I'm looking to add steering wheel controls to my car. Ideally of course it would be ultra low power and it would only need to send a wireless signal when a button is pressed(short range).

the idea was to use a ESP32 with some form of wireless data sending method, a lipo battery, possibly even a small solar charger to extend the charge of the battery by hopefully a couple years if not "forever" and a accelerometer to wake up the ESP32 from deep sleep. Or is a ESP32 even the solution for my problem?

I've never done a project like this so any suggestions are welcome

Edit: I came across the Seeed Studio board using a nRF54L15 which is ultra low power and supports BLE which I think may be better suited for my application

Edit 2: Those were backordered so I'm developing my own board from the ground up

I've looked at a couple sites and they all give me the trulok / rubicon carrier bearings for the front D44 and I cannot find the non-trulok version

I left my vehicle off the battery for about a week. Once I tried starting it, it would absolutely not start. At first during cranking it would sound like it would get a ignition every couple revolutions, now it sounds like its just barely struggling to stay started.

My fuel trims are at -100 for some reason, the graph in the top right shows roughly -40,

its got fuel, air and spark. idk whats wrong with it
