Perhaps a MS Windows thing. Iāll try that here and post results.
Notice your screen shot stating that the image is 2.21GB (wrong)
Notice your screen shot \.\PhysicalDrive2:UNKNOWN: unknown error, write .
What brand SD card are you using?
Maybe etcher for MS windows does not like 32GB image?
I tried version 1.5.19 and it said image was 866.89 - wrong
As expected after flashing for a minute or so it said 99% complete although it did keep on writing! And eventually completed.
Thanks again for testing! It doesnāt matter though, itās all up and running now.
I am using a SanDisk 32GB card. I used Win32DiskImager for my own backup and wrote back the image after formatting to verify it worked too.
Etcher Iāve never used before.
I have the image from dgerman running on a Rpi zero w with one tag.
Just checking/testing to see if the battery/solar system I have can support the load.
Next thing is to see if the data from six tags can be displayed and still readable.
Does anyone have a multiple tag system running and how did you get the data from all the tags displayed in such a way that its still clear?
Heres my rudimentary test system display with a single tag.
You could check the live demo at lab.ruuvi.com for an example on how to organize data from multiple tags.
Thanks Otso, yep I see that now and it may well be what I want.
I have the image safely loaded onto an sd card and get the Rpi GUI after booting up and apparently both BLE and Wifi connections are up, but what then?
Do I need to start influx, grafana and ruvvicollector separately, and if so, how?
They are started by systemctl, refer to the directory:
/lib/systemd/system
influxdb.service, chronograf.service, grafana.service and ruuvicollector.service
See also related links in /etc/systemd/system/multi-user.target.wants
influxd.service, grafana.service
and
ruuvicollector.service.requires
Regarding "see if the data from six tags " does something like
SELECT ātemperatureā FROM āruuviā.āautogenā.āruuvi_measurementsā WHERE time > :dashboardTime: AND (āmacā=āD3517872EC0Fā OR āmacā=āF7FA744A1E1Aā OR āmacā=āE9383FDD20BCā) GROUP BY āMacā
Do what you want?
See http://dalogger.dyndns.org:3430 and check out dashboard 3sensors
Is the image still available at https://mybeacons.info/raspiruuvixxxx.gz?
Thanks dgerman
Hi @dgerman,
Thanks for your active involvement RE Ruuvi gateways and collecting its data 
Iām running through some threads here and saw that you might have an image for the Pi Zero W. Iām aiming to run RuuviCollector on the Pi and then publish payload via https to my own cloud setup and NOT InfluxDB and Grafana setup.
Appreciate the help!
Rgds,
Wzz
The SD image at MyBeacons/RaspRuuvixxxx.gz is for Pi Zero W.
Most importantly because of grafana, SO you might not care.
Pi Zero has a different processor: BCM2835 ARM11 using an ARMv6 <- Important
Pi 3 Broadcom BCM2837 CPU: 4Ć ARM Cortex-A53, 1.2GHz
Pi 3 Model B+ 1.4GHz 64-bit quad-core Broadcom Arm Cortex A53
I will try it on ā¦ later today
You donāt necessarily need to alter RuuviCollector, if you are able to parse InfluxDB line protocol on the receiving side, as the connection between RuuviCollector and InfluxDB (in the standard setup) is standard HTTP POST. In this case all you need to do is to change the influxUrl configuration property.
