Here's the procedure:
- You need V2 of the OVMS hardware. V1 is a whiteish plastic box with a built-in cable, V2 is a black metal box with a separate DB9 connected cable.
- You need the Tesla-specific firmware. The best place to get the latest version is: http://www.idleloop.com/tesla/ovms/. Note this site also has pictures of the boxes and instructions for upgrading the firmware.
- Once you have the box up and running in your car, and can communicate to it via SMS (Text message) and your smartphone (although smartphone isn't technically necessary), you can program Geo-fenced Homelink via ACC (Advanced Charge Control), which can only be done via SMS.
- If you only want the Geo-fenced Homelink feature, the following sequence will work:
Remember in the above examples we were using ACC slot #2, but you're probably going to use ACC slot #1. I used that to differentiate between ACC slots in OVMS versus HOMELINK slots in the car.
- Park the car near the garage or gate you want automatically opened.
- Send this text message (just what's inside the quotes) to the car: "ACC HERE"
- You should get a text message back from the car telling you what ACC slot you just created. I'm going to assume it's ACC slot #2 for example purposes, but you'll probably get back slot #1. At this point you can move the car if you want.
- Assuming you want the car's first slot for Homelink to be activated, send this text message to the car: "ACC PARAMS 2 HOMELINK 1"
- You should get a text message back from the car identifying the ACC slot and the parameters set. For instance: "ACC #2 39.123456 -125.98765 Disabled Homelink #1"
- Send this text message to the car: "ACC ENABLE 2"
- You should get a text message back: "ACC enabled"
- If you want to confirm everything send "ACC STAT" to the car
And you'll need to program HOMELINK in the car normally via the Roadster's VDS. You should be sure that works manually before trying OVMS's geo-fenced features.- Now drive away from your house - say a block or more, then come back home and viola! gate/garage will open!
finally got V2 of the box installed and going to play with this feature. Quick question. Is the ACC HERE command mark a particular location or distance? The reason I am asking is that I can approach my garage thru an alley from two directions. So if it's by distance I should be ok, but position, I would have to set ACC HERE for those two positions correct?
