S0 Gateway

Monitor energy consumption of S0 meters

Measure real-time energy consumption

The S0 Gateway makes your intermediate meter with S0 pulse connection smart. It gives you live insight into energy consumption. This way how you know exactly how much energy you are using or feeding back to the grid

3D view

Beautiful dashboards

Energy consumption is shown in beautiful dashboards, giving you more insight into consumption or production of solar panels. So you can use it with the Home Assistant energy dashboard, Homey and Domoticz. You also get exclusive access to the Smart Gateways S0 Gateway Dashboard for Home Assistant where you can see even more data.

Easy to install

The S0 Gateway works with most intermediate meters. In fact, intermediate meters often have an S0 connection that pulses during consumption or return of energy. The gateway is suitable for measuring energy from meters of the Siemens, ABB, Landis+Gyr, Iskraemeco, Kamstrup, EMH metering and Schneider Electric brands .

Suitable for almost all Home Automation software

The S0 Gateway is compatible with virtually all Home Automation software such as Home Assistant, Domoticz and has its own Homey app.

You’ll find a big collection of manuals on our support page.

Open Standards

By using open standards such as REST API and MQTT, the S0 Gateway can interface with virtually any software. So you can use your own cloud service. With MQTT support via TLS encryption, data transmission meets the highest standards.

Suitable for most intermediate meters

Most intermediate meters have a two-wire connection that pulses during operation. This connection, also called DIN EN 62053-31 connection, can be connected to the S0 gateway. You can find in the manual of the intermediate meter if it has a S0 pulse connection, often marked 1000imp/kWh as shown in the picture below. If in doubt, feel free to contact us using the contact form below.

Can I track my energy consumption in real time?

Of course! The S0 Gateway continuously reports energy usage so you can always see what your usage is.

Can I use the S0 Gateway even without home automation software?

As with all our gateways, you can subscribe to the Online Energy Dashboard. You can choose this option at checkout. You can decide later, of course.

Yes, the cable from the S0 gateway to the intermediate meter can be extended up to 15 meters. The gateway has screw terminals used to attach the sensor. This can be done with “thin speaker cable” of 0.5mmΒ² or 20AWG”

You can also use the S0 Gateway without home automation. This can be done with a subscription to our online dashboard. You can select this when adding the gateway to your shopping cart.

You can use your own sensor or the one that comes with the intermediate meter. Make sure your sensor operates at a voltage between 0 and 36V. NO (Normally Open) and NC (Normally Closed) are supported.

You receive a manual with the S0 Gateway that allows you to quickly start monitoring energy consumption. On our support page, you’ll find detailed guides for using various types of home automation software.

Yes, you can. The Online Energy Dashboard works independently of other integrations.

Of course. The S0 Gateway tracks hourly, daily, monthly and yearly consumption for easy comparison.

Yes, this is possible. For example, you can connect your gateway to Domoticz, Homey, and Home Assistant, while also viewing usage through the Online Energy Dashboard.

You can choose to block internet access. The Gateway will still work without an internet connection. Of course, you will need internet access for OTA firmware updates.
