Welcome to the ithowifi wiki!
To buy visit this page https://www.nrgwatch.nl/ (Dutch) or https://www.tindie.com (English).
This Wiki covers the installation and configuration of the add-on for both the CVE and non-CVE units, integration with home automation software and more.
The add-on covers various use-cases so consider these first before obtaining it.
If you have a supported unit and the right add-on, this allows you to control the Itho devices via the add-on webpage, HTTP API or MQTT.
Note: the add-on hardware and software is the result of reverse engineering and endless hours of testing and debugging. It is not endorsed or supported by Itho Daalderop.
The add-on hardware and installation steps differs per unit type.
-
Addon for CVE
This applies to the Itho Daalderop CVE-S and related units. -
Addon for non-CVE
This applies to DemandFlow, QualityFlow and HRU-350 and supported WTW units. -
Addon for WPU Heat Pump
This uses the non-CVE add-on but applies to Itho Daalderop WPU Heat Pump like 5G. This is today expiremental and is limited to reading status values only.
Once the CVE or non-CVE add-on is installed, automation is a logical next step. Use either the Web API or MQTT for the basics.
Guidance for modern home automation systems Home Assistant, Node-RED, HomeBridge and Domoticz is covered here
