Statische IP-Adresse vergeben
If you are familiar with ESPHome, you can pull the yaml for the devices into ESPHome and uncomment the static IP lines and add your information there.:
tube_gateways/models/current/tubeszb-zw-kit/tubeszb-zw.yaml at main · tube0013/tube_gateways · GitHub and compile new fw with the static IP.
If not familiar I’m happy to do it for you if you provide the IP address, Gateway and Subnet you want to use, I can then send binaries which you flash over USB using the microUSB port on the Olimex ESP32-PoE boards and eb.esphome.io
