Discontinued. New Gateway S3 version available now. 

If your boiler has a service jack you do not need the DC power supply, only the jack cable.
If your boiler does not have a service jack, or it does but you want to mount the Gateway elsewhere you need to get the version with the DC power supply. Both the service cable and the power supply are sold separately as an option below.

Discontinued. New Gateway S3 version available now. 

This ESP32 based Gateway S32 (Standard Edition V2.0) is the only device you need to add your EMS devices to your home automation system.

Just plug in the device into the service jack on the boiler or heat pump with the optional jack cable and stick it to the side of the boiler.

If your boiler does not have a service jack, you can also use the EMS/thermostat wires in parallel to the thermostat.

No additional cables are needed and everything is powered from the jack itself or from an external 12V power adapter.

The Gateway connects via WiFi to your home network.

Its all neatly packed in a nice and small enclosure (90x50x24mm) that fits into your hand.

(To make a choice between Gateway models look HERE)


  • 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
  • V2.0 circuit board based on the Espressif ESP32 with 16MB flash
  • 2.4GHz Wi-Fi connectivity
  • EMS-ESP firmware V3
  • Complete responsive webinterface
  • New: English, German, Swedish, Polish and Dutch language selection (more to come)
  • Firmware upgrade via the webinterface
  • Configured for Home Assistant
  • Supports the Home Assistant MQTT Discovery protocol
  • MQTT Discovery now also works with Domoticz without plugin
  • MQTT and Restful API for other interfaces like NodeRED, OpenHAB and Loxone
  • Telnet console
  • Optional DS18B20 temperature sensors
  • Supports all EMS heating circuits
  • Robust third generation BBQKees EMS circuit design with 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 optional cable)
  • 9-12V DC (with the optionally supplied power adapter)

If your boiler has a service jack you do not need the DC power supply, only the jack cable. If your boiler 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.

Do not use cheap audio cables for the service jack as they have very thin wires inside. Only use the optional 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.

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 power supply.

Because the Gateway is an ‘always on’ device it contains high quality components like Panasonic and Murata capacitors for maximum longevity of the device.

Included in the kit:

  • Fully assembled and tested Gateway S32 (Standard edition)
  • Self adhesive strip
  • JST ZH cable for connecting external DS18B20 sensors (sensors not included).
  • Optional: 3,5mm jack cable for the EMS service jack
  • Optional: 2-pole Euro plug power supply with 12VDC output and 5.5mm DC barrel jack connector (center pin positive).
  • Optional: wall mount bracket.

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.

    De Gateway was makkelijk te installeren met de documentatie op de wiki. Ik heb het gekoppeld aan Home Assistant via de MQTT integratie. Het zou fijn zijn als MQTT niet per se nodig is. Het is nu het enige apparaat wat dit bij mij gebruikt. De S32 werkt heel stabiel met mosquitto 2.0.12. Ik had wel problemen met een 1.x versie van mosquitto. Nadat ik de nieuwere versie ben gaan gebruiken, heb ik geen problemen meer gehad. De integratie met Home Assistant werkt ook prima. Ik heb een thermostaat widget en notificaties ingesteld als de temperatuur gewijzigd wordt. Deze worden vrijwel direct verstuurd na een wijziging.

Het enige dat niet helemaal werkte was de naamgeving van de variabelen in Die blijken in werkelijkheid allemaal met kleine letters te zijn geschreven en niet zoals in de plugin met een combinatie van grote en kleine letters. Kleinigheid, snel opgespoord met MQTTExplorer en aangepast. Loopt nu als een trein. Bedankt Kees!

    I had actually ordered the Gateway S32 and received instead the E32 upgrade. Installation was a little more complicated for me because my boiler did not have a service jack; I had no power socket nearby; I wanted to enclose both EMS Gateway and 12V DC transformer in a neat, waterproof case and; I wanted to use the opportunity of a 12V DC power supply to connect a z-wave device and strengthen the z-wave mesh in that part of the house. It all worked great, thanks to the continuous advice of Kees at BBQKees Electronics

    The EMS-ESP appears well constructed. Following the instructions, it was easy to get it connected to my boiler (WB Greenstar Heatslave II) and MQTT broker. The extensive information and control afforded by the gateway has allowed me to significantly improve the integration of my central heating system with our home automation platform.

    Next step: When Lenovo IdeaPad Duet 3 x86 tablet arrives, install Debian on it and run Home Assistant Supervised on it and use it as a wall-mounted controller – for EMS ESP, among other things.

