- Prerequisites. Must have Zumungo Relay firmware running on ESP8266 or ESP32 connected to MQTT. For example MQTT topic is Home/Zumungo/MultiRelay/Input
- Take a note of the local IP address of the board. For example 192.168.1.161
- Issue this command over MQTT to the above topic OTA?Name=Screen, URL=www.zumungo.com/wp-content/uploads/firmware/ElegantOTA.bin, pp=test1 pls. Note that www is NOT preceded by http://replace the name of the board and password with real ones, otherwise copy the command exactly as shown
- Allow 1-2 minutes for ElegantOTA to install.
- Go to 192.168.1.161/update (for the example above, real IP address will vary) and confirm that you see the ElegantOTA interface.
- Download the latest Zumungo .bin file that you want to install from locations as specified here
- Rename the file to end with .bin Example: downloaded file: ProjectR.bin-esp8266 change it to ProjectR.bin
- Go back to the ElegantOTA web interface at 192.168.1.161/update (for the example, your IP will be different) and select the bin file that you just renamed.
- This works for Relay firmware (ProjectR and ProjectR1) for ESP8266 and ESP32
