I bought one of these to use Homelink on an existing opener: HomeLink Receiver – 2 Channel – Tessories The unit works and the transmitter that came with it works well with plenty of range. But Homelink only works sometimes (maybe 50%) and only from very short range (a couple metres). Homelink activates properly both auto and manual but the door doesn't open. Anyone else have any success with this or recommend some other receiver?
I know a few people on the Facebook group have it set up. However, the main Model 3 pages on these forums are probably a good place to ask
I bought that receiver and modified it by adding an antenna (5/8 wip) and mounting it on top of the garage. That increased the range from a few meters to about 60m. The Model 3 transmitter is behind the front bumper, so the signal is still poor when driving away from the garage. Now works reliably when set to 12m. I can send photos if you are interested. (On holiday at present).
Thanks and good to hear it's possible. I've got a 1/2 wavelength wire as an antenna on it now and only need it to open when the car is pointed at it as it closes on a timer. When you get back, if you can post a photo that would be appreciated. Enjoy the rest of your holiday (we're away too)
