Modbus binding with Sunny Boy SMA inverter

[Kim_Andersen]

@rossko57

The SMA “quirk” may come down to it wanting registers read in multiples of four or something, we have no way to guess. There may well be inconsistency amongst models.

There sure are some problems… I cant compress all of them for some strange reason…(even in small groups)
I just tried making a group of these registers.

	Bridge poller power_a [ start=30773, length=18, refresh=5000, type="input" ] {
	    
	       Thing data power_west       [ readStart="30773", readValueType="int32", readTransform="JS(smalimit.js)" ]
	       Thing data active_power     [ readStart="30775", readValueType="int32", readTransform="JS(smalimit.js)" ]
	       Thing data power_L1         [ readStart="30777", readValueType="int32", readTransform="JS(smalimit.js)" ]
	       Thing data power_L2         [ readStart="30779", readValueType="int32", readTransform="JS(smalimit.js)" ]
	       Thing data power_L3         [ readStart="30781", readValueType="int32", readTransform="JS(smalimit.js)" ]
	       Thing data volt_G1          [ readStart="30783", readValueType="int32" ]
	       Thing data volt_G2          [ readStart="30785", readValueType="int32" ]
	       Thing data volt_G3          [ readStart="30787", readValueType="int32" ]

  	 }

But it seems like I cant get the length right. It should be 18, but then I get an error. If I use 16 or 14, I get an error on register 30773, (something about lenght beeing 12, which makes no sense.).
So there do seem to be some issues with this. But only for some registers it seem. Its pretty weird!

This is what happens when I set the lenght to 18.

@rossko57

I’d still advise using unique Thing UID (names)
It does work where one is a Bridge and one is an ordinary Thing, but it’s a risk to your own sanity as well.

I´m working on it

[rossko57]

@Kim_Andersen

It should be 18, … If I use 16 or 14, I get an error …

Yes, there is some config idiot proofing, example -

Bridge poller xxx [ start=100, length=10, ....
	       Thing data zzz  [ readStart="120",

is going to error because 120 does not lie within the 100-110 polled block.

I would suggest try length 20, you had an earlier example of that working.

Remember when editing poller things in flight with a less than very latest binding version, there can be confusion with cached settings. Restart the binding if in doubt.

@rossko57

Yes, I just restarted OH, and things seems to went online just fine.
This is my main inverter (the Tri Power). It is dark outside right now (22:41 o´clock) so I cant really tell untill tomorrow if its actually working.

(Note!! Restart of binding is a highly bad idea, when running a serial modbus as well… My Nilan setup (serial RTU) went bananas when I restarted the binding only. So I had to restart OH insted. Damn how I hate this serial/USB/Linux shi*** ).

[Kim_Andersen]

@rossko57
What are the different readValueType formats.
In thedoc of the registers for my inverter, I see U32, U64, S32 and STR32, S16.
In the modbus doc I dont see S32, STR32 and S16.
What are these type?

Bit value type must be used with coils and discrete inputs. With registers all value types are applicable. 
Valid values are: 
"int64", "int64_swap", "uint64", "uint64_swap", "float32", "float32_swap", "int32", "int32_swap", "uint32", "uint32_swap", "int16", "uint16", "int8", "uint8", or "bit".

In my original setup (original copied from Nana) I had uint32 readValueType in some data, even though the SMA modbus register says format int32…
Is it a typo/mistake/anything? It doesnt seem to do any harm though.
I have changed it to int32 in my new setup. Still no harm done, (I hope).

[rossko57]

As before, Modbus protocol only knows 16-bit registers. (and the on/off types)

There are established conventions to fit on top of that. For example, make an effectively 32-bit register by sticking two 16-bit registers together end to end. There’s now a choice, do you stick them together as A + B or B + A? There’s no rules about this. There’s no rules about what to name it. This is the origin of what openHAB calls _swap (or not).

Looking at the openHAB names, example int16 and uint16.
It’s pretty common to treat a 16-bit register as representing an integer number, 16 bits can then be interpreted as decimal 0 - 65535. That’s uint16, where the U is for Unsigned. Signed?
There’s a very common computing convention to allow negative numbers in binary registers called “twos complement”. This allows our 16 bits to represent decimal integers -32768 to +32767. That’s int16.
It so happens that the 16-bit patterns for values 0 to 32767 are exactly the same in int16 and uint16 - so often you cannot tell the difference even if you guess wrong.

Remember all that comes over Modbus is 16-bit registers, this is all about interpretation. Which means the slave designers decide what they mean, we have to guess or read the docs. What the slave designer might call the various possibilities, we don’t know. You might now guess what the U and S are about in the SMA docs, though.

There are reasonably well established general computing conventions to represent floating point numbers - like 3.1417 - in 32 or 64-bit registers. In particular an IEE standard is very common, and so openHAB provides dataTypes for that.

STR is a good one. I’m guessing it might be String.
It’s possible to pack encoded characters or suchlike into those universal 16-bit registers. You might do that in two 8-bit characters, again we have the A+B or B+A problem, this time internal to the register. You also have to know what character encoding they use - ascii, unicode, blah?
String over Modbus is fairly unusual and unwieldy, and given the large number of variations openHAB presently has no decode for this. You can make your own with transformations, or exploit the uint8 form and use rules to decode.

