Hi, I got remote climate control working on my 2016 Nissan Leaf with OVMS v3. In the 2016 model year Nissan moved the TCU from the EV CAN bus to the Car CAN bus and they change the remote climate control messages slightly. The Leaf - OBDII cables that were sold with OVMS v2 were future proofed and when used with the OVMS v3 have the EV bus wired to m_can1 and the CAR bus to m_can2. Mark mentioned this a while back and I'm happy to confirm that it works. A "standard" OBDII cable only exposes the CAR bus. Sending the right message to the m_can2 bus with a Leaf cable starts up the climate control. I must thank Mitchell on My Nissan Leaf for providing the updated can frame, see http://www.mynissanleaf.com/viewtopic.php?t=24053#p496393 I haven't worked out how to turn remote climate control off and I haven't tested remote charge start yet. This certainty encourages me to look at the cellular situation -- we've got a bit of a heat wave going on in NZ at the moment. When I last tried the cellular data, it worked moderately well for a day or so and then stopped because it had used all of the free 1MB allocation for the month on the Hologram SIM. I see less than 1MB per month using the OVMS v2 on a local carrier. I haven't looked at whether the v3 data usage was caused by excessive communications with the server, Hologram counting data differently to what I'm used to, or the v3 code reconnecting to the cellular network often. Nearly at feature parity with v2!
