Generally works with SMART MULTI S-series system (PUMY-HP outdoor + PEFY-P indoor), but...

I have a system that consists of two PUMY-HP48xx outdoor units connected via manifolds to 10 indoor units which are a mix of PEFY-P and PVFY-P ducted air handlers, and one PLFY-EP ceiling cassette. All units have a PAC-USWHS002-WF-2 interface.

The important parts -- temperature control and operating mode -- work fine!

Weird things:

• Every unit has a "dehumidifer" switch object. This doesn't seem to correspond to anything, nor can it be hidden.
• Every unit has a "fan" object (speed + oscillate) which does not seem to act on the units, nor necessarily correspond to the current state.

Let me know if there is data I can gather on this system that would be helpful for further development.

I deleted the devices and re-initialized as ductless_simple, and now this behaves as I'd expect. I can't adjust the fan speeds, but that seems to be behave unexpectedly anyway.

How did you delete and reinstall them in that way?
