What is it?

Open-source WiFi add-on to control itho central ventilation boxes

Control your* Itho Daalderop Eco Fan RFT with one simple add-on module
No hardware changes needed to the itho box, no warranty void
Control the speed setting of the fan from 0 - 254 through either a simple web-interface, MQTT or HTML API
Easily integrate this wifi controller in any home domotica system
Installation can be done in minutes
Detailed installation manual, download link provided with the order

Why did you make it?

Itho sells an add-on module that takes a PWM signal to regulate the speed of the box. It's possible to hookup an ESP module to this PWM input and control the box but I wanted an integrated solution which could be plugged directly to the itho main PCB without further hardware or changes to the box.

What makes it special?

One simple add-on module to make your home ventilation box from itho daalderop wifi enabled.

What do you get?

The add-on always fully assembled, loaded with the necessary firmware and tested.

Plug it into the itho, configure wifi/mqtt and you are ready to go.

This second revision adds the possibility to solder a CC1101 RF module on the back side to be able to receive itho remote RF signals. This way you can see the status of RF remote input on the add-on and in your domotica system. The add-on can be ordered without or with CC1101 RF module. If you order it as a kit you have to solder the CC1101 module yourself. There is also and option with the CC1101 module soldered on and fully tested. Please choose when you order.

Use case for the CC1101 RF module

Itho designed their fans to give preference to RF remotes and build in RV sensors. This means you can use the original remote but this input will not be represented in your domotica system. With the CC1101 module it is possible to connect the remotes directly to the add-on. This will make remote input visible in your domotica system and enables you to control the speeds and timer settings for each button press.

Use case for the Hum/Temp Sensor

The latest (those with the light grey lid) models of itho units have a built-in humidity sensor. This built-in sensor controls the itho unit and has priority over the add-on and can't be readout reliably. This replacement sensor measures humidity and temperature and reports this to your domotica system. You can then decide for yourself how the itho unit should react to those values.

Models confirmed to work:

CVE ECO 2 (this unit is also sold by the brand 'Heatrae Sadia' in the uk) *
CVE ECO RFT SE/SP
CVE-S eco fan RFT
CVE-S PAK
CVE-S ECO (CO2 and/or OPTIMA) (If you have a model with built-in CO2 / OPTIMA sensor, please contact me for the possibilities)
HRU 200 ECO (also sold as 'Elektrodesign EHR 140 Akor BP' and 'Heatrae Sadia Advance Plus')
Duco 325/425RF
Please note that there are different CVE ECO 2 models in circulation. The most important is the 2×4 pin interface that must be present on the itho main PCB (encircled in red on the fifth image). Only if this interface is present the add-on will work.

Maurice | Feb. 10, 2021

Works as advertised - would recommend

Bought it along with the Wifi board. plugged it in, followed the instructions and it was up and running. Am using it to control the ITHO fan with my home automation (Homey). No issues so far.

Reinout | Feb. 9, 2021

Amazing👏

Great project, works very well. With the provided instructions the setup was quick and easy. In combination with Homey it took no time at all to setup a smart ventilation schedule

Gerwert | Jan. 22, 2021

Works perfectly

Fast shipping, easy to install and works as advertised.
Innovative product, hopefully creator has time to keep developing this and similar products.

Vikaash | Jan. 8, 2021

Works like a charm!

This product is very, very, VERY good. It installs like a breeze, the manual is short and clear. The creator made an excellent API for HTTP as well as MQTT. I am not an IT guy, but I was able to install it and link it to my hub (hubitat) throuh the http api.
I hope in the future someone can write some drivers for popular hubs like home assistant, smartthings and hubitat.

Easy to install on the ventilator .
The ventilator is also to use as normal.

Eymert | Dec. 16, 2020

Great for easily making your Itho CVE box HA-controllable

Board designed by a fellow 'Tweaker'. Really innovative product, that plugs directly in the Itho CVE "central ventilation" box's mainboard and makes it's RPM speed controllable in an almost 'stepless' way.

P | Dec. 3, 2020

great product

Works as described.
Just plug-in and it workst out of the box with a nice webinterface were you can configure youre HomeApplication.

Remko | Nov. 22, 2020

works great

I needed something to control my ITHO box, I saw.
This solution was just what I needed.
Now I can control my box via mqtt and Domoticz.

Wim | Nov. 17, 2020

Awesome addition to my Itho CVE RFT box.

High quality item.
Plug 'n Play
Ultra fast shipping.

Got this device working in minutes.

This is way better than fiddling with 868Mhz transceivers.

Wouter | Nov. 10, 2020

Works like a charm

Plain and simple, just as it's supposed to! Installation was a breeze with the clear instructions, got my Itho added to my home automation system in less than five minutes. Thanks for this great add-on!

Remko | Nov. 10, 2020

Flawless!

So I ordered three modules (v1.3) and it works flawlessly. It is amazing, finally a 'connected' mechanical ventilation unit.

Please note: as of now this device do compete with the Optima variants of the Itho Daalderop CVE-S. The Optima variants have an additional module for the CO2 (carbon dioxide) and relative humidity sensor similar to the add-on module.
