Best keypad in a Zigbee/BT/Wifi HA system?

I’d like to use an outdoor keypad for things like an alarm system and/or garage door opener etc. If I google I seem to mostly find options that either seem specific to a brand (but maybe not … lack of info) or use some other radio frequencies, that require extra electronics etc to work with HA … I’d like the simple, but still good solution. Any ideas?

Hello voon,

I built something that doesn’t even need a pad specifically, can work with 5 actions done in the correct sequence. I use it with an RF433 remote from Sonoff, but it can be anything. Explained in the post…