    Das Gerät wurde mit dem beigefügten Audio-Kabel am Service-Stecker angeschlossen und lief sofort. Die Grundeinstellungen waren schnell erledigt: Einbinden ins Netzwerk und anpassen MQTT. Die Komponenten der Anlage wurden sofort erkannt und die Werte angezeigt. Natürlich muss man sich zunächst einlesen, weil die Fülle der Informationen sehr groß ist. Die Einbindung in ioBroker war mit Hilfe des Adapter ebenfalls sehr einfach.
    Inzwischen logge ich eine Reihe von Werten in der Hoffnung, dass ich die Anlage optimieren kann. Bei den heutigen Gaspreisen eigentlich ein Muss.
    Dank an Kees für die für das wirklich hilfreiche Gerät und natürlich an die vielen Entwickler, die das Protokoll geknackt und dokumentiert haben und und die tolle Software geschrieben haben!

    Ich habe das Gateway in einer Buderus Logamax plus GB152T mit Solarthermieanlage eingebaut. Alle Komponenten wurden sofort erkannt und konnten problemlos ausgelesen und in iobroker eingebunden werden. Mit Hilfe eines Dashboards in Grafana habe ich sehr gut nachvollziehen können wie meine Heizung funktioniert und diese optimieren können. Ohne das BBKees Gateway und die wirklich sehr gut funktionierende EMS-ESP Firmware wäre das niemals möglich gewesen.

    Mein Ziel war es eigentlich nur die Heizung unkompliziert vom Smartphone an und abzustellen. Nun kann ich viel mehr und beispielsweise die Warmwasserbereitung nur bei Bedarf aktivieren. Gerade im Zusammenspiel mit einer Solaranlage lässt sich hier eine hohe Energieersparnis erreichen in dem die Mindestwarmwassertemperatur Mittags heruntergeregelt wird und die Solaranlage schneller in Anspruch genommen werden kann.

    Mein einziger Kritikpunkt wäre, dass die Parameterbezeichnungen in der EMS-ESP Firmware teilweise eine weiterführende Erläuterung gebrauchen könnten. Man kann es sich aber auch selber herleiten wenn man die Werte eine Weile überwacht.

    Ich kann das Gateway jedem nur empfehlen und habe es auch schon im Bekanntenkreis weiterempfohlen. Es ist gut verarbeitet und sehr einfach zu installieren.

    Connected to Home Assistant via MQTT – 208 entities

    I am able to measure the production of thermal energy.

    After a week of daily logging of gas consumption and data from the S32, I am now able to measure gas consumption directly from the data from the S32. The deviation is ± 2%.
    It works very well in my case.

    Here is my sensors template

    – sensor:

    – name: “Gas Energy”
    unit_of_measurement: “kWh”
    device_class: energy
    state_class: total_increasing
    state: >
    {% set total = states(‘sensor.gas_consumption’) | float(0) %}

    {{ (total * 10.69) | round(3) }}
    icon: >

    – trigger:
    – platform: time_pattern
    seconds: “*”
    – name: “Gas Consumption”
    unit_of_measurement: “m³”
    device_class: gas
    state_class: total_increasing
    state: >

    {% set old = states(‘sensor.gas_consumption’) | float(0) %}
    {% set new = states(‘sensor.boiler_burner_current_power’) | float(0) %}

    {{ (old + new / 169000) | round(9) }}
    icon: >

    Thank you so much for this great product

    The product looks very good. Instalation was easy. I have a boiler Buderus Logamax Plus GB062 – 14 with thermostat RC310. (direct conection to connector together with thermostat) I operate this gateway with Home Assistent via MQTT broker. Autodetection works perfectly. Now I can see all sensors in Home Assistant and I can change setup of RC310 (for example, I can change program from Heating to Reduce mode after leaving home, automatically based on another sensor in home Assistant)

    Produkt rewelacyjny, podłączony do Buderus LOGANO PLUS. Działa super, integracja z Homeassistantem bezproblemowa. Jestem pod wrażeniem wykonania zarówno sprzętowego jak i oprogramowania które zarządza interfejsem.Instalacja bezproblemowa.

    The gateway exceeds my expectations. Works like a charm, detected everything in the blink of an eye. Monitoring is spot-on and I am able to control my heater from everywhere in the world. I use home assistant as a smart-home platform and the integration via MQTT discovery couldn’t be any better.
