Avoiding wireless connections - EmonTX serial RPiZero solution

[Robert.Wall]

No, only the ones sharing the same designation.

The UART connector is specifically for the programmer, the screw terminals are specifically for I/O, such as the temperature sensor and pulse input.

If you want the nitty-gritty details, take a look at the circuit diagram (ideally, you need to download and install Eagle CAD (free for personal use with the size of PCB we use) then you can see the same track highlighted on the pcb and on the circuit diagram.

[borpin (Brian Orpin)]

I think they are but I was thinking of this

[borpin (Brian Orpin)]

@haffle, @Robert.Wall, I think I have worked out why the writing of the firmware from the RPi directly didn’t work. The utility is using Python not Python3.

EMonTX Bad data after upgrade

TL;DR The utility avrdude-rpi still uses python which may be the issue @bwduncan @TrystanLea. @Martin_Harizanov - I note OEM fork is from you. Went back to the original repo and is still python as well. In detail… Interesting. Start ATmega328 serial upload using avrdude with latest.hex chmod: cannot access '/var/log/emoncms/firmware.log': No such file or directory Attempt: 1 avrdude -c arduino -p ATMEGA328P -P /dev/ttyAMA0 -b 115200 -U flash:w:/opt/openenergymonitor/emonpi/firmware/compile…

[haffle (Julian Berry)]

Interesting. And I am so pleased to learn that it was probably not all down to my ineptitude causing that grief the other week

[haffle (Julian Berry)]

Hmm, first drop out, despite the Pi Zero still being accessible via the IP address. Looking back at a Feed graph it must have gone wrong on Sunday.

Can one learn anything from this emonHub log? What might be the solution?

TIA

[borpin (Brian Orpin)]

This is a problem with the Serial data from the emonTX.

@haffle

MainThread SerialTx thread is dead.

It could be dying and trying to restart repeatedly.

Try resetting the EmonTX as a starting point I suggest.

@bwduncan, could this exception be handled more gracefully (error in log and discard frame)?

[haffle (Julian Berry)]

Thanks @borpin ; pressing the Reset button didn’t kick the Inputs in to life, so I powered the Pi Zero down through the EmonCMS / Admin page, waited a bit then powered both bits down and back on again. But that too has not cleared it.

There is always a chance that it is a physical issue - jumper lead coming dislodged etc, but that seems unlikely as the unit is screwed on to a purlin high up in a rodent / bird / cat free barn in close proximity to an Apple Airport Express.

[borpin (Brian Orpin)]

You can see from the emonhub log, the issue is the serial connection between the EmonTX and the Pi.

@haffle

pressing the Reset button didn’t kick the Inputs in to life

You need to look at the emonhub log and see what it is telling you.

[Bill.Thomson]

@haffle

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc2 in position 19: invalid continuation byte

Not sure how relevant this is, but here’s some info on that particular error:

"for line in..." results in UnicodeDecodeError: 'utf-8' codec can't decode byte

[borpin (Brian Orpin)]

Except that there is no good reason, I suggest, why the data isn’t utf-8. @Robert.Wall?

[Robert.Wall]

What data are you referring to, exactly?

As far as I can tell, the emonTx sends to the serial port nothing outside the range [0x0a, 0x0d, 0x20-0x7f] and I think those characters lie wholly within the utf-8 character set.

If the baud rate has become wrong for an unknown reason, then I cannot predict how characters within the utf-8 set will be interpreted, but it’s feasible that the result of a wrongly interpreted character could well fall outside the utf-8 character set.

[Bill.Thomson]

@borpin

Except that there is no good reason,

Although that may be, something is afoot. Otherwise, there’d be no error, or a different error.

[haffle (Julian Berry)]

Thanks All. I’m afraid the stacksverflow.com thread is above my knowledge so haven’t changed any code. If this PiZero / emonTx is producing a duff character I wonder why the other three aren’t? They were all set up following the same steps.

I am able to interact with the emonHub (& emonCMS etc) fine, so comms at a certain level are working, but the emonHub log suggests that the process(es) just get stuck after a short period following a soft Re-Start. No data has arrived on my emonPi’s emonCMS.

Exactly my point - if the EmonTX only sends data within utf-8, then there should be no reason to change the char set.

