tasmota. Or use 192.168.4.1 if the message does not appear.

Select your wifi, enter wifi password, save. D1 Mini will restart, tell you the new IP address and reloads after a few seconds. You should switch back to your standard wireless network, else this will fail. Now you are at the entry page and you can configure your device.

Enter MQTT data
