Description

As the successor of the ESP8266 based Gateways, the new ESP32 based Gateway S32 (Standard Edition) kit 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.
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 Wi-Fi to your home network.

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

(To make a choice between Gateway models look HERE)

Features:

  • 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
  • 2.4GHz Wi-Fi connectivity
  • EMS-ESP firmware V3
  • Complete responsive webinterface
  • Firmware updateable via the webinterface
  • Configured for Home Assistant
  • Supports the Home Assistant MQTT Discovery protocol
  • Plugin for Domoticz
  • MQTT and Restful API for other interfaces like NodeRED, OpenHAB and Loxone
  • Telnet console
  • Optional DS18B20 temperature sensors
  • Supports all EMS heating circuits
  • Support large EMS systems with many EMS devices simultaneously
  • 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 supplied cable)
  • 12V DC (with the optionally supplied power adapter)

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

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 you need to use the 12V adapter.
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/magnetic strip
  • 3,5mm jack cable for the service jack
  • 12V DC power supply with 5.5mm DC barrel jack connector (center pin positive).
  • JST ZH 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.

Note:
If you are looking for an Ethernet Gateway model: It’s under development and expected around the end of Q2 2021.
(It will be a bit more expensive, because it will have much more components.)
