I couldn't respond to this until now. I have had net metering 1.0 for 2 years (since January 2015) and I received the a letter that my plan is grandfathered in until January 2020. I also have net metering 2.0 in a different house and signed up for it in September 2017 and got a letter saying...

I think you can sign up for EV-TOU2 until December and it would give you peak from 12-6pm. You'd be grandfathered into that rate for 5 years.

My lease ended the first week of this month and I bought the car. I have 40K miles on it as well as the extended warranty. My lease was not an unlimited miles lease. My car has had its share of rather significant problems including 1. replacement of the traction battery at ~4K miles and 2. ECU...

Somebody has already done this adapter last year. Here's a link to the YouTube video. https://m.youtube.com/watch?v=V8EfD_kJdZU

I did have 3-4 EVs at one time for a short period including a 2011 LEAF, 2012 Volt, 2013 Rav4, and a 2015 Fiat 500e.

At my SDG&E true-up date, I paid $4.99. I lost $732 in credits that went unused even though I used 1,397 kWh more than I produced thanks to the beauty of TOU. This system supports a 4 bedroom house, a Rav4EV, Fiat 500e, and occasionally Volts. I also use OpenEVSEs that can be used to set...

Yay! I was hoping that this would come soon and that it's being done by my San Diego friend is a real treat! (Despite my preference for open source projects in the EV community). Developing a BMS as well as heating and cooling are musts that others who have added batteries to the Rav4 haven't...

Did I interpret the above statement right that those who paid $450 for a JuiceBox to get a rebate is now out $450?

I took the roadster out for the weekend - what a blast!

The Tesla UMC (and thus, JESLA) uses a 30A Potter & Brumfield DPST running at 40A. This may be why the electronics are not so robust. Here's a photo from Ingineer:

The problem is that your one appears to be a simple Voltmeter/Ammeter (similar to what TonyWilliams posted awhile back and which he intends to sell next year) whereas Jimbo's one is a multifunction power meter that incorporates more features including an energy usage meter in KWh.

The EchoHitches from Tork Lift Central are nice but even with $45 off, they are ~$200. For some cars, like the Volt or LEAF, these may be good options but for the Rav4, even with the discount, they are still $100 more expensive than competitors.

Dsinned, I can see how a causal observer may see similarities between JB and OpenEVSE. However, there are many more differences than similarities in the philosophy and thus product design & implementation. At its core, OpenEVSE came about from an enthusiast owner's (Chris) frustration with the...

Someone here asked me (jokingly I hope) if I could build one for them for Black Friday. I said no but Tony Williams' has a special on his Tesla UMC conversion with $100 off. It's not as versatile as this portable OpenEVSE but it is pretty slick.

I've been offline for a bit of time! I think you're spot on that understanding the CAN bus messages is key. In fact, the guys on the Orange County LEAF/EV club had been doing this including Garygid and others. I suspect that it's been slowed down a bit cos Gary got into Tesla decoding and...
