Allows you to connect multiple clients to one single modbus server. Usally one modbus server only allows a single connection and denies any more clients.
The addon is only tested and compatible with hassio supervisor.
- Add This Repository (Or click Button above)
- Install ModBusProxy from the Add-On Store
- Stop all Clients that currently connect to the modbus server. The Server might need some time before another client (our proxy) can connect.
- In case you are using solaredge-modbus in homeassistant you can change the server address here: /config/.storage/core.config_entries.
- Before starting go to the configuration page and set the ip of your modbus server.
- Start The Add-On
- This may take a while on the first start as it builds the cointainer locally. If there is more interest ill switch to prebuild containters.
- Configure Your Clients to connect to your HA IP and choosen port.
- I recommend not to change the listenport in neither the network section nor the listenport.
You can proxy several modbus servers at once. Each device gets its own listen port. Add a devices list in the add-on configuration (YAML mode):
devices:
- upstreamhost: 192.168.1.212
upstreamport: 502
listenport: 502
- upstreamhost: 192.168.1.213
upstreamport: 502
listenport: 503
timeout: 5 # optional, overrides the global timeout
connection_time: 0.5 # optional, overrides the global connection_time
loglevel: INFONotes:
- When the
deviceslist is set, the single device options (upstreamhost,upstreamport,listenport) are ignored. Without adeviceslist the add-on behaves exactly as before. - Each
listenportmust be unique and must also be enabled in the Network section of the add-on. Ports 502 to 510 are available there; map each one you use to the same number as thelistenportof the device.
