Itho Daalderop is a Dutch maker of ventilation systems, heat pumps and hot water boilers for homes. Newer products are set up with the Itho Daalderop Service-app by installers or, for the Smart-upp and Green Energy boilers, controlled with the Climate Connect app. Smart home links for ventilation units mostly come from community projects and third-party Wi-Fi modules.
Itho's own connected products use a Wi-Fi link set up through the Service-app or, for boilers, through Bluetooth pairing in Climate Connect. We found no official Itho page for Alexa, Google Home, Apple Home or Matter. Smart home control of ventilation units usually goes through a third-party Wi-Fi add-on module that speaks MQTT or a web API.
That suits tinkerers who run Home Assistant, Homey, Domoticz or Node-RED and are happy to fit an unofficial add-on to an existing unit. It is weaker for people who want a vendor-supported voice assistant setup, because the add-on project itself says it is not endorsed or supported by Itho Daalderop.

An installer app, tagged as a service app for installers. It offers setup wizards for products such as the WPU 6G, MZR and HRU 325/375, manual control and settings screens, QR-code connection to a gateway, Wi-Fi module registration and backup or restore. The App Store page links to Climate Connect for energy consumption. Reviews on the page report connection errors. We could not verify a Google Play link.
The owner app for Smart-upp and Green Energy Smartboiler units. It switches between Smart control, clock program, continuous and standby modes, shows boiler energy level and savings, offers a hot water boost to 85 degrees C, and supports PV self-consumption with a P1 module. It pairs by Bluetooth first and then takes Wi-Fi details. We could not verify store links, so the manual is linked instead.

Climate Connect boilers join the home Wi-Fi after a Bluetooth pairing, and the Service-app registers Wi-Fi modules on units. Third-party add-on modules for ventilation units also connect over Wi-Fi and are covered under open platforms. We found no Wi-Fi band specification.
Itho's brochure says ground-source heat pumps come standard with an IoT chip, with a monitoring subscription under 35 euros a year, and that CO2 sensors and DuoZone sensors talk wirelessly to the units without naming the technology. A boiler RF Repeater accessory also exists.
Not offered by Itho. The community homebridge-itho-daalderop plugin exposes ventilation units and a CO2, humidity and temperature sensor to HomeKit, and only works through the Itho WiFi add-on module.
No built-in integration for Itho ventilation or heat pumps found, and the vendor does not maintain any. A custom integration installable through HACS reads the add-on's MQTT data for WPU, HRU, CVE and Autotemp units, and needs Home Assistant's MQTT integration. It states it is not affiliated with Itho. A Home Assistant page titled Itho Daalderop Spider returned a removed-integration notice when opened.
A third-party Homey app by MonkeySoft supports NRG.Watch Wi-Fi modules for Itho CVE, WPU and WTW units over the local network, and the store page says Homey Bridge is required. The store lists Homey Cloud and Homey Pro, but a forum thread covers Homey Pro only, so we could not resolve which applies. A separate community app, Itho Daalderop Amber, controls the Amber heat pump over LAN, also needs Homey Bridge and a separate control module.
An open-source ESP32 add-on, built by reverse engineering, that bridges Itho's I2C protocol to Wi-Fi. Per its wiki it covers CVE ECO and CVE-S boxes, HRU 200 to 350, DemandFlow, QualityFlow, WPU 5G and AutoTemp, some read-only. Control is by MQTT or web API, and the wiki says it is not endorsed or supported by Itho Daalderop.
