Water Security remote 868Mhz Connect

Hello,
My apologies for being a newbie on Homey. I have an 868MHz remote that can close/open the main water pipe. I successfully managed to find an app that closes/opens my 433 Mhz blinds. I do not think the signal in the remote is very complicated. it is a switch with only two positions Open and Close. I have searched but not found a simple app on 868Mhz

Hello,

Homey doesn’t support 868MHz other than zwave
