That depends on what frequency your remote control uses. If your remote control is based on RF ranging from 300-868MHzthen Meross smart ceiling fan remote shall support it.
Yes. To control each fan independently, you'll need to add the remote with it's current settings. This will allow you to control the first fan. Then change the DIP switches in another remote to setup the second fan in the Meross app. You'll need to change the DIP switches in the receiver of the second fan to match the remote, so Meross can control it independent from the first fan.
