Want to remote start a low cost generator via RF433Mhz using Raspberry PI???
For my off the grid cottage, I always wanted a low cost solution to charge my batteries remotely during the low sun season, specially when snow accumulates on the solar panels for a week or so, and accessibility is hard, so got a low cost, portable generator that works in cold season, with auto choke, on propane, with a remote fob. The idea was to copy the code from the FOB start and strop buttons and get a Raspberry PI to **automatically** remote start the generator when batteries are low, avoid me to drive to the cottage and manually do this. I did not want to spend $10K on a fancy generator and associated hardware and anxiety of theft risk. Now retired, I took the time to make this work. Made the code and documentation open source also :) Overall, it's less than $1000.
Code and documentation in the link below, and it work!!!
