My wall-mount garage door opener was pretty beat up when I moved in and has only gotten worse to the point the open/close button is cracked and is difficult to operate for my kids.
I would like to install a surface mount momentary switch for open/close functions as well as separate switch(es) for light control, and opener lockout (if it is necessary to have - otherwise omitted). How can I do this? I searched and haven't found details on how to do it yet, but suspect that it has to do with resistance value for each function. Would I just need to measure resistance changes as each switch is operated and put the corresponding value on the switch I want to replace?
I will run everything in conduit to the opener and safety sensors since I will be wiring the garage for new lighting and power circuits (separate conduit from low-voltage). I will also be installing a relay that will change state when the opener light circuit is turned on to power 1-2 shop lights instead of on-board lamps on the opener. The power for these will be fed from the sub panel with the lighting circuit on the opener causing the relay to open/close.
