Description
The Gateway E32 V2 (Ethernet + WiFi Edition V2) is the most feauture rich BBQKees EMS Gateway.
It has all the same features as the S3 Gateways and it also has a very reliable BBQKees EMS circuit for all EMS devices, but it comes with an additional Ethernet/LAN connector (and electronic circuitry) for wired networking.
Because the new design did not fit anymore into the existing S3 enclosure, it’s in a bigger case (with mounting holes).
Just plug in the Gateway into the EMS service jack on the boiler or inside the heat pump with the optional EMS service cable and stick it to the side of the boiler. No additional cables are needed and everything is powered from the EMS service jack itself.
If your boiler does not have an EMS service jack or you want to mount the EMS Gateway elsewhere, you can also connect the EMS Gateway in parallel to the thermostat on the EMS screw terminal inside the boiler. In this case the EMS Gateway needs to be powered from the optional external 12V power adapter.
The Gateway connects directly via your home network to your home automation, no cloud, internet service or external accounts needed.
Some key specs:
- New enclosure type with mounting holes
- All connectors one one side
- Circuit board with integrated ESP32 module with future proof 8MB* PSRAM and 16MB Flash
- Robust BBQKees EMS bus circuit compatible with all EMS devices
- Features both LAN and WiFi
- 2.4GHz Wi-Fi (can be turned off when using LAN)
- Reliable 100Mbit Ethernet LAN port for maximum network stability
- Firmware upgrade via the webinterface or USB-C (USB-C port NOT for powering the device)
- Configured for Home Assistant
- Supports the Home Assistant MQTT Discovery protocol
- MQTT Discovery also works with Domoticz and OpenHAB without plugin
- MQTT and Restful API for other interfaces like NodeRED and Loxone
- Telnet console
- Optional DS18B20 temperature sensors
- Powered by service jack or 12V DC power supply
- Connect to the EMS bus via service jack or screw terminal
- EMS-ESP firmware 3.6 and higher
- Supports all EMS heating circuits
- Support large EMS systems with many EMS devices simultaneously
- Support for EMS, EMS+, Heatronic 3 etc.
- CE certified product
New firmware features (available on all EMS Gateways):
- Set virtual remote thermostats for RC30/RC35, RC300/RC310/BC400 main thermostats
- Virtually set the SmartGrid (SG) and PhotoVoltaic (PV) inputs of heat pumps
- Calculate gas/energy consumption in kWh for heating and hot water of all boilers
In the image below a description of all outward facing connectors.
Below an example configuration with LAN cable, EMS via the EMS service cable and an additional DS18B20 sensor.
And here the alternative connection via the orange screw terminal and a 12V DC power supply.
Please check your order to include the EMS service cable or a power supply.
Other jack cables may not fit properly into the connector on the E32 V2. The EMS service cable has special extended plugs.
I also now offer an EMS screw terminal cable which you can include as option with your order or you can find it here.
So if your boiler or heat pump has a service jack, you need the optional EMS service cable.
If your boiler or heat pump does not have a service jack or you do now want to use it, you need the optional power supply and an EMS screw terminal cable.

If you don’t need LAN/Ethernet you can also get a S3 or S3-LR instead. It has all the same features except for the LAN port.
* The hardware already has 8MB PSRAM, the firmware currently supports 4MB PSRAM.
In a future firmware update more can be enabled if needed.
Does not work with OpenTherm or iRT boilers like the Nefit Proline NxT (normal Proline is OK), Nefit Ecomline, Buderus U104, U112, U114, U122, U124, GB112, GB122, Linea Kombi 23. These do not have an EMS bus. Please check before ordering on the EMS device compatibility page.
