HF garage door opener

I’ve seen several xAC garage door projects, but haven’t seen any high frequency versions yet so I thought I’d give it a go.

Ordered essentially the same module but in 13.56: https://a.aliexpress.com/_mO7BJLd

The PCB antenna WILL read an x series, but read range is basically 0” (0 mm for you tea drinkers). That wasn’t going to work once I sealed it inside a project box, so I turned to @Hamspiced for some repeaters (thanks btw Hammy…ordered Friday and they came in today. Awesome seller for anyone interested). In the right spot, with a thin plastic project box, I was able to get reliable scans.

Put the access module in a large box inside the garage, routed a bit of bell cable, and hooked up a 12v power adapter. Viola! Easy peasy. For those interested, this works great with my xSIID…no other implants tested yet. Although the read range is pretty good with standalone tags & cards now thanks to the repeater.
