Integrations with other systems.

CEMM 3.0 can read data from various meters or systems. Conversely, CEMM 3.0 can also share data in multiple ways. This allows CEMM 3.0 to be integrated into Home Assistant or, for example, into an existing building management or energy monitoring system.

MQTT

Send or receive real-time data via MQTT and integrate CEMM into your existing home automation system.

Webhooks

Have your CEMM 3.0 send data to a web server or PVOutput.org at a chosen interval.

Public API

The public API allows data to be retrieved from the CEMM via the local network.

DSMR Output

CEMM 3.0 can create and forward P1 messages, even if a smart meter is not present.

MQTT Broker

MQTT

CEMM 3.0 can publish data to an external MQTT broker. This allows you to share data with other applications, including Home Assistant. You have complete freedom in choosing which data is shared. With the optional MQTT Monitoring module, CEMM 3.0 can also receive data via MQTT.

All about MQTT

Publish

Have your CEMM automatically send data to an external MQTT broker. This can be real-time values, but also monthly totals, for example.

Home Assistant Discovery

Use this ready-made connection to let your CEMM share all relevant energy data with Home Assistant.

MQTT Monitoring

With the optional "MQTT Monitoring" software module, your CEMM can also receive data via MQTT. For example, from a battery system, inverter, or charging station.

Webhooks

With Webhooks, you can send your CEMM energy data directly to a specified URL. You can also set the interval. A ready-made connection to PVOutput.org is included as standard in every CEMM. Want complete control? Then use the optional Webhooks module.

PVOutput.org

With the built-in PVOutput.org option, your CEMM can send all the necessary data to PVOutput.org with just a few clicks. No complicated configuration required.

HTTP Post Request

The Webhooks module allows you to use data from the CEMM in other systems. The data is sent directly from the CEMM to the URL you specify as an HTTP POST message.

CEMM API output

Public API

The public API allows you to retrieve data from the CEMM. This includes not only real-time power, but also historical consumption and meter readings. The API is available to anyone with local access to a CEMM.

DSMR Output

With the optional DSMR Output module, CEMM 3.0 can generate and send P1 messages, even if a smart meter is not present. This is ideal for load balancing a charging station, for example.

With and without smart meter

Are you reading your main connection with a Modbus kWh meter, for example? You can also generate CEMM P1 messages for your other devices that only work with the smart meter.

Full control

You choose which meters are used as a source for the P1 messages.
