# ModbusMQTT # ModbusMQTT
Very rough for now. A bridge between Modbus devices and MQTT.
## Topic spec It is early days, but the plan is:
``` * Support custom Modbus protocols (Sungrow WiNet-S has been implemented)
prefix/status -> { "status": "running" } # last-will message here too * Support _setting_ holding registers over MQTT
* Support optional auto-configuration of Home Assistant entities, including using [MQTT Number](https://www.home-assistant.io/integrations/number.mqtt/) et al for holding registers, to allow setting the value.
prefix/connect/<connection> <- {
"host": "localhost",
"port": 502,
"slave": 1,
}
prefix/status/<connection> -> {
"host": "localhost",
"port": 502,
"slave": 1,
"status": "connected"
}
prefix/logs/<connection> -> { "message": "log message", level: "level" }
prefix/connection/<connection>/monitor[/opt-name] <- {
"address": 5100,
"type": "holding|input",
"count": 1,
"interval": 10, // seconds
}
```
