Currently, I have a push button (SW) controlling a device (DEV1). What I would like is to another device with the same push button (SW). I measured the voltage on DEV1's and DEV2's push button inputs, and I got 5v and 2.45v respectively.
Is it possible to have a single push button controlling both devices? What should I do with respect to the difference of voltage between DEV1 and DEV2?
The devices are two swing gate motorizations. They both have push button input in the form of 2 screw connectors as shown below. Both devices are looking for dry contact.
Furthermore, my ultimate setup will be replacing the single button with an output signal from Meross RSG100 WiFi garage opener kit as follows:

Depends on the devices but if they can tolerate a minor voltage change, you might try something like this. Components selection may need to change based on your specific equipment. I just put the volt meters in to illustrate the voltage on the load is somewhat lower than without the diodes. I don't recommend this method... But in a pinch...
