There is also some form of integration directly to the smart meter and/or E.ON databases using a code on the smart display provided by E.ON. USwitch, a UK company that provides comparison data for a number of areas, including energy contracts, uses this to access a customer’s historical energy data
**Are you willing to loan or donate to a developer?**
Happy to beta test and provide access to smart display code if this is the chosen development approach.
What is/are the device(s)/service for type:
EV charging station. Specifically the Ratio chargers managed through the official Ratio app (including the Ratio Solar). The app would show charging status and power, and allow starting/stopping a charge.
What kind of category/signal(s) would the app use:
Via the cloud API behind the official Ratio app (AWS Cognito authentication + REST). Optionally also Bluetooth (BLE) for local control without the cloud (the charger uses the Inspiro IPC protocol over BLE).
Is there an (public) API / documentation / manual(s) or known (other) implementations (like Blogs/Github etc)?
Yes. There is an open-source, reverse-engineered Python client and a working Home Assistant integration:
aioratio (async Python client for the Ratio cloud API, including optional BLE): Github
Home Assistant integration by the same author: Github
The API is not officially documented by Ratio itself; the projects above document the endpoints, the Cognito authentication flow and the data models quite thoroughly in their READMEs.
Are you willing to loan or donate to a developer?
Yes, donate money
Extra information:
There is no Ratio app in the Homey App Store yet. A working prototype build by myself (with Claude and no programming knowledge) already exists, built with the Python Apps SDK + the aioratio library: pairing with a Ratio account, plus capabilities for power, charging state, car connected, charging blocked, grid-operator power reduction (DSO), error/fault alarm, firmware-update available, and (approximated) kWh.
Please follow the template in the first post. Also, I can’t find any mobile app for these cameras. Can you share the PlayStore/App Store link for the app?
REIRI is a Daikin control system that can manage air conditioning, heat pumps, ventilation and other connected devices. A Homey app could display and control REIRI management points, including:
On/off
Current and target temperatures
Heating, cooling, fan and automatic modes
Fan speed
Ventilation mode and status
Equipment status and faults
Indoor-air-quality measurements, where available
These capabilities could then be used in Homey Flows and Advanced Flows.
What kind of category/signal(s) would the app use:
IP (Local/Cloud/WiFi);
Other: REIRI communicates with Daikin equipment and can also integrate selected Modbus and Z-Wave devices.
A local IP integration would be preferred. REIRI controllers connect to the local network, and Daikin’s technical FAQ identifies network ports 80, 52000, 52001, 52010 and 123. The exact local protocol does not appear to be publicly documented.
Is there an (public) API / documentation / manual(s) or known (other) implementations (like Blogs/Github etc)?
There does not appear to be a publicly documented third-party API. However, the following official information and applications may help:
Daikin New Zealand – REIRI for Home:
Daikin Australia – System Controllers:
Daikin REIRI product information:
Official REIRI technical FAQ, including network, Modbus, Z-Wave and Google Home information:
REIRI Setup Tool for Android:
REIRI Setup Tool for iOS:
A separate REIRI user application is available for controlling the system.
REIRI already has a Google Home integration. Daikin states that air-conditioning and Z-Wave management points can be transferred to Google Home. Available air-conditioning controls include on/off, target temperature, operating mode and fan speed. This indicates that an existing interface for accessing REIRI management points may be available, although it is not publicly documented.
Are you willing to loan or donate to a developer?
The controller forms part of a permanently installed system, so it cannot readily be removed. However, I would be willing to assist a developer remotely with testing, diagnostics and non-sensitive technical information from an operational REIRI system.
Extra information:
There is currently no known Homey app supporting Daikin REIRI.
An initial read-only app would still be useful if full control cannot be implemented immediately. Ideally, a completed integration would provide Homey capabilities and Flow cards for:
Reading current temperatures
Reading and changing temperature setpoints
Turning equipment on and off
Reading and changing operating modes
Reading and changing fan speed
Monitoring ventilation operation
Monitoring equipment availability and fault status
Triggering Flows when temperatures, modes or operating states change
Local communication would be strongly preferred for faster responses, operation without an internet connection and avoiding reliance on a cloud service.
