what are the dimensions of the sensors

Sensor Unit = W = 41mm D = 22mm H = 12mm Magnet Unit W = 25mm H = 10mm D = 10mm Hope this helps.

Does this device trigger Alexa routines?

So long as you have the gateway device, e.g. the E1, then yes. Otherwise it will be detected in Alexa but you cannot use it for anything.

do these things work with ZHA (in home assistant) or do i need zigbee2mqtt?

According to my Home Assistant friend the aqara devices work in Home assistant, but if you do use Home Assistant you can't use the Aqara App also. Only one or the other not both together. Hope this helps.
