This product has been discontinued in June 2023. You can get the new model with Ethernet here.


The Gateway E32 (Ethernet + WiFi edition) is the current Gateway model that is everything you need to add your EMS devices to your home automation system.
In features it’s almost identical to the Gateway S32 but it comes with an additional RJ45 Ethernet port.
This Gateway has a wired AND wireless network connection, so you can choose which one suits your situation best.

Just plug the device into the service jack on the boiler with the optional EMS service cable and stick it to the side of the boiler / heat pump.
If your system does not have a service jack, you can also use the EMS/thermostat wires in parallel to the thermostat or another EMS module.
No additional cables are needed and everything is powered from the jack itself or from an external 12V power adapter.
Its all neatly packed in a nice and small enclosure (90x50x24mm) that fits into your hand.

The Gateway connects via Ethernet and/or WiFi to your home network.


  • Plug-and-play connection to the EMS bus with one cable
  • Connects to the EMS bus via the service jack or the EMS/thermostat wires
  • Based on the ESP32 with 4MB flash
  • 2.4GHz WiFi connectivity
  • RJ45 Ethernet for wired networking
  • EMS-ESP firmware V3.5
  • Responsive webinterface
  • New: English, German, Swedish and Dutch language selection (more to come)
  • Configured for Home Assistant
  • Supports the Home Assistant MQTT Discovery protocol
  • MQTT Discovery now also works with Domoticz and OpenHAB
  • MQTT and Restful API for other interfaces like NodeRED and Loxone
  • Telnet console
  • Optional DS18B20 temperature sensors
  • Supports all EMS heating circuits
  • Support for EMS, EMS+, Heatronic 3 etc.

Supported EMS device types (See the full list here):

  • Boilers
  • Heat pumps
  • Thermostats
  • Solar modules
  • Mixer modules

Power options:

  • Service jack (with the optionally supplied EMS service cable)
  • 7-12V DC (with the optionally supplied power adapter)

If your boiler or heat pump has a service jack you do not need the DC power supply, only the jack cable.
If your system does not have a service jack, or it does but you want to mount the Gateway elsewhere you need the DC power supply.
You can add your own 12V DC power supply later on but I only support the power supplies that can be ordered with the product.
UK buyers: the optional power supply has a 2 pin Euro plug!
Do not use cheap audio cables for the service jack as these have very thin wires inside. Only use the optional EMS service cable below. 

On first boot the Gateway will create an access point on which you can login with a browser and make the appropriate settings for your own network. So for this kit you don’t need any soldering or real programming skills. You do however need to properly configure your home automation system. For Home Assistant, Domoticz and OpenHAB the MQTT discovery is available.

It has an additional connector for directly connecting Dallas 1-wire DS18B20 sensors. You can connect multiple sensors in parallel.

The Gateway can be plugged into the service jack of the boiler, or you can connect it to the EMS bus via the thermostat wires instead. In the latter case you need to use the 12V adapter.
Because the Gateway is an ‘always on’ device it contains high quality components like Panasonic, Samsung and Murata components for maximum longevity of the device.

Included in the kit:

  • Fully assembled and tested Gateway E32 (Ethernet edition)
  • Self adhesive strip
  • JST ZH cable for connecting external DS18B20 sensors (sensors not included).
  • optional: high quality EMS service cable for the service jack
  • Optional: 2-pole Euro plug power supply with 12VDC output and 5.5mm DC barrel jack connector (center pin positive).
  • Optional: 3D printed wall bracket (Its this one)

For all details about this product look at the extensive EMS Bus Gateway product Wiki.
Please consult the information pages before purchase.

The Gateway comes fully assembled, tested on an actual EMS boiler and loaded with the EMS-ESP firmware.

You can download the manual here.

The current firmware of the Gateway already supports the long list of these EMS devices.
If your device is not listed, it might very well be fully or partially compatible. In case you are missing parameters, you can always open an issue on the firmware repository to get support.
If you have an old Nefit Ecomline, Buderus GB112 boiler or the control panel on your boiler looks like one of THESE, then your boiler is not EMS based but iRT. The Gateway will not work on iRT boilers nor is there any support in the firmware.

    Work flawlessly with a Junker Cerapur ZSB 28-3 (and a Junkers FR100 thermostat) via parallel connection on the EMS bus. Datas sended to a MQTT broker. Web interface available and easy to use as the firmware update. A nice have compared to the price and usability of the official Bosch-Junkers MB LAN2 gateway.

    Nefit Topline Compact HRC25, Moduline 300 ( is nu EasyComfort CT200 ) Mosquitto & Domoticz(een stable en Beta) op Raspberry Pi. Tot voor kort alleen met ESP8266/DS18B20 allerlei temperaturen gemeten.
    Met de BBQkees/Gateway, en ook met “P1” data (eigen ESP32) van de slimme energie meter, nu perfect een goed inzicht in gebruik en instellingen. En het allerbelangrijkste de foutieve instelling van de CV radiatoren kunnen vaststellen. Plus de Moduline bleek verre van lineair met de kamer temperatuur. Vervangen door de CT200 die het prima doet.
    Het is jammer dat de CT200 gegevens (nog?) niet uitgelezen wordt.

    It was installed in 10 minutes and since then, it’s working like a charm. I’m impressed!

