My first post was based on the plugin you suggested.waltervl wrote: ↑Friday 09 August 2024 12:15 Perhaps also take a look at this one https://github.com/derenback/Domoticz-SMA-Inverter
Did you try changing your password into something easier? And, are you sure you use the correct password (can you login with the credentials on the SMA directly)? Beware that you only login with the plugin and be logged off from the inverter itself.
Not sure, try?
Wait, is web connect active on the SMA?# Domoticz-SMA-SunnyBoy
Domoticz plugin to get SMA Sunny Boy information
Tested with Python version 3.7 and 3.8, Domoticz versions 4.10717, 4.11799, 2020.1, 2020.2 and 2021.1
## Installation
Assuming that domoticz directory is installed in your home directory.
```bash
cd ~/domoticz/plugins
git clone https://github.com/rklomp/Domoticz-SMA-SunnyBoy
# restart domoticz:
sudo /etc/init.d/domoticz.sh restart
```
In the web UI, navigate to the Hardware page. In the hardware dropdown there will be an entry called "SMA Sunny Boy".
Make sure to (temporarily) enable 'Accept new Hardware Devices' in System Settings so that the plugin can add devices.
Please note you need python dev for the plugin to work To install Python Dev
```bash
sudo apt install python3-dev
```
## Known issues
## Updating
Like other plugins, in the Domoticz-SMA-SunnyBoy directory:
```bash
git pull
sudo /etc/init.d/domoticz.sh restart
```
## Parameters
| Parameter | Value |
| :--- | :--- |
| **IP address** | IP of the SMA Sunny Boy eg. 192.168.1.231 |
| **Password** | password for the User Group, not the Installer one |
| **Query interval** | how often is data retrieved from the SMA |
| **Debug** | show debug logging |

Ah, and are the settings of both exactly the same? Webconnect? Other settings?
