With the help of Turbo Techie Systems, a custom wiring harness was made to connect the existing RV control board to an ESP32 relay board. This allows for each component on my RV control board (water pump, water heaters, generator and slide functions) to be controlled through WiFi and Home Assistant. You can see the impressive work in the images below. What you can not see in the picture is that Turbo Techie made this very easy for me to install. He color coded each wire on the new relay board to match the existing RV wire colors. Additionally he labeled each wire grouping as well as the connecting ports for the power. Red to red, yellow to yellow, colors to colors and the install was complete. Before I knew it I was saying "Luna, turn on my gas water heater." Yeah, that was nice to do from bed when I woke up. After a day or two I took things even further. Now I have my first automation set up to Turn On my Gas Water Heater at 0700. When this automation activates, I have it set to trigger my LED Strips to turn Red to remind me it is on. At 0730 the second automation kicks in, telling the Gas Water Heater to Turn Off, and my lights to resume their previous setting.
