Yes you can wire up to 4 opener buttons in parallel to the same opener.

EDIT: I know this because I figured it out while developing ratgdo.

The 882lmw wall mounted button requires 8.5mA of power. Other models will draw slightly more or less power.

It takes 50mA to pull the 12v line to ground (the buttons pull the line to ground to send the encrypted serial commands to the door opener).

50mA is the absolute maximum amount of power the 12v line can provide - however you need to leave some headroom.

So: 50mA - (4 * 8.5mA) = 16mA of headroom.
