Just support firmware tracking

I don't need all the features TeslaFi offers, but I would like to be able to contribute to the software update tracking. I wonder if it is worth having a "free" membership that provides very limited features but contributes to the useful data you are amassing on global deployments of the software.

Heck, personally I wouldn't even need any features. Just contributing the data would be a nice way for me to support what you are doing...
