Hello,
I'm wondering if there is a way to backup a shelly config on MQTT ?
My idea is to store the config in a dedicated MQTT topic. When config is changed on the device, it is saved in the related MQTT topic.
When shelly hard reset; it will try to reach MQTT, and restore settings from there.
For this; a static configuration containing "fallback" Wifi settings + the MQTT "backup" server should be stored on EEPROM (to survive reset); and I think the topic storing the "backup" config should contain the shelly device's MAC address to allow the device self-discovering its config and restoring it.
Is there something existing to achieve this currently ?
Thank you for your help
Best regards
