The "old" Sunnyboy 2.5 will not respond to DNS/SD:

My "old SB2.5 with updated firmware is not discovered. I can find him with his SMAxxxxxxx.local Address but he will not be found.

It'd be great to add "manual" configuration for the inverter.

  1. What does your network topology look like? Is the computer running Homebridge on the same subnet?
  2. Can you ping SMAxxxxxxx.local from the computer that is running Homebridge?
  3. What do you see if you run dns-sd -B on a macOS computer (preferably the one running Homebridge), or use the "Discovery" app (https://apps.apple.com/be/app/discovery-dns-sd-browser/id305441017?l=nl) on iOS?
  4. Can you enable "Debug mode" in Homebridge? Then you should see something like Allow setting inverter IP via config because link-local addresses like 169.254.12.3 do not work on Linux #3 (comment).

FYI the current approach was chosen based on real-world feedback — see #3.

since the SunnyBoy 2.5 and other elder models do not have OS on board they do not answer to service discovery nor have a web server available.

Woah! That must be very old 😄

There is an original SMA documentation on how to discover SMA inverters in a network which should work for ALL inverter. I attach the document to this mail, it includes information on how to proceed as well as some sample code.

I can't see that document — GitHub's "reply to e-mail to post on the issue" service is 💩 🙈

WRT Speedwire: see #16 — even the maintainer of https://github.com/SBFspot/SBFspot says there's no docs for this 😅

So … if you have such a document, please do upload it here, on the GitHub issue! 🙏 🤩

The SMA device discovered is a SMA EV-Charger ;-)

Aha! 😅 I was going to ask about that. Thanks!

WRT SpeedWire being closed source, there's also #4. See #4 (comment). A firmware update of the inverters caused new messages to appear, which are completely undocumented.

This was also reported against other projects, such as SBFspot/SBFspot#626.

I attached the SMA documentation (original from SMA Developer Website):

SpeedwireDD-TI-en-10.pdf

I hope this can help - discovery will work for ALL SMA devices (starting from around 2011).

Be aware the Python example in the document has an error:
spwMCastAdr = 239.12.255.255
should be
spwMCastAdr = 239.12.255.254

OK / NOK depending on what you want to address. Multicast adresses are derived from SMA Data2+ MCAST Addressing. So 239.12.255.255 is addressing "devices" in the local bus - it will find inverters. With *.254 ALL devices including loggers are addressed.

Thanks for that, both of you!

@sbf- , are you using Speedwire discovery as described in that document in https://github.com/SBFspot/SBFspot?

Yes, when IP=0.0.0.0 is configured

Any additional information on that issue?
I think this is linked to issue: "Inverter not discovered":
#20
