You’re definitely right. Padlocks are a option for many types of gate latches. Somehow, I managed to confuse myself and thought you were referring to the latch itself for some reason lol.
But Looking at this for a Wyze perspective, they’d probably want to go for a full latch retrofit for gates.
This doesn’t mean that they should disgard the idea of a BLE lock however, a quick Amazon search shows a few Bluetooth and fingerprint locks for around $40
Hoping this discussion can bring up interesting ideas for Wyze.