For example, if I changed the influxUrl to http://example.com:1337 then RuuviCollector would do a HTTP POST to:
http://example.com:1337/write?db=ruuvi&rp=autogen&precision=n&consistency=one
or with influxUrl of https://example.com/some/path/ it would post to:
https://example.com/some/path/write?db=ruuvi&rp=autogen&precision=n&consistency=one
(parameters depending on exact configurations) with following kind of data:
ruuvi_measurements,dataFormat=5,mac=D7D09A60357B absoluteHumidity=4.0374809476748155,accelerationAngleFromX=73.86213543428374,accelerationAngleFromY=16.145033821861915,accelerationAngleFromZ=89.53160256963027,accelerationTotal=0.9785949110842544,accelerationX=0.272,accelerationY=0.94,accelerationZ=0.008,airDensity=1.2148683985819957,batteryVoltage=2.983,dewPoint=-1.415840196649157,equilibriumVaporPressure=2764.5917289802787,humidity=19.9375,measurementSequenceNumber=4055i,movementCounter=117i,pressure=103319.0,rssi=-63i,temperature=22.74,txPower=4i
(note that with batch mode there can be multiple lines like the above (from different tags) in the post data if the measurements are received within the configured influxBatchMaxTime (default 0.1 seconds) of each other)
If you need more fine-grained adjustments, you need to create your own implementation of a DBConnection, you can take a look at the InfluxDBConnection.java and DummyDBConnection.java for examples. You also need to add it to the config.
So you aim to use the limited processing power of the Rpi to handle Ruuvicollector and do the hard work at the receiving end?
Sounds sensible.
Hey there @dgerman,
Really thanks. Iām not too interested in grafana at this stage -> havenāt really worked with it before - probably need to look into it since everyone else is working with it
Rgds,
Wzz
Hi @Scrin, thanks for the pointers!
Iāll revert on this for others that might have the same line of thinking. *although, I wonāt call myself a HW dev at all, but can dig quite well and love to break things until they work 
Rgds,
Wzz
Hey @Motobiman.
Yeah, that was my initial idea - thanks for affirming! I havenāt checked which modules are available on the Ruuvi to allow some simple edge processing instead of harvesting all the data straight into a db thoughā¦ collecting is good up to the point your bank account breaks because of all the cloud space you occupyā¦
What are your thoughts on the collection process? @dgerman @Scrin, youāre welcome to jump in here if youād likeā¦
Rgds,

For my application, beehives, I need to be made aware of change rather than being able to look at days and weeks of unchanging data.
I would be happy if the whole system, how ever it is configured, worked in the background and was only powered up for a few minutes every quarter hour and ignored all temp, humidity, battery voltage and movement data within pre-defined limits but raised a red flag for that tag when its data went outside those limits.
The comms has to be over cellular networking as the collector site is remote without Wifi or mains power.
Frankly this idea of watching unchanging data, from sensors a few yards away from me, however pretty the page, leaves me cold, as for example if you miss a serious temp drop or movement in a hive, by the time you do notice it, the damage is done and often unrecoverable.
Data change and an effective warning of it, say by a text message to my phone, is what I need.

PS
Having a camera on the Rpi and being able to view the image over cellular network might save me a drive to the apiary site too.
Regarding Alternate processing: Scrinās description at 4/16/19 03:27 above and his excellent idea of providing the ability to provide the influxURL, makes routing to another web page process very easy.
I have had some ideas regarding the use of syslog to route the data see http://mybeacons.info/jakoavain.html
Regarding monitoring changes. I have noticed that grafana has alerts. As this is the best program I have seen in over 30 years, at least for processing data, It seems they have thought of that too, but I havenāt investigated how to use that.
Regarding remote site: Motobiman and his bees have got me so interested that I am pursuing using using http://www.uugear.com/product/wittypi2/ as per https://f.ruuvi.com/t/is-the-swamp-too-deep/3401
Hey @Motobiman.
I get it. I have the same kind of objective here with comms and notification. So, I like your thoughts.
With some of my other controllers that are running Node, I would pull the limits youāre talking about from my api to the device and then edit the broadcast loop to adhere to those limits - i.e. only broadcast when sensor data is in error. Hence,
broadcast loop every 1000ms => if temp >=< desired temp then do http request. The algo can be much complex than this, taking into account a sequential rise in tempā¦
This is all good in on some of the other stuff I managed to accomplish, but Ruuvi habitat is a bit new and still need to find my feet hereā¦
As soon as I have my setup up and running Iāll send through some thoughts on how I approached it!
Rgds,
Wzz
