Description

The EMS Gateway Premium II kit is the all time bestseller and includes everything you need to add your EMS devices to your home automation system.

Just plug in the device into the service jack on the boiler with the supplied jack cable and stick it to the side of the boiler.
No additional cables are needed and everything is powered from the jack itself or from the EMS bus wires.
Aside from the service jack you can also use the EMS/thermostat wires in parallel to the thermostat.
The Gateway connects via Wi-Fi to your home network.

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

(To make a choice between Gateway models look HERE).
For all EMS 1.0 boilers this product is still good choice, however if you have a heatpump, a newer boiler like the GB192i or 9000i, or a CW400/RC310 thermostat, or you have multiple heating circuits or mixer modules, or you are a ‘power user’, you are better off with the Gateway S32.

Features:

  • Now with the awesome EMS-ESP firmware version V2.2!
  • 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
  • 2.4GHz Wi-Fi connectivity
  • Based on the ESP8266
  • Complete responsive webinterface
  • Firmware updateable via the webinterface
  • Configured for Home Assistant
  • Now supports the Home Assistant MQTT Discovery protocol
  • Plugin for Domoticz
  • MQTT and Restful API for other interfaces like OpenHAB and Loxone
  • Telnet console
  • Optional DS18B20 temperature sensors
  • Supports all EMS heating circuits
  • Support for EMS, EMS+, Heatronic 3 etc.
  • Each product is tested on an actual EMS boiler before shipment

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

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

Power options:

  • Service jack (with the supplied cable)
  • EMS bus/thermostat wires
  • USB adapter (not included)

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 MQTT discovery is available and for Domoticz an easy to use plugin.

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 it gets its power from the bus itself just like a normal thermostat.
In case there are already too many EMS devices on the bus, it can be powered with a USB adapter as well.
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 Premium II
  • Self adhesive/magnetic strip
  • 3,5mm jack cable for the service jack
  • JST cable for connecting external DS18B20 sensors (sensors not included).

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 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 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 without a modification nor is there any support in the firmware.

    As already informed, at the begining it was not working; it was necessary to replace ESP 8266 from inside with another one that I buyed from another shop.
    Just now i consider it a great tool, but for shure is necessary to pay attention when you as company/workshop sell something .

    Great product and very easy installation. Hooked it up to the EMS-Bus via 2-wire.
    I‘m facing some issue on my Buderus RC300 Thermostat now which is showing me the fault code „A11/1037“. This seems to be an issue with the external temperature sensor. This mistake only appears when the Gateway is connected. I checked the wiring and everything is fine. The fault message with the code disapears from time to time for a while and reapears again. I can monitor the mistake on the temperature graph of the RC300. It usually shows a solid line following the outside temperature. With the gateway connected it is interupted (see pictures).
    The gateway itself has no quality losses or mistakes on the EMS Bus.
    The system seems to run smooth and does what it should. But this mistake makes me nervous. Anybody else with a similar issue?

      Reply BBQKees:
      We discussed the problem and it’s a very specific issue with the combination of the GB192i/9000i boiler, a RC300/RC310 thermostat and the Gateway Premium II.
      It was decided that the best solution was to return the product in exchange for the Gateway S32 which does not have this issue.
