It's nowadays so easy to create your own custom esp32 thing. I used to control a home battery installation. Used it on a old Landrover defender where we added a complete dash unit with digital gauges. Used it for controlling a Zigbee 12v switch to activate sprinklers in a garden. In combination with Claude one can create an entire setup in a couple days. Before I was sometimes spending a week on the lcd drivers alone.
