Check address 791. My guess is that if it returns 1 (voltage/current limited) this should denote the MPPT is being throttled and not producing at full power.
Ok I now have Solar Power in Watts.
Buy how do I add this to my energy dashboard?
Ik meen dat je het grid setpoint een waarde geeft dit is dus in jouw geval ook voor 3 fase
Hi @kc_au
Thanks you for your awesome guide (itâs working fine also with my installation) !
Did you also setup an energy dashboard. In my setup, the battery and the solar production are missing, you to ?

Dear @kc_au
Thank You VERY MUCH for your explanation⌠I have integrated my Multiplus 2 with your code !
I try desperately to monitor the US3000C Pylontech Temperature Battery in my HA OS ⌠So I think it is very important to monitor the temperature of Pylontech batteries with HAOSâŚ
Could you give me the Modbus adresse from it please ?
#Battery
- name: âAverage Pylontech Temperatureâ
unit_of_measurement: â°Câ
slave: xxxx #HUB
address: yyyy
data_type: int16
scale: 0.1
precision: 0
device_class: temperature
Best regards
Alexandre from France
from the excel if your battery is available on the hub i think this would work:
#Battery
- name: âAverage Pylontech Temperatureâ
unit_of_measurement: â°Câ
slave: 100
address: 61
data_type: int16
precision: 1
device_class: temperature
Iâm really struggeling to get the âsensor.power_load_no_var_loadsâ to working.
this is what my template sensor looks like:
- sensor:
- name: "Power load no var loads"
unique_id: fbfeef21-1aa3-4a54-b781-426f46fef597
unit_of_measurement: "W"
device_class: power
value_template: >
{% set powerload = states('sensor.victron_grid_load') | float(default=0) %}
{{ powerload }}
EMHASS shows this in the logs:
ERROR - Variable sensor.power_load_no_var_loads was not found. This is typically because no data could be retrieved from Home Assistant

Please, advise on how your EMHASS sensor looks like.
did you have any luck with my suggestion?
Thanks. Works great for me as MQTT is so unreliable
Regarding the initial post, Automation 2+3 can be done with just one single action, using this value-assignment:
value: "{{ ( states('input_number.input_current_slider') | int + 2**16 ) | int % 2**16 }}"
Hello, sorry but can someone please tell me where the error is.
I only get straight values ââreturned,
Multi shows e.g. 233W, I get 230.0 displayed, always rounded.
- name: 'Victron Inverter AC IN L1 W'
unit_of_measurement: "W"
slave: 227
address: 12
# scan_interval: 5

I would like to read out the performance of the AC-1
Hi Everyone
Followed your guide, thanks so much got sensors to work,
I have two questions.
I cant seem to add the solar sensor to the solar panels any idea on this? Also it is in Watts and HA needs it to be in GJ, kWh, MJ, MWh, Wh.
And how do i combine Victron energy from Grid op phase 1,2 & 3?
Thanks in advance!
Any experience with the HACS integration in HA for victor GX??
Hi, you have to create a new Helper in /config/helpers like
{% set l1 = states('sensor.victron_system_grid_l1') | float %}
{% set l2 = states('sensor.victron_system_grid_l2') | float %}
{% set l3 = states('sensor.victron_system_grid_l3') | float %}
{{ (l1 + l2 + l3 ) | float }}
Sensors are coming from GitHub - sfstar/hass-victron: Integration for Home Assistant to fetch data from the victron gx device via modbusTCP integration.
And then use this new sensor in HA Energy dashboard setup.
Hi everybody. i was reading this post and also starting with modbus in homeassistant. according to my experience, it is better to switch to mqtt, where it is possible to control it fully than at the modbus level. modbus lost my connection under certain conditions
configuration.yaml
mqtt: !include_dir_merge_list mqtt/
create âmqttâ dir in file editor
open it
create file âbinary_sensor.yamlâ
- binary_sensor:
state_topic: 'N/***yours_victron_id***/vebus/276/Leds/Absorption'
name: 'Led Absorption'
unique_id: 'vebus/276/Leds/Absorption'
payload_on: "1"
payload_off: "0"
value_template: '{{ value_json.value | int }}'
device: {
identifiers: [
"Multiplus-II"
],
manufacturer: "Victron Energy",
model: "48/3000/35-32",
name: "Multiplus-II"}
I can provide the entire code if anyone wants

add to the sensor
device_class: âenergyâ
state_class: âtotal_increasingâ
here is list https://developers.home-assistant.io/docs/core/entity/sensor/#long-term-statistics
mqtt is reliable, it just needs to be updated every 30 seconds, otherwise it will be lost
by command >- R/yours_victron_id/keepalive
is the Assistant really obligatory?
I red from Victron website that I need to put firmware v2xx or v3xx instead of the current v4xx
