Be Warned! This Integration has the capability to write modbus data directly to your inverter. I has a very strong possibility to completely brick your device, or at the very least change settings in it which you may not be able to change back, or not know the original value for. Use at your own risk - you have been warned!
This is a Home Assistant component for interacting with Solarman data collectors used with a variety of inverters. The integration allows Home Assistant to connect in direct-mode over the local network to the collector to extract the information, and no cables are required.
It has been tested with a 5kW DEYE/SUNSYNK inverter. The collector is reported to be used in Omnik, Hosola, Goodwe, Solax, Ginlong, Samil, Sofar and Power-One Solar inverters, you may get success from any of these as well.
This component uses version 5 of the communication protocol. If your collector is older and this component does not work, try one of the other integrations that uses version 4 of the protocol.
Feel free to discuss the integration by joining the Discord server.
This method is prefered.
For this, it is highly recomended to use the "Samba share" add-on (you will need to enable advanced mode in your user profile).
Clone or download the repo, and copy the "solarman" folder in "custom_components" to the "custom_components" folder in home assistant.
After that, the folder structure should look as follows:
custom_components
├── solarman
│ ├── __init__.py
│ ├── const.py
│ ├── manifest.json
│ ├── parser.py
│ ├── solarman.py
│ ├── sensor.py
│ └── inverter_definitions
│ ├── parameters.yaml
│ └── custom_parameters.yaml
├── {other components}- Get the IP and Serial Number to use in the configuration.
Find the internal IP of the logger on the DHCP server, and then open a browser and navigate to that address. If you are prompted for a username/password, use "admin" as username and "admin" as password.
Once logged in, expand the "Device information" and note the Device serial number, as well as the IP used.
-
Check the version of the solarman logger. If the serial number starts with 17xxxxxxx or 21xxxxxxx (protocol V5), the component should work. If not, you may need to try the component for V4 of the protocol mentioned above.
-
On your DHCP server, reserve the IP for the WiFi data logger so that it will not change.
This integration can be configured using config-flow, or by manually configuring using the configuraiton.yaml file. Both methods are described below:
- After the installation of this component, click on the "Configuration" tab on the left, then on "Devices & Services"
- Select the "Integrations" tab on the top of the screen, then on the "+ ADD INTEGRATION" button on the left-hand corner.
- Select the solarman integration
4.Configure the entity by filling in the details.
In your configuration.yaml file, add the solarman platform under "sensor"
sensor:
- platform: solarman
name: DEYE
inverter_host: 192.168.0.100
inverter_port: 8899
inverter_serial: 1720747149
inverter_mb_slaveid: 1
lookup_file: deye_hybrid.yaml| Parameter | Description |
|---|---|
| name | This name will be prefixed to all parameter values (change as you like) |
| inverter_host | The IP address of the data logger. (* see: autodiscover) |
| inverter_port | Always 8899 |
| inverter_serial | The serial number of the data collector (* see: autodiscover) |
| inverter_mb_slaveid | The Modbus Slave ID of the inverter. Defaults to 1 |
| scan_interval | Time in seconds between refresh intervals |
| lookup_file | ** The yaml file to use for parameter-definition |
** This parameter is optional, and if not specified will revert to deye_hybrid.yaml. If you customize the parameters, create a lookup file "custom_parameters.yaml" and refer to it so that it will not be overwritten during updates.
| Lookup File | Inverters supported | Notes |
|---|---|---|
| deye_hybrid.yaml | DEYE/Sunsynk/SolArk Hybrid inverters | used when no lookup specified |
| deye_string.yaml | DEYE/Sunsynk/SolArk String inverters | eg. SUN-4/5/6/7/8/10/12K-G03 Plus |
| sofar_lsw3.yaml | SOFAR Inverters | |
| solis_hybrid.yaml | SOLIS Hybrid inverter |
The component has the option to auto-discover the logger IP and serial number.
To use auto discovery, the IP should be specified as 0.0.0.0 and/or the serial as 0
NOTE: This should be used as a temporary or debug measure since the discovery only happens when the component starts and, if the logger is inaccessible at that point, the entities will unavailable until restart. This will not be the case when the IP and serial was specified.
sensor:
- platform: solarman
name: DEYE
inverter_host: 0.0.0.0

Once the component is running, it will add the following entities to Home Assistant
Apart from the inverter-parameters, it will also add status entities to view the status of the solarman component.
The entities includes the device classes to enable it to be added to the Energy Dashboard introduced with Home Assistant Core 2021.8.
To configure the energy dashboard with the infirmation provided by this component, see configuring energy dashboard
This integration was tested agains the DEYE 5kW inverter, and it is possible that the parameter-definitions for other inverters may differ. If you want to try your hand at it, refer to customizing parameters.yaml
