I too have a Vera Plus and the firmware used is OpenWRT. That is the base linux that the Vera controllers are built on. I don't know if theUI for the Vera Edge is the same as the Plus, but on mine if you go to Settings > Firmware in the left menu, it should check if there are any firmware updates available. It's always best to run the latest firmware available.

Automatic node ID's are now also supported! There is a step-by-step install guide here: https://github.com/tsathishkumar/MySController-rs/issues/30 You can easily run this alongside Domoticz. Burn an image for the Mozilla Gateway onto an SD card. Follow the guide above to install MySController-rs. Install Domoticz at port 8081 and 444 (instead of 8080 and 443, as the Mozilla Gateway is already at those ports).

@Redferne Thanks. I'll check it out.