@Bill.Thomson

Although that may be, something is afoot.

There is definitely something afoot, I just don’t think the char set is set wrong (see above).

@haffle

Meanwhile, this is the current emonHub output:

Hopefully that isn’t all you are getting

I think you are running the newer Image based on RaspberryOS, I wonder if something has changed in the serial configuration. We currently do;

openenergymonitor/emonhub/blob/a9e47bf684f62632a118196e5aec806efba64be4/install.sh#L33-L33

as part of the install.

However, if 3 are OK and one not, it implies a local problem.

First point is to check header soldering on the Pi and the cable crimps.

I’ll say this again the connection to the Pi is via Wi-Fi and nothing to do with the connection between the Pi and the EmonTX.

What you could look at is the system log to see if there are any other issues.

sudo journalctl -f

[Robert.Wall]

@borpin

First point is to check header soldering on the Pi and the cable crimps.

And check at the emonTx end as well - get it out of its case and carefully look at everything.

Is there a local source of interference that could be getting onto that serial connection?

[haffle (Julian Berry)]

@borpin

Hopefully that isn’t all you are getting

I may have missed something, but it is; I have just logged back in and the EmonHub log of the PiZero in question is still the same as earlier today (see above). Clicking Restart brings up the same return.

OK, hands up, I hadn’t realised this (or at least hadn’t internalised it!), as I had assumed (yes, I know, I know) that the two devices communicated via the Rx & Tx pins (and to a lesser extent the RST pin). But I know now

I will unplug the emonTx & PiZero & open the case and re-check the wires etc. The only thing that is different to the other PiZero’s that might be causing interference is the (un-insulated) corrugated tin roof that it is near; I will bring it down from the purlin and see if that helps.

emonPiLCD.service

That really doesn’t need to be running

sudo systemctl stop emonPiLCD.service
sudo systemctl disable emonPiLCD.service
sudo systemctl mask emonPiLCD.service

Try pressing the EmonTX reset, while watching this syslog.

@haffle

The only thing that is different to the other PiZero’s that might be causing interference is the (un-insulated) corrugated tin roof

No that isn’t going to be the problem.

@haffle

I may have missed something, but it is; I have just logged back in and the EmonHub log of the PiZero in question is still the same as earlier today

That implies there is nothing coming from the EmonTX.

How is this pairing powered? PiZero powering the EmonTX or the other way round?

Try a different power supply.

You could try stopping emonhub and connecting to the TX with miniterm.

The LCD issue is unrelated (I expect).

[haffle (Julian Berry)]

Sorry for the delayed response, but I’ve almost got to the point that I don’t know where to start. I have just shut down the PiZ through the emonCMS / Admin page, but before I did so I downloaded the emonHub log - see below. What is strange is that since ~ 00:00 on the 9th Nov it has “almost” been running correctly, albeit nothing arrived in that period on my emonPi. Note: although one CT input has been attached, no current is flowing through it as I am still waiting for my barn inverter to be fixed and that is the only thing this emonTx is monitoring.

Anyhow, to confirm that the PiZ is powered by the emonTx; the emonTx is powered by an IDEAL -POWER AC/DC, output 5V 2A, and also an IDEAL POWER 9VAS 6VA brick. I am 99% sure that both came from the OEM shop.

@haffle

sudo: unable to resolve host emonTxPiZero1

@djh

How did you set the hostname?
What is in /etc/hostname and /etc/hosts?

Delving in to places I have not been to before, the contents of /etc/hostname is just emonTx_PiZero_1 and /etc/hosts is …

127.0.0.1	localhost
::1		localhost ip6-localhost ip6-loopback
ff02::1		ip6-allnodes
ff02::2		ip6-allrouters

127.0.1.1	emonTx_PiZero_1

I can’t remember exactly when or where I gave the name emonTx_PiZero_1 but I do recall the other three are similarly named but with _2, _3 & _4.

I changed the “name” of the PiZ within my Unifi USG’s control panel to “emonTx PiZero (top barn)” and given it a static IP; I have done this with all of my devices, including the other 3 emonTx/PiZ combo’s. Looking again within the USG control panel I see that the Hostname of the other three is just emonpi; might this discrepancy be an issue / the cause? But if so, why are the other three running fine, and even this one was running OK for several / many days.
