Not sure where to start but I am working on a project that would allow integration the Gavita EL1 & EL2 Gen2 Master controllers with Home Assistant.
Typically these controllers are used to allow up to 40 lights per channel over a bus. The controller and bus is using a standard rj11 mod plug with 4 wires so I am assuming it’s a 232 or 485 bus.
The goal of the project is be able to get rid of the Gavita Master Controller and hopefully run some type of gpio or network/wifi to 485 bus converter over mqtt via Home Assistant.
Does anyone know of a starting point to find out exactly the bus type the Gavita master controller is using? maybe a 485 sniffer?
more info to come as try to flush this one out.
