Following on from this morning's Meross Smart Garage opener post, here's another alternative at a fraction of the cost. I use one and it works great.
A couple of $ more than last time, price includes GST - which is added on at Payment stage. Compatible with a lot of garage door makes and models - basically if your model supports a wired button then there's a good chance it'll be compatible. There's instructions on how to check this on the webpage.
