I don’t know much about it. But i use sunnyportal.com to look online. And local I just go to my ipadres.
I have a Sunny Boy 3.0 1AV-40 and I live in Belgium. I use HA on my synology
Thanks for the reply. That probably explains it then. My inverter is about 5 years old, you have one of the newest models with the network interface built in… They obviously have changed the interface.
Sorry i can’t help you with the problem. That was the only problem I’ve got 
Hi. Did you solve this in the meantime? I have the same problem.

I have been unable to connect to my 5000TL-21 with the additional WebConnect module.
Spoke to SMA Australia, and apparently this model will only connect with Sunny Portal or Sunny Explorer - no internal web interface.
I wonder if this is the same issue a few others have encountered. Using Sunny Explorer I could connect via bluetooth and see that the WebConnect module had an IP and was happily sending data to Sunny Portal - but could not access via browser on the LAN.
for old Sma inverters with web connect you can enable modbus over tcp…

Thanks for sharing mamra.
But i’ve tried to connect via the modbus, i can’t reach my device.
Error:
Connection to (192.168.1.175, 502) failed: timed out
code from configuration.yaml:
modbus:
- type: tcp
host: 192.168.1.175
port: 502
I’m sure that the right IP from my SMA STP 6000TL, because i can read it from my local Sunny Explored connected trough speedwire.
Any idea’s?
Found it…
In the Sunny portal i had to turn on tcp server.
Hello MatijnB,
We bought an second hand inverter with an Webconnect unit. I cant connect by http and my modbus isn’t working to. Can you explain me where you turned on the tcp server?
I can’t login to an HTTP web interface,
but if i look in the Sunny Explorer there isn’t an option to turn it on. The only option i am seeing is Webconnect : on/off
I am using the SB 3000TLST-21 408 in combination with an SWDM-10 connected to my router.
I have also a WebConnect with only the “SMA Portal”. I don’t have the right to enable Mobius so I looked on how to extract the data directly from SMA Portal as my feed to there is working fine.
I have this under test right now. This is a python script to be executed under “AppDaemon” integration.
Don’t forget to replace xxxxxx & yyyyyy with your credential.
Probably still some debugging needed (I don’t know yet how long I can keep active my session, I try a check every 5 min and a logon once per hour.

i know it’s been a while since you posted your config. but i implemented it today, and it is working fine for all values, exept for PV Daly Yield
name: PV Daily Yield
unit_of_measurement: kWh
slave: 3
register: 30517
scale: 0.001
precision: 3
count: 4
data_type: uint
the PV total production is totaly correct, but the daily yield should be around 0.361kWh but is showing something completely different. could it be a wrong register? is there a way to find our the correct register?
i’m completely new at modbus. but you code works fine, except for that value
i anyone could help me out… thanks.
What model of inverter do you have? Download from sma site >support >downloads under your inverter range the excel file of modbus… Check there what register is the daily yield
Also check the total production register. It seems low
Andreas, thank you for your reaction. the total production is oké, the solar panels have been installed a few days ago, so that explains the low value…
i have a Sunny Boy 3.0, SB3.0-1AV-41 575.
i found the list you mean, in html format. https://files.sma.de/downloads/MODBUS-HTML_SBxx-1AV-41-V11.zip
my current register in my config file is:
- name: PV Daily Yield
unit_of_measurement: kWh
slave: 3
register: 30517
scale: 0.001
precision: 3
count: 4
data_type: uint
so the register number seems correct.
do i have to change other register values, if i would like to try register 30537.
do i have to do anything with “Number of contiguous SMA registers” = 2 and “Data type SMA” = U32
do i have to change something to “data_type: uint”
Sma registers == count so you have to Change to 2.
thanks but doesn"t seem to work, i’ll have te look into it a bit more.
when i try count 2, i have this:
- name: PV Dagelijkse opbrengs
unit_of_measurement: kWh
slave: 3
register: 30535
count: 2
scale: 0.01
precision: 2
data_type: uint
but i just keep getting -0,001kw
Weird…
your settings seem correct:
u16 ( count 1) or 32 ( count 2) or 64 (count 4) are for unsigned words
FIX0 is decimal number with no decimal space
data type is uint (unsigned integer)
try again register 30517:
- name: PV Daily Yield
unit_of_measurement: kWh
slave: 3
register: 30517
scale: 0.001
precision: 3
count: 4
data_type: uint
if that doesn’t work try sunspec registers at slave:126
