I don't know of anything here, but there's a discussion on the HA forum about it that might give you some ideas if you haven't seen it.
If it's just one remote, you could always just hack the remote. Close three different relays to close contacts on the three buttons. I did this for an iSmart Alarm once. No integration outside of a very slow IFTTT service, so I just used a Xiaomi dual relay connected to two mains voltage relays to give me two, no voltage dry contacts. Soldered those dry contacts to the button pads on the remote and added a 5v to 3.3v buck converter so the remote didn't need a battery.
Worked brilliantly to give me instant, local arm and disarm of iSmart Alarm via HE (although iSmart Alarm has now been replaced with a Ring Alarm). I do similar for my Aqara hub. It's has a (not very loud) siren feature, but it can only be triggered by a Xiaomi sensor. So I use that same aforementioned method with the relays dry contact soldered to the reed switch of a Xiaomi Mijia contact sensor. That then triggers the Aqara siren anytime the RIng Alarm is triggered.