    Auf Grund eines Tips unseres Heizungsinstallateurs habe ich mir das Gateway E32 bestellt. Was soll ich sagen? Es hat sofort hervorragend funktioniert. Ich betreibe es an meiner Buderus WLW196i Wärmepumpe und habe das Gateway über die Anschlussklemmen mit dem EMS-Bus der Heizung verbunden. Die Einrichtung des Gateways war selbsterklärend, das Handbuch ist aber auch vorbildlich und ermöglicht es auch Laien, die Installation selbst durchzuführen. Sämtliche Daten der Wärmepumpe erschienen sofort im Webinterface des Gateways. Ich verwende das Gateway, um die Daten in meinen ioBroker zu holen, was ab Tag 1 unkompliziert und zuverlässig funktioniert.
    Mit einem kleinen PoE/DC-Konverter betreibe ich das Gateway an einem PoE-Switch ohne zusätzliches Netzteil – sehr praktisch.
    Ich würde das Gateway sofort wieder kaufen, ein hervorragendes Produkt.

    Had a bit of trouble with the EMS Tx-connectivity, but after updating the firmware to from 3.4.0 to 3.4.2 it now works basically flawlessly with a Buderus GB172 Boiler and RC310 Thermostat. It’s nice to monitor all the parameters and set heating water flow temperatures in Home Assistant in accordance to my radiator thermostats, so there is no gas wasted heating water that is not actually needed to heat the house. Thank you for the great product!

    Uitstekend hulpmiddel om inzicht te krijgen in het gedrag van de CV ketel (Nefit). Aangezien we een ander huis hebben gekocht is de stook historie voor ons een onbekende factor. Door deze gateway kwam ik er al snel achter dat de warmwater voorziening (ingebouwde boiler) continu op temperatuur werd gehouden. De ketel op eco stand gezet en nu doet hij dat nog maar af en toe. Dat spaart een hoop gas. Middels deze gateway wil ik de “eerste winter” monitoren om een beter gefundeerde keuze te maken m.b.t. overgang naar een WP systeem.

    Cool device – even with very good knowledge base.

    Used to control a Buderus Boiler and Thermostat (GB192i, RC310, RC100). Because the useage of the building is very irregular I read out the Google event calendar and have on a RPi (4B, ext. Temp sensor, Python…) to control the heating appliance automatically according to the calendar entries. The UI shows past and future events and gives the possibility to modify the automatic settings …
    Your device works like a charm and saves us a lot of heating costs…

    Works well with Bosch CS 7800i LW and was easy to set up. It also works perfectly with the respective ioBroker Adapter.

    I’ve installed two gateways in a hybrid installation (Nefit Enviline & Nefit Topline), both devices report a tremendous amount of data. Together with energy usage from power meters combined into Home Assistant gives me enough information to see whether my installation works efficient.

    Das Gateway ist wirklich ein fantastisches Upgrade für meine Buderus Heizung, innerhalb von wenigen Minuten installiert, eingerichtet und in die Hausautomation (FHEM/mqtt) eingebunden, kein Vergleich zum widerborstigen km200 Gateway (hab ich gleich entsorgt 😉 )

    The Gateway is really an awesome upgrade for my Buderus boiler, installed, set-up and connected to my smart home system (FHEM/mqtt) within a few minutes, no comparision to the flimsy km200 gateway (did throw that away inbetween 😉 )

    Excellent device to integrate my Bosch heatpump with the Loxone powered Smarthome via MQTT. Easy installation inside the controller using the service port and a wired lan connection.

    Super Gerät! Einfach zu installieren, hat auf Anhieb geklappt, Integration In HomeAssistant ebenfalls kinderleicht, habe es schon vielen weiterempfohlen!
    Das Wiki ist ebenfalls sehr gut, es enthält viele gut geschriebene Anleitungen 👍

    Werkt perfect. zo goed als alles ging automatisch hoe het moest. enige dat niet lijkt te werken met mijn setup is warmwaterverbruik (buffer vat, je kan enkel zien wanneer het buffer vat aangevuld wordt, niet wanneer er water uit het buffer genomen wordt)

    Overall, works nearly as described. Unfortuneatly not 100%compatible to the KM Module. I have also few parameters which I’m able to steer with KM Module from Buderus but with the Module E32.

    Inzwischen funktioniert das Gerät perfekt. Wollte es mit der WLAN-Funktion ausprobieren, hat sich auch mit dem Heimnetz verbunden, aber nur eine leere Seite im Browser angezeigt. Die WLAN-Verbindung in den Keller ist allerdings bei mir nicht gut. Als ich dann die Ethernetleitung gelegt hatte, wurde aber alles angezeigt.
    Gibt es eine eigentlich eine Möglichkeit, die Bezeichnungen zu editieren?

    Everything went fine. The device is easy to set up. Boiler is Bosch Condens 2300i with CW400 thermostat. Automation stack: MQTT (Mosquito) + Home Assistant. It works as expected. The device and the firmware are great! Thanks!

    Works as a charm. Provides more parameters then the built in original module. Biggest advantage: it works without cloud. All in my local network.

    Die Einbindung in unser Home-Assistant System mit Buderus GB172 funktionierte schnell und problemlos. Lediglich eine genaue/geschätzte reale Verbrauchsbestimmung ist uns noch nicht gelungen. Hier wäre es schön, wenn bereits im Interface eine Berechnungsgrundlage geschaffen werden würde. An sonsten ist das Interface perfekt.
