HA Ducted Air Con System?

Hi all, I was seeking any recommendations for Ducted Reverse-cycle AC system, with 4x Zones.

I would like to retrofit my existing Actron AC ducted system with a replacement AC unit. Current system has 4x simple 240vAC Zone dampers which energise to open and spring closed.

I would like to keep some classic wall controls (for guests etc), but add support for control through HA/Smart Home.

Current smart home is about 40 devices, mostly Tuya-based or Sonoff lights and switches, and I have a Zzh! stick (CC2652R) for Zigbee. Native HA or HACS addons are working well with all devices.

Desirable features:

AC control: on/off, modes (heat,cool,fan,auto), temperature (+/- °C), fan speed (L,M,H), timer.

Zone control: 240vAC 4x on/off

So far I see Polyaire Airtouch range, but I'm concerned that the tablet controller and software (Android-derivative) is proprietary, unconvinced they will maintain it sufficiently to be exposed to internet, and their controller and motors are 24v so would need complete ducting replacement (adds a good $3k to the cost).

Daikin Airbase can add a Wifi control to a classic wall controller which is more what I'm after. But their newer wall controls don't integrate zone control. So I could perhaps complement this by putting the zone controls on a separate 4x Gang Wall Switch (wifi or zigbee).

Any suggestions from our HA/Smart Home enthusiasts?
