Too many TSTATs ...

Folks. I've got a 6 zone hydronic heating system and 3 zone ducted heat pump system (primarily for AC) all with independent TSTATs. Any ideas re: how I can consolidate to less than 9 TSTATs? Thank you

Do the heating zones & cooling zones overlap more-or-less 1:1? You'll likely run into problems if the zones don't, although averaging sensors may alleviate that.
Also, what kind of existing controls do you have?

Hey Ratio. The zones essentially overlap. The heat pumps are Mitsubishi, the hydronic controls are TBD.0

The Mitsubishi PAC-US444CN is an adapter to allow a standard thermostat to control your mini splits, see http://mylinkdrive.com/USA/Controls/InputOutput_Modules/Thermostat_Interface_for_Module/PAC_US444CN_1?product. It will operate them in heating and cooling mode, but NOT with a standard heat pump stat, it does not use an O or B changeover signal. This will make auto-changeover from heat pump heat to hydronic heat difficult.
You may want to look in to Kumo Cloud (https://www.mitsubishicomfort.com/kumocloud), Mitsubishi's automation framework. I have no experience with this, but IIRC others here do.
