Good to hear that you got the sensors in HA. My yieldtoday sensor does not show that kind of behaviour. Perhaps a temp. hickup at Solax?
Can confirm that this option works!
Thanks for doing the hard work on this one.

Hello,
IĀ“m totaly new here and IĀ“m thankful for all the clear information and coding written here.
I would like to use Home Assistant to make the best use of my SolaX solar panel system.
But I have 2 inverters, the master and the slaver. They both have their own WIFI and the data of both is merged in the cloud.
Does anyone know how this can also be done in Home Assistant?
Doublet has already written a cool and perfect coding, but can it also be used for 2 inverters that are master and slaver?
Thanks in advanced for the help.
If the data is in the cloud then the api trick must get you the data somehow.
Can you share your response to : https://www.solaxcloud.com:9443/proxy/api/getRealtimeInfo.do?tokenId=202102060300yyyyyyy&sn=SWXXXXXXX
This is the respons of the slaver inverter:
{"exception":"Query success!","result":{"inverterSN":"XXXXXXXXXXXXXX","sn":"SWXXXXXXXX","acpower":106.0,"yieldtoday":1.3,"yieldtotal":712.6,"feedinpower":0.0,"feedinenergy":0.0,"consumeenergy":0.0,"feedinpowerM2":0.0,"soc":79.0,"peps1":0.0,"peps2":0.0,"peps3":0.0,"inverterType":"5","inverterStatus":"102","uploadTime":"2021-05-05 08:49:10","batPower":214.0,"powerdc1":0.0,"powerdc2":383.0},"success":true}
and this is the respons of the master inverter:
{"exception":"Query success!","result":{"inverterSN":"XXXXXXXXXXXXXX","sn":"SWXXXXXXXX","acpower":5820.0,"yieldtoday":5.9,"yieldtotal":1302.5,"feedinpower":199.0,"feedinenergy":597.77,"consumeenergy":1014.05,"feedinpowerM2":0.0,"soc":98.0,"peps1":0.0,"peps2":0.0,"peps3":0.0,"inverterType":"5","inverterStatus":"102","uploadTime":"2021-05-05 13:06:45","batPower":-758.0,"powerdc1":0.0,"powerdc2":5221.0},"success":true}
Good, this would suggest that you can create 2 sets of sensors following my guide: one for the master, one for the slave. With HA you can then create a 3rd set of sensors showing the addition of the two converters with the total production.
Ah, oke. Thanks for the info. This afternoon we will try it. Itās all new for us, so we will see.
Could you maybe write me where the sensors are created in HA, in config.yaml or somewhere else?
Sorry for asking, but its really all new for me, but I would like to learn more about it.
Thanks to your help we managed it to set up the sensors.
We see now all the details from the Master inverter and separately also from the Slaver inverter.
But at the end we tried to combine these numbers so we could get a total of everything, and something we did wrong, because the Ā“total energy usedĀ“ does not work.
So affter we have put the code for the Ā“total energy usedĀ“ below the sensors Master and Slave, we get in the configuration test a fault, but we do not see yet what we did wrong.
This is the code that we used for the Ā“total energy usedĀ“ and something is not right:
############
Gesamtverbrauch aktuell
- platform: template
total_energy_used:
value_template: ā{{ ((state.sensor.master_solax_now | float) +
(state.sensor.slave_solax_now | float)}}ā
friendly_name: āGesamtverbrauch aktuellā
unit_of_measurement: āKWā
.
This is the message that we get in the configuration test:
Invalid config for [sensor.template]: [total_energy_used] is an invalid option for [sensor.template]. Check: sensor.template->total_energy_used. (See ?, line ?).
.
Do you have a idea what we do wrong?
Please use the correct way to post code: put your code between 3 kommaās as per the forum rules:
type or paste code here
So I assume you have two sensors for current PV, two sensors for todayās PV and two for Total. Now we have to add them into 3 new sensors like:
- platform: template
sensors:
pv_now:
friendly_name: "PV Now"
unit_of_measurement: W
value_template: "{{ states('sensor.solax_now')|int + states('sensor.solax_now2')| int }}"
icon_template: mdi:power-socket-de
device_class: power
- platform: template
sensors:
pv_today:
friendly_name: "PV Today"
unit_of_measurement: "kWh"
value_template: "{{ (states('sensor.solax_today')|int + states('sensor.solax_today2')|int) }}"
icon_template: mdi:solar-panel
- platform: template
sensors:
pv_total:
friendly_name: "PV Total"
unit_of_measurement: kWh
value_template: "{{ states('sensor.solax_total')|int + states('sensor.solax_total2')|int }}"
icon_template: mdi:chart-line

YES this works.

I added :
scan_interval: 60
to one of the api calls to see if that will scan at 1 minute intervals instead of the default 5 minutes
I will tell you if it worksā¦
Thanks for this @Doublet !
The default scan interval for the rest sensor is 30 seconds. The update frequency is 5 minutes on Solax side, so the scan interval isnāt going to change things.
I have two Solax inverters (X1 and X3) and I saw in the API documentation there is a request limit of 10000/day. So I changed the sensor a bit, with the purpose of making one rest call and extracting the data I need for the sensors.

@Bobbika Thanks for this extensive example.
I have the same setup of inverters so I could use it with very small alterations.
With the new energy management this became even more important to me.
Sadly it seems that there is no support for template sensors according to this post by @frenck.
I will try to contact Solax again to see if i can change their mind about the local API.
With my setup (X1 and X3 both with pocket lan adapter) the workaround connecting to the SSID locally does not work, obviously.

I have send an extensive request to Solax Benelux to request to open up the local API again for Solax inverters. After my question they build the web api, but that is not really what we need.
My contact is on holiday until august 15th. If there is a response Iāll post results here.

Got it working!! You can add the below code to your config for a sensor that you can use in the energy dashboard:
template:
- sensor:
- name: test_energy
state: "{{ states('sensor.solax_total') }}"
unit_of_measurement: 'kWh'
state_class: measurement
device_class: energy
attributes:
last_reset: '1970-01-01T00:00:00+00:00'
