here the complete modbus and template
Is it working again for you? I still got some problems.
regards,
Chris
Which problems ?
Please define exactly. At everything works again.
Hi Bimbo009!
Looks great! 
Would it be possible that you share the modbus.yaml and template.yaml as code?
I’m about to integrate my SMA inverter and you have some good metrics.
That would save me a lot of manual retyping.
Thx and regards

I was actually responding to @Crash123Crash123, because he has the same unit as I have (SMA Sunnyboy 3600TL-21 , but I tried it with your config now, tomorrow I will check the result.
@Crash123Crash123, Is yours fully working again? (and if so, can you post the config files )
thanks !

Yes, everything works as usual.
The config is already online, see above, except for the beginning with the IP and whatever else is included, but all sensors and template sensors that I use. I wrote the normal sensors so that I can use the conversion that has been available in ha since the last update so that I no longer need them with the Riemann helper and the correct symbols are also displayed immediately.

Then congratulations, it’s not that difficult if you follow the instructions.
However, if you use the right sensor right away, you don’t need to do so many conversions.

Got yours and Crash123 config working, but went for the SunSpec intergration, because is was less work. (the modbus solutions still have errors in the log). thanks for sharing the configs
You can also try SBFSpot, works with Lan too.
I have been tweaking a lot to get this right for my SB4000. Just figured out there is also a min_value: 0 option to get rid of the negative numbers without needing the template.

Hello,
I used the config @Bimbo009 provided, thank you.
I guess everything is working fine.
Now I wondered if I can get the current power consumption or power send to the grid values from the inverter as well.
I tried register 30865 and 30867 but I only recieve super high and wrong values.
I am using a Sunny Tripower 20000TL-30 and a Sunny Homemanager 2.0
The Sunny Home Manager 2.0 unfortunately doesn’t support modbus properly.
You can still get values (grid export, grid import) from it by decoding its multicast messages in Node-RED. More on this can be found here: Home Manager 2: "Direct Meter communication" (Version 2.4.14.R) - SMA - Anlagenüberwachung - Photovoltaikforum
My old SMA from 2013 did never work with modbus or any other integration then scrape, alas that did stop with the new multi scrape too, i would love to see it running again but I lack the skills, could anyone please?
My code used to be:
Webscrapping for SMA Inverter values

platform: scrape

value_template: '{% if is_state("sensor.pv_einheit", "Wh") %}{{ value | float / 1000 }}{% else %}{{ value | float }}{% endif %}'
unit_of_measurement: 'kW/h'
With our dynamic energy contract and negative energy prices in recent sunny weekends I figured out how to shut down my sunnyboy. Similar automation with writing 4000 to the same register to turn it back on.

Hi Roumen
Did you need to setup the modbus in your configuration.yaml to set the registers as an installer profile? In the modbus list this is write level installer.
If so, how did you do this?
thanks
Hi Mathieu,
I installed the panels and inverter myself so I do have installer code but I don’t think I did some special setup for Modbus (apart from enable it) my modus.yaml is a few posts above but nothing special there:

etc.

Regards, Roger.
Can someone help me with the correct modbus commands to STOP and start the production of an SMA inverter? I’m doing this through the web interface now by setting the parameters to “stop” or when desired to start producing energy again set it back to “MPP”. I can’t find anyone doing this so there are no examples and I don’t really seem to understand the basics of Modbus.
I’ve tried this (but failed) in Home Assistant:
