This is done by reading the active power at the meter which should be connected just after your main electricity meter, and throttling the generation of your inverter whenever required. text/html 2021-11-12T10:30:54+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.wattmon.com/dokuwiki/how_tos/export_to_custom_server?rev=1636713054&do=diff Exporting Data to a Custom Server The Custom Data Export allows you to push data to your own server at an interval of your choice. You need to specify the URL of the script on your server that can handle the incoming data and respond with an appropriate success or failure message. text/html 2025-01-08T10:50:32+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.wattmon.com/dokuwiki/how_tos/mqtt_app_commands?rev=1736333432&do=diff /device/tx/0 - update data in an existing device 0 Payload: comma separated data register values to be updated DEVID/app2wm/modbus/tx/0 - send data on modbus 0 Payload - hex bytes 00112233AABBCC Response data: DEVID/wm2app/response/modbus/rx/0 Data: Hex bytes from modbus channel text/html 2024-04-05T05:05:21+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.wattmon.com/dokuwiki/how_tos/mqtt_configuration?rev=1712293521&do=diff MQTT Configuration As of Firmware x.1311 onwards, we have added several more MQTT configuration parameters that can currently be configured through the INI located in /config/mqtt.ini.

The device is configured by default for RS-232 voltage levels and by using a simple DB9 cable can be connected to any serial device. For specific devices that require TTL levels, a jumper setting inside the device can bypass the level converter IC and it can thus be used to interface with sensors or other devices at 3.3V DC.
