Yes, this is the manual which came with the unit - it’s definitely the M version.

Oh dear, well on the plus side things have got further along so we’ve conquered one hurdle, but it seems there are other issues. I’m not at a pc right now and will have a look later.
Modbus is renowned for getting the 2 com wires confused and as it is safe to swap them, before delving any deeper try swapping them over to see if it gets further or not. May need another restart.
Thank you Paul.
I had read that devices often got their 'A’s and 'B’s mixed up, but have not tried swapping them.
Will try in a bit and report back.
Uncomment these 2 lines to see what you have got back
It will still throw and exception.
[edit]
this may help. sdm-modbus · PyPI
[edit2]
There is an example.py there you could try (remove the emonhub interfacer config first)
I hope the swap makes a difference because a 2nd look at the code snippet I posted previously shows there is very little in between the mentioned "If . . . " line (L70) and the newly failing log line (L76) in fact just one line to “read_all” the registers (L71), if that is failing I suspect either a HW fault (poor conn or swapped conns etc) or a sdm_modbus library issue since the implementation is very minimal.
Ideally there should be some try/except clauses in there with better error reporting, and handling to avoid crashing out as you are currently seeing.
No, it seems this interfacer skips using the [nodes] section altogether and opts for hardcoded names in Line 78 of the same snippet.
I have to say I prefer the more generic library names to the hardcoded alternatives, since all the inputs will be posted under a node name of “sdm_120” (or similar) the “sdm_” prefixes make the input names somewhat more vague eg “sdm_120:sdm_P” isn’t as clear as “sdm_120:power” but I assume this is done this way to accommodate MQTT perhaps? This is specifically why node definitions (and default settings) are IMO important.
I’m guessing this is a WiP and just an early release of unfinished code.
My previous approach with the symlink was to avoid editing the source as I was unclear how comfy Sean was with it and it will block (hopefully imminent) updates via git. If Sean is happy to edit the source then adding a couple of simple try/excepts would avoid the crashes and the whole result of read_all could be logged rather than that commented out first level loop which will crash if r = None.
I will get on this now and make the changes to the code. Should have an updated version to test shortly.
@TrystanLea I have just submitted a PR
Please test it first if you use it as I was unable to test.

Thanks again @pb66, tested here, with a minor modification to the connection
self._sdm = sdm_modbus.SDM120(device=device, baud=int(baud))
it worked fine.
I will have a look at improving the options to name the parameters.

I’ve added a prefix option which makes the sdm_ part optional.
[[SDM120]]
Type = EmonHubSDM120Interfacer
[[[init_settings]]]
device = /dev/ttyUSB0
baud = 2400
[[[runtimesettings]]]
pubchannels = ToEmonCMS,
read_interval = 10
nodename = SDM120
# prefix = sdm_
In the code there is an array that defines the SDM120 key’s to read, short names and number of decimal points to round the value too:
read_keys = {
'voltage':('V',2),
'power_active':('P',2),
'power_factor':('PF',4),
'frequency':('FR',4),
'import_energy_active':('E',3),
'current':('I',3)
}
The parameters are then read if present in the data returned from the SDM120:
for i in read_keys:
if i in r:
c.names.append(self._settings['prefix']+read_keys[i][0])
c.realdata.append(round(r[i],read_keys[i][1]))
The prefix is blank by default so inputs will appear under nodename SDM120, input names: V,P,PF etc.
My own use case is posting the SDM120 data alongside MBUS data under a single nodename called heatpumpmonitor and so the prefix is useful so that I can then set the inputs to be: heatpumpmonitor:sdm_V etc…
@srt these recent updates are still in the emonhub master branch for now. With a bit more testing I will merge them into stable and do a release. For now would you mind switching to this branch to test the new changes?
The steps are (via SSH):
cd /opt/openenergymonitor/emonhub
git checkout master
git pullAs @srt has modified some of the files, he will need to get rid of the changes by checking out that file first else Git will complain.

One thing, I think it is bad form to drop experimental stuff into master - it should really go into a dev branch first IMHO, merged to master for final testing and then released as stable.
You have told me many times @borpin 
I think there are too many steps, perhaps we should just have stable and development for the main branches… I do leave features in a specific feature branch when they are really experimental but try and bring them into master at least when they dont break anything else, even if the feature itself in this case the SDM120 reader is a very early version of the feature. I just find things go stale very quickly if left in feature branches for wider testing. I know I’m not going to get agreement on this.
Edit: I think @srt is the first person to use this in 2 months? or at least post an issue…
Why have you opted for hardcoded names albeit with a prefix rather than using the existing practice of using [nodes] definitions? “Voltage” is obviously more user friendly than “sdm_v” or just “v” especially as there is no way to change the names in emoncms if you want data via mqtt?
There is no reason you couldn’t have a default array of names eg sdm_v, sdm_p, etc and let users define their own array. Likewise for precision levels.
Although the oem emonhub follows the emonhub-wide [nodes] definitions I am veering towards interfacer level node definitions so rather than a [nodes] definition you could easily have names = voltage,power_active etc and precision = 2,2,4 etc in the interfacer [[runtimesettings]].
However, I personally would prefer to see users able to define any number of the available values in any order so they can create thier own node formats eg
values = power_active, voltage
names = Power, MainsVoltage
precision = 2, 1
would give a node of 2 values, “Power” first to 0.01 units (I assume Watts?) and MainsVoltage to 0.1 volts. This might not have much effect on “status” type MQTT but when frames of data are posted via http (and hopefully MQTT too) you can select the order the inputs are read and processed, very important when using more than one input in a calculation during processing.
@pb66 true that could work fine, so the values setting would define the SDM120 parameter order to map to names and precision… is values the best name for this?
Whilst I don’t disaggree with what you say, the naming of the branches is what causes the confusion, ordinarily development is done in another branch eg “dev” and merged to “master” after final testing, only after a release has seen the test of time could it be called “stable” so really oem stable = master and oem master = dev since master is usually where the releases come from not from “stable” as is the case with oem.

Ha Ha!
Yes naming is crucial, eg above eg rfm12pi (with rfm69 module) or emoncms id/name name/desc etc, not our strongest point, ay?
I’m not fixed on “values” it possibly isn’t right but it needs to be generic so that all interfacers can reuse without issue (for example using “interval” rather than “read_interval”), I was just floating the concept as I really don’t like hardcoded elements so IF changes were being made I hoped this would approach could be considered.
I first used this approach for the wunderground interfacer even before emonhub experimental branch.
[edit - just looked to see what I used back then]
Currently available datafields are “temp_c”, “feelslike_c”, “dewpoint_c”, “heat_index_c”, “windchill_c”, “wind_mph”, “wind_gust_mph”, “visibility_mi”, “precip_1hr_metric”, “precip_today_metric”, “UV”, “wind_degrees”, “pressure_mb”, “pressure_in”, “pressure_trend”, “relative_humidity”, “temp_f”, “feelslike_f”, “dewpoint_f”, “heat_index_f”, “windchill_f”, “wind_kph”, “wind_gust_kph”, “visibility_km”, “precip_1hr_in”, “precip_today_in”
Which any number can be strung together as csv, in any order to create a frame be passed to emoncms eg
datafields = relative_humidity, feelslike_c, pressure_mb
I think datafields works well, it’s generic and clear.
