Help with Garage door sensor

HI
Right now I can open-close my garage door with a 5V sonoff. I am looking for a sensor that will show if the door is open or close. My garage door is outside and sliding similar to this one

So I need to be waterproof and with batteries. I have a conbee2 and the wifi is available (not so strong signal though). I have tried an aqara door sensor which worked for a month but suddenly stopped working and it is somehow dead. (I can not even reset it). I don’t know what happend to be honest.

The 5V sonoff is located in my house and there is no easy way to have cables running in the garage (we share the same garage space with one more apartement.

Can you give me some ideas which sensor I should install please?

Grab any zigbee door/window sensor that reports open and closed and put it in a waterproof box. No need to waterproof the magnet bit.

Do you have any particular suggestions. Something that works?

No, I don’t use zigbee sensors. Someone else may have a specific suggestion.

I can recommend the Xiaomi Door/Window sensors, however I never tested them inside a waterproof box, but I see no issues with this.

I had this one, and although it was in a waterproof case (it was dry when I opened them) won’t work. I am looking for something else I guess because I don’t know what happend. I would appreciate if someone can suggest something that it is tested (for outdoor use) .
