A small update...
As I am a noob with Python language.. I got lost about the command
Code: Select all
Devices[2].Update(0,str(Total_kWh))
Environment:
SDM630-Modbus V2 together with a USB to RS485 Adapter - CH340
I changed the SDM120-Modbus software
Raspberry Pi 4 - 4GB.
OS: Raspbian GNU/Linux 11 (bullseye)
Python 3.9.2.
Domoticz Version: 2023.2 (build 15459)
I prefer in the GUI a device with the type of Managed Counter. Or General, kWh. It should show a bar for every different day. A line graph is less readable...
But not the results I expected.
So I tried 3 different sort of devices from the list in the Wiki:
https://www.domoticz.com/wiki/Developin ... vice_Types
But not always input from the plugin to the devic in Domoticz
The device with IDX 1, SubType kWh, is updated but has no data in graph.
The device with IDX 2, custom sensor, is updated and had data in graph.
The device with IDX 3, Managed Counter, is not updated
This is my script: Original authors still readable
Code: Select all
#!/usr/bin/env python
"""
Eastron SDM120-Modbus Smart Meter Single Phase Electrical System. The Python plugin for Domoticz
Original Author: MFxMF and bbossink and remcovanvugt
Better Error handling and event recovery added by simat-git 2023.
Edited by PieterS for Eastron SDM630
Works with Eastron SDM120M / SDM120CT-M, can be easily adapted to any Modbus meter.
Requirements:
1.python module minimalmodbus -> http://minimalmodbus.readthedocs.io/en/master/
(pi@raspberrypi:~$ sudo pip3 install minimalmodbus)
2.Communication module Modbus USB to RS485 converter module

In my opinion it has to do with the command
#Update devices
Devices[2].Update(0,str(Total_kWh))
Devices[3].Update(0,str(Total_kWh))
Devices[4].Update(0,str(Total_kWh))
I do not understand what is wrong.
3 different devicetypes, 1 command should do the job? No errors in the logfile of Domoticz.

Any help appreciated. Did not find info on the wiki about the syntax how update a device..
Thnx in advance!
