RESTful API¶
![Restful API logo](../_images/rest-api-icon-blue2.jpg)
The Gateway communicates via MQTT and publishes and listens to a number of topics.
However as of firmware V2.1 a new RESTful API is available. This means you now can send HTTP commands like
http://ems-esp/api?device=<device>&cmd=<command>&data=<data>&id=<id>
See Proddy’s EMS-ESP Wiki 1 for all the details on the API.
For EMS-ESP32 there is also a new, more powerful API V3 available.
