This device comes preflashed with Tasmota, but will still require a little configuration. You will need to:
- Run “Backlog Weblog 3; so65 1; Module 75” in the Tasmota console
- Upload the EmberZNet firmware using the “Firmware Upgrade” feature
These steps can be taken using the device’s web interface, and do NOT require wires/soldering/disassembly.
Digiblur’s Configuration Guide lays out these steps in detail and also walks through adding the device to Home Assistant.
