Ugh, I was working on a DIY smart lock. "I'll use Matter!" I naively thought.

Ok you need a border router for Thread support. No problem, I'll buy one. Should be cheap right since an ESP32 can handle it. Nope! You pretty much can't buy a standalone border router. All the articles are "don't worry, you might have one already if you have a Nest Hub or a Home Hub or...". Well I don't have one.

Pretty lame. I guarantee if they make a vendor neutral border router dongle you can just plug into your router's ethernet port and sell it at cost price (like £5) they'll see triple the uptake.
