Been using the same buttons as doorbells for a while. The biggest problem is folks don't look at it like a doorbell. We had to write "press me" on it for folks to use it unfortunately. The battery life has been great, they have withstood direct sun and indirect rain and snow. I also name each trigger ID after the door associated with the doorbell, so the message sent can send which door triggered it dynamically.
