Hi everyone,
I’m using Panasonic P-FMM40 fan coils with the Wi-Fi Wall Module PCZ-EFB749. From what I understand, these Panasonic units are functionally equivalent to the Innova Filomuro with the INNOVA EFB749II controller. I’m currently looking for a way to integrate and control these fan coils through Home Assistant.
This integration just supports a local API and is for other Innova Devices: danielrivard/homeassistant-innova: Home Assistant Integration for Innova 2.0 Heat Pump and AirLeaf
Setup
- Fan coil: Panasonic P-FMM40 / Innova Filomuro
- Controller: Panasonic Aquarea Air Smart Wall-Mounted Control Wi-Fi (PCZ-EFB749) / INNOVA EFB749II
What I’ve tried
- Scanned the Wi-Fi module with nmap → no open local ports found
- Monitored network traffic and DNS logs
- Observed that all communication is cloud-based over HTTPS, with no apparent local API
Observed endpoints
The controller/app communicates only with:
- api.aquarea-home.solutiontech.tech
- core.grpc.panasonic.solutiontech.tech
- core.panasonic.solutiontech.tech
Mobile app
iOS app: Aquarea Home App - App Store
I also attempted to inspect the traffic using Proxyman, but the results were quite limited. I was only able to confirm the HTTPS/GRPC communication to the endpoints listed above, without gaining meaningful insight into the API structure.
Goal
My goal is to integrate this system into Home Assistant, ideally via a local API, or alternatively through reverse-engineering the cloud API if feasible.
If anyone has:
- Experience with these Panasonic / Innova Wi-Fi controllers
- Insights into the Solutiontech cloud API
- Knowledge of existing integrations or reverse-engineering efforts
…any help or pointers would be greatly appreciated.
Thanks in advance!
