Just wanted to share a thing I built inspired by Ben Nelson's project DIY Home Automation Controller for Electric Car Charging - 300MPG.org.
I've been charging my TM3 LR RWD for 2 years on a 240v/20A circuit that I had before and was getting about 10-11MPH which was OK, but we just added a MY AWD and I needed to up the charging rate. I couldn't justify 1 wall charger not alone 2 and I've found my mobile charger to be more than adequate. I just needed a way for both cars to charge over night during the lowest rate available. I think Tesla's scheduled charging interface isn't very intuitive and lacks flexibility so I made my own dual charger smart switch with programmable times for each car and an over ride switch option with remote capability. Plus a voltage/usage reader that I can reset every month to see the total KWH I've used for charging the cars. Connected to an upgraded 50A with 6 gauge SOW rated wire and Nema 14-50, TM3 get's charged from 9pm to 2am and MY from 2:01am to 8am at 30-32MPH, it covers more than what we need for our daily driving
This was something I wanted and needed to do even if there is a software route available.
I know there may be some critical of my project, but that's fine, it works for me and that was the goal.
