answer to myself, it appears that the chep multimeter types with Current clamp, is only capable of measure AC current, I need also to measure DC current (Then I can measure if my my diesel glowplugs are working, without removing anything), so I bought this fairly cheap add on.
It provides 1mV/A

How to measure with current clamp your glowplugs: (Not my video, but it gave me some knowledge):

AC/DC Current Clamp Meter Adapter Clamp-On Adapter Meter Current Waveforms Tester with Probe For General Multimeter Oscilloscope

And now we have opened the discussion, does any of you know of a current clamp as add-on to use with a regular multimeter? or must I purchase a dedicated multimeter with current clamp?

Try FIRST to level your bed - PLA can't stick to air if you have too much distance between nozzlehead and bed.

@alowhum
NO it can't be used as 3D printer, it's not accurate enough
QA from their homepage:
Would it be possible to place circuit components on circuit boards using this arm or does it not have enough precision?

Yes, the repeatability is 0.2mm, This is enough for PCB soldering.

My 3D printer, zonestar 802 have this accuracy:
XY-Axis Positioning Accuracy: 0.012mm

@crumpy10
Looks like your skirt are fine (The round first prints) but inside your print you get to little PLA through your nozzle
is temperature correct?
is is a good source from PLA? or is it that came along the 3D printer, then swap and use new PLA
If you have Bowden extruder, is it extruding correctly? maybe the gear slips
And then maybe is your bed 100% calibrated?

I don't think your nozzle is clogged as the skirt looks ok

@bjacobse
did you setup Node-RED?
Maybe this can help you: https://diyprojects.io/mqtt-mosquitto-communicating-connected-objects-iot/#.XTBAKiZJFCU

I don't use Webthings, but MQTT shall work similar, on my RPI I have Domoticz and Mosquitto broker running, check in a prompt:
Is the broker running? ps -ef |grep mosq
you can also check the logfile: sudo tail /var/log/mosquitto/mosquitto.log

Then if above is ok, then your test message shall appear in the logfile, then Mosquitto is working. Then next check Mosquitto WebThings connection. I would assume a logfile must be present in WebThings that shows if a sensor is providing something

@berkseo
Good looking device that you have created originally

@nca78
I think you must have misunderstood the concept. I did not use a ethernet splitter and extra cable mess...
I use my router as IP supplier, 1 ethernet cable to my RPI, so I have cable to my domoticz, the RPI gets IP via cable, and if the I'm not able to ping gateway (router) then there is no power as the gateway is down.
the ONLY extra thing I have purchased is a the powerbank

@mfalkvidd
The powerbank I am using is a Linocell 7800mA. YES I AM AWARE that it's stated on the powerbank that it's not allowed to both charge powerbank an use it as powerbank - But that is exactly what I do
