Sharing my experience integrating a Victron NS EV charger to Home Assistant using Modbus TCP, without a GX controller.
Credit to Sascha Bajonczak, who posted about integrating charging point metrics in Home Assistant with Modbus, which helped me significantly in drafting this configuration.
Also thanks to VincentVreeburg who posted their config on the Victron Community that helped guide me with this project.
Victron publish the Modbus TCP Register list on their website, which I used to obtain the relevant modbus addresses. They also have a PNG image of the charger unit on their site that with looks great with the charger-card lovelace card available through HACS (sorry for no links - limited as new user!).
It is worth noting that while this is a 3 phase 22kw charger, I am using this in single phase mode. If you are using the full three phases, itās likely that you will need to use a different modbus address to obtain the power value (likely 5014 - Total power).
So first, the modbus configuration to obtain the values from the EVSE:
modbus:
- name: VictronEVSE
type: tcp
host: 192.168.x.x
port: 502
delay: 5
message_wait_milliseconds: 30
timeout: 5
sensors:
- name: "EVSE_ChargeMode"
data_type: uint16
input_type: holding
address: 5009
scan_interval: 10
- name: "EVSE_ChargingActive"
data_type: uint16
input_type: holding
address: 5010
scan_interval: 10
- name: "EVSE_L1PowerUsed"
data_type: uint16
input_type: holding
address: 5011
scan_interval: 10
- name: "EVSE_ChargerStatus"
data_type: uint16
input_type: holding
address: 5015
scan_interval: 10
- name: "EVSE_ChargeCurrentActual"
data_type: uint16
input_type: holding
address: 5018
scan_interval: 10
- name: "EVSE_SessionTimeL"
data_type: uint16
input_type: holding
address: 5020
scan_interval: 10
- name: "EVSE_SessionEnergy"
data_type: uint16
input_type: holding
address: 5021
scan_interval: 10
switches:
- name: "EVSE_StartStopCharging"
address: 5010
command_on: 1
command_off: 0
scan_interval: 10
verify:
input_type: holding
address: 5010
state_on: 1
state_off: 0
This obtains all the key values that I saw as useful, when compared to the native bluetooth application provided by Victron.
So these were in a more useful format and available via a single helper, I created the following sensor:
sensor:
- platform: template
sensors:
evse:
friendly_name: "Victron EVSE"
unique_id: EVSE
value_template: >-
{{ states("sensor.EVSE_ChargerStatus") }}
attribute_templates:

{% set status = states("sensor.EVSE_ChargingActive") %}

{{(states("sensor.EVSE_L1PowerUsed") | float) *0.001}}

{% endif%}

Charge_Current_Actual: >
{{(states("sensor.EVSE_ChargeCurrentActual") | float) *0.1}}
Session_Time_L: >
{% set total_seconds = states("sensor.EVSE_SessionTimeL") %}
{% set hours = (total_seconds|int // 3600) %}
{% set minutes = (total_seconds|int % 3600) // 60 %}
{% set seconds = (total_seconds |int% 60) %}
{{ '%02d' % hours }}:{{ '%02d' % minutes }}:{{ '%02d' % seconds }}
Session_Energy: >
{{(states("sensor.EVSE_SessionEnergy") | float) *0.01}}
I was then able to use these values with the lovelace charger card:
type: custom:charger-card
entity: sensor.evse
brand: template
show_leds: false
details:
status:
entity_id: sensor.evse
attribute: Charger_Status_Text

show_name: true
show_status: true
show_stats: true
show_toolbar: false
show_collapsibles: false
compact_view: false
grid_options:
columns: full
Iām pretty happy with the end result. Itās worth noting the switch tile below the charger card can only be used to āstopā the charging session when in Scheduled mode. I havenāt tested this in other modes as yet, but assume in Manual mode it will allow starting and stopping of charging.
Hope this helps others with integrating this EV charger into your Home Assistant environment!
