Hi
I think I’ve done everything according to your info but get this when I´m trying to add the integration.

No. The password from the webportal is not the right one. The default password for speedwire is 0000 (=user) or 1111 (=installer).

How have to installed the integration?
Have you really used hacs to install my integration?
They don’t work 
I have a Tripower 10 with a Home Manager 2.0. After adding the system using this custom integration, I would like to create an automation to have zero feed-in during negative day-ahead prices, preferably not zero production at the inverter side as this isn’t beneficial for grid tariffs in my country. I’m able to do this manually in sunnyportal by setting the following to zero, but with more and more negative prices (basically every weekend now), this is becoming a hassle:
After adding the device, I see the following parameters in developer tools, does anyone know the difference between the two, and which one to use?
option 1:
option 2:
How should I interpret the responses, do the values represent the minimum and maximum values I’m allowed to assign? How should I set these values given my 10kW inverter power.
option 1:
typ: min/max
values:
- 0
- 500000
option 2:
typ: min/max
values:
- 0
- 10000
The two values are actually the minimum and the maximum respectively.
see ha-pysmaplus/docs/set_parameter.md at 5ac1b7e386125ee7775ac35c67eb2204a69f6fcd · littleyoda/ha-pysmaplus · GitHub for more information about the two parameters. One of the parameter is for the limit on inverter and the other for a limit at the grid connection point.
In your case setting the limit at the GCP should work.
Thanks for your reply, and for the nice integration.
I have it up and running, and the inverter+HM2.0 setup seems to respond to the setpoints sent from the Home Assistant initally. However after a while, the inverter seems to automatically switch off the power limitation option at the grid connection point.
the setting in yellow is the one that gets updated when using SMA Devices Plus ‘Set Parameter’ on STP10.0-3AV-40 947 Active Power Limitation (GCP) as an action in my automation.
the setting I highlighted in blue automatically switches back to the “Off” state after a while… Is there anyway to get around this? Could I also modify this parameter via this custom integration?
I only used the “SMA Devices with Webconnect” option when setting up, I saw there’s also a “Sunny Home Manager 2 with Grid Guard Code” and “SMA Energy Meter/ Sunny Home Manager 2.0” option, but I didn’t use those, not sure if I should do that and if that’s relevant…
As written, I can only help you to a limited extent. I have only built in the respective parameters for different users.
You could look directly on the inverter website to see if there are any parameters regarding limitation on the GCP.
Maybe this thread will help you.
What I can tell you, however, is that neither the Energymeter, SHM (with GGC) nor Speedwire options will help you. They have no control options.
Thanks for the reply @swante, off course I don’t expect you to fix and tailor this to everyone’s specific set-up, I posted it here to check if others bumped into the same problem and if they found a fix. I’ll tinker with it and post an update here for future users that have the samme problem.
I found a fix to the gcp inverter limit command being automatically reset by SMA. I posted it in the thread @swante suggested where the shell commands are being used: Feature to set power limit of SMA STP inverter from Home Assistant - #22 by GH-R2D3
Hello,
I installed this integration, all is working well but I have a temperature sensor that I don’t understand.
My inverter is a SUNNY BOY SMART ENERGY 6.0
The name of the entity is “SBSE6.0-50 Temp A” and is shows a temperature of almost 80°C !
I do not think that it’s a real temperature because just In the immediate proximity of the inverter it is not hot and the ambient temperature is around 22 degrees.
Also, I do not understand why there is a “A” => “Temps A”. I have 3 MPPT on this inverter and I have the information of the 3 MPPT such as “PV Voltage A” “PV Voltage B” “PV Voltage C”.
Do you have any idea ?
Thanks you.
80°c is quite realistic. Go to the website of the inverter, log in and you will most likely see the same values. The value is probably the internal temperature directly at the voltage converter
If several temperatures are returned, they are labeled A,B,C,… There is no direct correlation to a specific input or output.
I can’t see any temperature on the inverter website this is why I am wondering which temperature is it.
interesting. The integration is using the same data source that is also used for the website on the inverter. Perhaps SMA has decided not to display the values. However, the values look absolutely realistic to me, especially with the curve over the day.
I have a Sunny Tripower X 15, which is why the temperatures are not really comparable. But I have installed additional coolers to lower the temperature. Nevertheless, I still get 70°C. Wihtout the coolers I reached 90°C.

Thanks you it helps !
As the operating Temperature is -25 ~ +60 ℃ I was surprized to see almost 80°C even if the “operating temperature” is the “ambiant temperature”
Hi,
Enjoying your integration much. Is there a way to unlock all the disabled entities below? All the ones of interests were of course locked… I wanted to monitor all the strings for research…
Sorry, didnt know it was a HA config… One just enable it in the SMA integration.
