EV Meter via MQTT -> Home Assistant

[adjego]

I have installed an EV Meter and connected it to the SmartEvse. All is shown on the webpage and in the MQTT data this information is in. Is there a way to have this EV related data also to show up in Home Assistant?

I installed SmartEVSE-3 integration in HA.

But some sensors didn't work. Cause could be that I have the Eastron SDM630 for EVSE not connected to the Smart EVSE. The kWh-meter shares the Modbus gateway with 5 other Eastron kWh-meters.

I notice that a few / some topics from the Smart EVSE in MQTT do not relate to the sensors of the integration in HA. Cannot explain why the differ... I rearranged that myself. So there is still some work to do yourself.

The HA integration is deprecated, use the MQTT integration instead.

Modbus only allows 1 master device on the modbus, and this should be SmartEVSE.

If another device is master on the modbus, have that device send its info via MQTT to HA. and feed SmartEVSE via MQTT API. Details are in the online manual.

Thnx for quick reply. I read on this page: https://github.com/dingo35/SmartEVSE-3.5/tree/master/integrations there was an deprecated version. But there was no link to a new solution for that.

Sorry to say that I cannot find info how to implement another dashboard with info from my smart EVSE in HA. The link in the online documentation that I found leads to forms with a wood of questions.. Maybe because of autodiscover?

In MQTT Explorer I see that de controller sends its topics. If I make sensors for the smart EVSE in HA they are updated..
But if I do it through the wizard I miss information to fullfill the wizard.
For instance: What type of entity?
And later on I have to fill in a template...

It ends up like this:

Any help, like a link to the correct info, is appreciated. Thnx in advance.

It should detect the SmartEVSE automatically, when you check your MQTT devices.

After selecting one SmartEVSE, you are presented with all the sensors:

Thnx for nice screenshot. But it didn't really help me further to install it in my HA.

Does that mean that it uses AutoDiscover from HA? In my case the device does not show up in the MQTT integration nor there entities.. Only entities I made manualy for the Smart EVSE in mqtt.yaml, based on shown topics in the broker, refresh their data... So the connection is there.

Had in mind the software of Smart EVSE works with Auto-Discover but there is no discovery‑topic like topic homeassistant/..../config

I deleted the HACS integration. Rebooted my HA server but no new devices. Not even the Smart EVSE. Running the latest version of HA. This version should support AutoDiscover..

Where in the documentation can I find info to install this dashboard?

You are aware you need to run an MQTT broker? Google is your friend...

[ZonPV]

Well, sometimes you can search for ages...
The solution is unknown, but EITHER rebooting the Synology device running the broker OR updating HA to V 26.2.0 caused the Smart EVSE to appear in the MQTT integration.

Thanks everyone for their input.
