Thank you, looks promosing.

Can not get the OpenEVSE to connect 'Entramos en nuestro OpenEVSE por IP'
https://domotuto.com/integracion-domoti ... evse-mqtt/: after clicking 'saved' in http://192.168.0.xxx/#services it says 'Connected: NO'
Do I need to activate some general MQTT service in domoticz first or just installing your plugin?

2) Domoticz side: what is the port number in the hardware settings? Can not check it in OpenEVSE. I assume '1883' is default?

[renerene]

additional to post above.
maybe this is the cause:

2) found out that 1883 is default port for OpenEVSE, so question 2 is answered.

Success!

Turned out you need to install mosquitto first.
http://mosquitto.org/blog/2013/01/mosqu ... epository/

Code: Select all

sudo apt-get update
sudo apt-get install mosquitto

[ayasystems]

Sorry for delayed answer and thanks for your feedback

I can see that you have it working now...!

Regards!

Hello, with a fresh install of Domoticz on Bullseye, and after following the git clone steps with domoticz restart, the "OpenEVSE mqtt plugin" hardware type is not showing in the pull-down list on the domoticz hardware section.

Folder /home/pi/domoticz/plugins/OpenEVSEPlugin/ is created and has 5 files
Any ideas?

My Domoticz version:
Version: 2022.2
Build Hash: eea9db734
Compile Date: 2022-11-05 13:05:35
dzVents Version: 3.1.8
Python Version: None

[waltervl]

Any ideas?

Python Version: None

You do not have Python installed (correctly) on your server.
Check wiki page https://www.domoticz.com/wiki/Using_Python_plugins

[renerene]

yes, there was a problem with Python. Thank you. Plugin now avaulable.
Still not working. Temperature sensor is updated at domoticz startup time, but value is wrong and no temp updates

Maybe it would be an idea to do the documentation in English?
The main page says ESP322 ... Does this exist? Could be my French

[renerene]

ah, finally got my temperature working

Tips:
1) https://www.domoticz.com/wiki/MQTT#Architecture
Warning: from Mosquitto v2.0.x you need extra configuration, else no connection is made with Domoticz see also viewtopic.php?f=28&t=35706
To see your installed version:
mosquitto -h | grep version
To fix this edit the /etc/mosquitto/mosquitto.conf file and add:
listener 1883
allow_anonymous true

2) check if your MQQT commands are coming in:

Code: Select all

pi@raspberrypi:~ $ mosquitto_sub -v -t OpenEVSE/#
OpenEVSE/amp 7480
OpenEVSE/wh 18480341
OpenEVSE/temp1 132
OpenEVSE/temp2 -2560
OpenEVSE/temp3 -2560
OpenEVSE/pilot 8
OpenEVSE/state 3
OpenEVSE/freeram 26984
OpenEVSE/divertmode 1

3) modify aroud line 140 in /home/pi/domoticz/plugins/OpenEVSEPlugin/plugin.py "temp" --> "temp1":

Code: Select all

              #modified 2022-12-27 , see https://www.domoticz.com/forum/posting.php?mode=reply&t=32189
              #OLD: if (mqttpath[1] == "temp"): 
              if (mqttpath[1] == "temp1"):
                unitname="Temp"
                subval="temp"

Could you help to make an English documentation? Any help is welcome

[gizmocuz]

Could you help to make an English documentation? Any help is welcome

I think everyone creating software (c++/vb/scripts) should program in English

For example, there are some great open-source projects in Chinese, Zulu, French ....

But that's just my 2 cents

[ayasystems]

Could be better collaborate than request. working together

[waltervl]

Problem is that our Spanish is not that well...
You can try to use the google page translation module on your website to have google translate it for you. There are wordpress plugins for that.
For the github page you can have google translate do the basic translation for you and you can fine tune it.

[ayasystems]

You also can use the google translate ... Sorry man.

Indeed, but if you want a bigger audience for your hard work creating a nice plugin we only advise you to create an English manual. We cannot help (as being Dutch) because we are not good enough in Spanish language.

[ayasystems]

People want things without contributing anything. Only 3 stars on git hub. My English is also not good enough to do documentation, so I need help for it.

Mensen willen dingen zonder iets bij te dragen. Slechts 3 sterren op git hub. Mijn Engels is ook niet goed genoeg om documentatie te doen, dus daar heb ik hulp bij nodig.

Hi
Is it possible with your plugin to limit the charging current, so that I can use the surplus power from the solar system to charge the electric car? Is it possible to switch between single-phase and three-phase charging?

@all: nowadays translation is easy with Chat-GPT

[ayasystems]

I don't have time and I'm not going to make any more improvements to the plugin. What has been done is a good starting point for someone to improve and add things
