tomtom I haven't tried yet, but it is on my list... to rebuild the wallet from source on a RPI 4. Once you get that running you can start the daemon with ./sugarchaind and then you interact with it via ./sugarchain-cli You can get detailed help from each of the two exec files ./sugharchain-cli help (etc.) Hope that helps, post some updates here and I'll check in from time to time.
