The go-eController has a Modbus TCP Interface an which can be used to read some power and energy values. This interface has to be enabled from the app or the http API.
Live Values can be received with Modbus function 4.
Settings can be read with the Modbus function 3 and can be written with the Modbus function 16.
After enabling the tcp port 502 is used.
| Function No | Name | Supported? |
|---|---|---|
| 01 | Read Coil Status | No |
| 02 | Read Input Status | No |
| 03 | Read Holding Registers | Yes, for all registers listed below |
| 04 | Read Input Registers | Yes, for all registers listed below |
| 05 | Force Single Coil | No |
| 06 | Preset Single Register | No |
| 15 | Force Multiple Coils | No |
| 16 | Read Input Registers | Yes, for all registers listed below |
Tap the tab "Internet" at the bottom, then click on "Advanced Settings" in the menu, then at the very bottom "Modbus"
The chargers provide api keys to configure and verify the modbus interface. These api keys can be used with the http api.
Example: http://192.168.0.77/api/set?men=true
| api key | description | datatype | R?W? | Category |
|---|---|---|---|---|
| men | modbus slave enabled | bool | R/W | Config |
| msp | modbus slave port (requires reboot) | uint16 | R/W | Config |
| msb | modbus slave swap bytes | bool | R/W | Config |
| msr | modbus slave swap registers | bool | R/W | Config |
| mro | modbus slave read operations | size_t | R | Status |
| mwo | modbus slave write operations | size_t | R | Status |
Data in this table can be read with modbus function 04.