All of which means … I can’t tell you what SMA means by it.

[Kim_Andersen]

Hmm… So:
int16 is for negative to positive number (ie -32768 til +32767)
uint16 is for positive number only (ie 0 - 65535)…
Which means, if a register can never return a negative value, it will be an uint16? But if it can return an negative value it will be an int16 ?

I know there are alot of guessing going on here. But I´m also trying to understand, so I at least have a fair chance to guess right

I think you´re right about the STR32 beeing a string. It seems to be use for IP, DNS, MAC adresses ect.

Here are some examples from the modbus registers of my main inverter:

Modbus register address	Short description / Enumerators	         Unit	Format	Type	Access
30513	                Total yield                  	         Wh	    U64	    FIX0	RO
30529	                Total yield                              Wh	    U32	    FIX0	RO
30773	                DC power input [1]           	         W	    S32	    FIX0	RO
31017	                Current speedwire IP address	                STR32	UTF8	RO
41029	                X value 1, conf. of grid integr. char. 1        S32	    FIX3	RW

Seems logic… except:
I still dont get the difference between S32 and U32.
and
Why the heck is there a Total yield in both U64 format and U32 format?

Also notice a funny thing I just have to show:

30539	                Daily yield	                             MWh	U32    FIX0	RO

How many 6000Watt inverters are capable pf producing MWh pr day??
(I know why they have this option… Its just funny to see from its description)

[rossko57]

@Kim_Andersen

Which means, if a register can never return a negative value, it will be an uint16 ? But if it can return an negative value it will be an int16 ?

All you get over Modbus is 16 bits. All registers look alike.

1000000000110101 might mean 32821 as a uint16 type, or it might mean -32715 as an int16 type, or it might mean “€5” as string characters, or it might be part of a 32-bit value and be useless on its own,

Any register can represent a negative value, or string characters, or screen pixels, or blah. It’s entirely up to the slave designers whim.
You have to guess or find out what meaning they placed upon it, so that you can apply the same meaning at your end.

Having discussed Signed and Unsigned numbers, what do you think SMA might mean by S32 and U32?

[Kim_Andersen]

@rossko57

Having discussed Signed and Unsigned numbers, what do you think SMA might mean by S32 and U32?

int16 = Signed
uint16 = Unsigned
S32 = Signed
U32 = Unsigned
STR32 = String (most probably).

Got it

Hi,
I was reading many articles regarding modbus and sma tripower. I’m not able to get it to work. When I use separate modbus poll utility I can read some data.
My setup is very simple and added the openhab.log and events.log snapshot.
I hope someone can read the logfiles and explain what is wrong.

[mstormi (Markus Storm)]

Can’t help with that but the SunSpec binding has become available now, and if I’m not mistaken SMA supports that. So maybe it does what you want.

[Kim_Andersen]

I have yet to figure out what exactly is the difference between modbus and SunSpec, except its same.

I doubt using SunSpec binding will solve his issue.

[HenMus]

Thanks Markus. This doesn’t help I expect because it still requires modbus.

[Kim_Andersen]

I dont see anything wrong in your setup. But I wonder if you´re having a network issue somehow. It seems like its the Bridge going on/off all the time.
It may require you to activate the trace log to see more.

Maybe @rossko57 got an idea of this one.

[rossko57]

Not much more to be seen, yet. If you’ve been editing your Things, I would recommend a binding restart at least.

[HenMus]

Hi Rossko57, Thanks not sure how to do a binding restart but it triggered me to uninstall the binding and reinstall it. Afterwards the value was shown perfectly. Thanks. I’m still learning but making progress. Next job is adding a database in graphical representation.

[yphyph01 (Yann)]

Hi @Kim_Andersen,
May I ask you to share your final config files for the SMA Sunny Boy setup? (Things, Items, Transform & Sitemap) This would be very useful for future openhab users
Thank you

[Kim_Andersen]

Sure. I´ll upload them later (tonight) as I´m at work right now.

[SHO (Steen Holm)]

Hi @Kim_Andersen
I have 2 SMA Sunny Boy (2500HF and 3000HF) with standard communication module Bluetooth, what communication / interface module do you have to get the Modbus data?

[SkizzoSaar (Stefan)]

Not sure whether this will help but I’ll try to give my 50 ct…

Concerning modbus an sunspec I read some questions before: modbus is a protocol. Sunspec uses modbus protocol. The sunspec modbus profile defines specific registers and data types for measurements or parameters. Some of them are read only, some of them can also be written. Take care, not all of them are meant to be changed but only to be set once. Changing them continuously will destroy flash memory. SMA has documented this well.

At least in some SMA devices Modbus TCP is not activated by default. For Sunny Boy Tripower as well as for Sunny Boy Storage you’ll have to enable “Modbus TCP Server” to use it with openHAB.

When you try to read out sunspec modbus values you have to take care of the registers adresses, theres an offset. SMA:

To read or to write Modbus registers in each case use register numbers reduced by the
offset of 1. Example: Modbus register address = Modbus register number in SunSpec
Modbus profile – offset = 40001 - 1 = 40000.

Not all SMA devices serve all values.
