Solarman integration for Ethernet LSE Stick Logger

Home Assistant component for interacting with Solarman LSE (Ethernet type) Stick loggers.

Version 99.0.0

Note

BEFORE considering using this add-on :

if you have a LSW (wifi) Stick Logger, this add-on won't work. Please use home_assistant_solarman

if you have a LSE (Ethernet) Stick Logger and a Deye or Sunsynk inverter, you better try first the Sunsynk add-on.

Foreword

I tried the Sunsynk add-on, but I encountered long pauses (10-30 mins) in the data recovery that made the add-on useless. I created a MODS of the old home_assistant_solarman add-on version to support the LSE Stick loggers, but unfortunately, the new version is based on the SolarmanV5 lib and not easy to modify (I'm not a Python developer, just a handyman). I decided to "fork" the excellent home_assistant_solarman project to fit my needs and share it on Github.

The scope is not to maintain a Nth Add-on version but only to share my solution.

This code was developed on a Deye Sun 5K SG03LP1 but could run with other inverters such as SunSynk ones.

Caution

DISCLAIMER: Use at your own and sole risks! Especially when writing any inverter's registers.

Installation

Please refer to the manual installation instructions.

Sorry, HACKS is not supported.

Integration

Solarman LSE uses the same sensors suffix as Home Assistant Solarman, and works well with the nice Sunsynk-Power-Flow-Card below:

You can create your own Card with commands for controlling your inverter (be careful when writing settings because this can irrevocably damage your inverter).

Each command is sent to the invert BUT the corresponding entities will be updated only at the next read (every +/- 1 minute!!!). Don't repeat the command before at least 1 minute.

Here is a Card example for my Deye (create your):

• Time of use on/off aka Scheduling (switch.LSE_time_of_use)
• Priority Load or Battery (switch.LSE_priority_mode)
• Battery Grid Charge enabling (should be enabled to allow grid charge by time slot) (switch.LSE__battery_grid_charge)
• Battery Grid Charge per time slots (switch.LSE_mode_grid_point_1 to 6)
• Battery SOC minimum per time slots (number.LSE_mode_soc_point_1 to 6)
• or write your own automation scripts
• etc.

DEYE Sun 5K

For the Deye Sun 5K inverter owners, you have to:

• Install the Solarman LSE Add-on
• Configure your inverter (Parameters > Devices & Services > Solarman LSE). Select the "deye_sg03lp1_eu.yaml" file. This file is very detailled and has some limitations to avoid wrong data. This could prevent to see the sensors at startup (see Toubleshooting section below)
• Copy the deye.yaml file under /config/packages. This file exposes several additional sensors that you will or not need. Remove the ones unused and create yours using this basis if you need.
• Using Hacks, install the Sunsynk-Power-Flow-Card add-on.
• Create a Card for the Sunsynk-Power-Flow-Card with the correponding sensors
• Create buttons to control the inverter (see the Integration section above for the Switch and Number sensors).

Troubleshooting

• There is no add-on logo but the default icon (sorry).
• Some sensors (or all sensors) show unavailable. In order to avoid erratic data, I setup some INVALIDATE min/max in the Deye inverter definition file. For example, the Total Solar Production cannot be 0 ! BUT when you start for the 1st time or after a inverter reset, the value may be zero and invalidate all or some sensors. If you have problems, comment all the Invalidate field (and min/max value) and full restart H.A.
• Sensor display numeric values instead of state. I have chosen to "interprete" the state within the Cards rather than using the LOOKUP feature in the inverter definition file. It's up to you to re-enable it or create LOOKUP if you need.
• Commands does not work. Did you wait a minute at least after the command? Check the logs (Parameters > System > Logs). Go to the Solarman_LSE integration and enable debugging, send commands and check the logs. You can also issue direct commands (Development Tools > Service then search Solarman LSE service). There are 2 service Simgle and Multiple write. Use single register write to limit the risk and double-check the register address and value for your specific inverter.
