It is possible to connect an ESP module to this PWM input and control the Itho, but that requires technical knowledge, among other things. Out of a strong preference to have an integrated and as simple as possible solution available, this module was developed.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eWhat is included in the delivery?\u003c\/strong\u003e\u003cbr\u003eThe add-on is always fully assembled, loaded with the required firmware and tested. No special technical knowledge is needed to install the module. A simple flat-head screwdriver is sufficient.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRF module (CC1101):\u003c\/strong\u003e\u003cbr\u003eThe add-on comes with an RF module. This makes it possible to receive RF signals from the Itho devices (e.g. remotes). This way you can see, among other things, the status of the remote input on the add-on and in the home automation system, the measured values in the case of a CO2 and\/or humidity sensor, and the battery status if present.\u003cbr\u003e\u003cbr\u003eWith the RF module it is also possible to connect the remote controls directly to the add-on. This makes the status visible in your home automation system and allows you to set the speeds and timer settings for each button press. Control from the home automation system based on exact CO2 and humidity values also becomes possible this way.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eOption: Hum\/Temp Sensor for Itho CVEs\u003c\/strong\u003e\u003cbr\u003eNot needed for newer Itho models (cream white lid, CVE-S in the model name), these have a temperature and humidity sensor built in as standard. The add-on reads it out automatically.\u003cbr\u003eFor Itho models without a built-in temperature\/humidity sensor, retrofitting it with some tweaking is also possible.\u003cbr\u003eMore information about mounting this sensor can be found in the manual under the temperature\/humidity sensor chapter: \u003ca href=\"https:\/\/github.com\/arjenhiemstra\/ithowifi\/blob\/master\/handleiding.pdf\" rel=\"noopener\" target=\"_blank\"\u003eManual\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003eIf the temperature\/humidity sensor is ordered together with the CVE add-on, we make sure the required cable is included as well.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePlease note: Itho Optima Inside, built-in CO2 sensor together with the add-on:\u003c\/strong\u003e\u003cbr\u003eSome CVEs have a CO2 sensor built in (model CVE Optima \u003cstrong\u003eInside\u003c\/strong\u003e). The priority of the internal CO2 sensor is set by Itho and overrides some other inputs, which makes the control options slightly more limited than for models without a built-in CO2 sensor.\u003cbr\u003e\u003cbr\u003eMore information about the support and limitations together with this built-in CO2 sensor can be found via this link:\u003cbr\u003e\u003ca href=\"https:\/\/github.com\/arjenhiemstra\/ithowifi\/wiki\/CO2-sensors#itho-with-built-in-co2--sensor-cve-s-optima\" rel=\"noopener\" target=\"_blank\"\u003eItho CO2 sensors\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003eThis limitation does not apply to CVEs with an external (RFT-CO2) CO2 sensor (Optima instead of Optima inside).\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eModels confirmed to work:\u003c\/strong\u003e\n\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eCVE ECO 2 (this unit is also sold in Great Britain under the brand “Heatrae Sadia”) *\u003c\/li\u003e\n\u003cli\u003eCVE ECO RFT SE\/SP\u003c\/li\u003e\n\u003cli\u003eCVE-S eco ventilator RFT\u003c\/li\u003e\n\u003cli\u003eCVE-S ECO\u003c\/li\u003e\n\u003cli\u003eCVE-S PAK\u003c\/li\u003e\n\u003cli\u003eCVE-S CO2 (or OPTIMA inside) (the required extra-long headers are soldered free of charge, please mention this when ordering)\u003c\/li\u003e\n\u003cli\u003eHRU 150\u003c\/li\u003e\n\u003cli\u003eHRU 200 ECO (also sold as ‘Elektrodesign EHR 140 Akor BP’ and ‘Heatrae Sadia Advance Plus’)\u003c\/li\u003e\n\u003cli\u003eDuco 325\/425RF\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e* Please note, there are several CVE ECO 2 models in circulation.
