@Andreas Spiess: I had a little trouble running your SD card image, more specifically testing the mosquitto broker. I found that the broker would refuse connection without authentication and I had no idea of passwords set. I found I could change the configuration slightly to allow anonymous connection which inside my firewall for test is OK. I navigated to the configuration file and used the nano editor to open the file for edit as below root@DietPi:~# nano /etc/mosquitto/conf.d/websockets.conf I edited the line: allow_anonymous false to read -> allow_anonymous true Then saved the settings with Ctrl and O before I exited the file with Ctrl and X before a reboot to load the new settings. Everything works superbly, thanks again

I had great success with this on both a Pi-Zero with a WiFi dongle, and with a Pi-3. Thanks to both you and Peter for this contribution. But seeing that Peter added comments in the Christmas script in March about successful testing with a NanoPi M1 & M3, coupled with the fact that I've been looking (waiting) for a beefier alternative to a Pi-Zero, I thought I'd look into getting this working on a NanoPi. Well, looking no further than ArmWorks selling a NanoPi2 (only slightly larger than a Pi-ZeroW, but with a 1.4GHz Quad Core Cortex A9 processor) for $15-shipped, I experimented a little. Here are my findings: Well, all did not go too well. The first stickler was that the closest DietPi SD image available to a NanoPi2 was one on the DietPi website for a NanoPi M2. Outwardly, it seemed that the most significant difference was the lacking of an ethernet port on the NanoPi2--shouldn't be too significant, so I installed it. Everything seemed to be okay, except for two things. 1) upon booting and displaying the normal information before allowing user logon on terminal 1, the input was blocked. However, an Alt-F2 switch to terminal 2 got around that. Eh... not perfect, but workable. 2) when installing either LXDE or XFce, neither would work--seemed to be failing during X. But having gotten that far, the Christmas script seemed like halfway-good idea. Well, it did run... but with a generous amount of errors; mostly having to do with file-system access or something missing from the internet. It was minimally successful; Mosquitto broker worked, but the web server did not. So..... no ability to test further. Anyway, would you be willing to take a shot at this? I would gladly provide the NanoP2. Thanks.

Having the same issue here - It seems like Node-Red cannot access the internet. I tried to setup a Ping in Note-Red for "registry.npmjs.org" and "google.com" without luck. Then I tried from the Webmin and Putty directly from Dietpi, and still no luck... Somehow the Dietpi seems to be disconnected from the internet which is strange - I'll see if I can work more on it, but would also like to hear if others are having the same issue.

Very nice! I have been logging my solar data to Adafruit.io and now easily I can set up my own broker.

I had a couple of thoughts since you're using DietPi (my personal favourite). You can enter a hostname in dietpi-config and then you don't need to worry about the IP address so much. Also, Dietpi supports external USB memory/drives so you can configure a USB drive for all your user data. Its faster and less risky than writing to your SD card :)

This is not a surprise, because the dietpi does many adjustments during the first install (maybe also to the environment it runs on?). So, the way would be, to install your OS of choice and apply the script. It should run much faster on the -3 than on the zero.

The node libraries which Peter Scargill installed with his script made me curious, so I run it on a Rpi 1B last night. The script ran insanly slow on that hardware, but surprisingly the Node-RED server is running better than I expected. It takes of course longer than on RPi 3 to initialize the web frontend, but once it is down, the performance is enough to create flows and deploy them. I did not figure out why, but with the testinstallation done via Peter Scargill's script I was unable to add further node libraries. I think something went wrong with the npm setup.

Great eye-opener Andreas, thank you. To put this into context for myself, what you are saying is that you could set up your IoT home with as many wifi enabled devices as you like, and, as long as they can talk MQTT, for $20 and the price of a wifi adapter you can have this device log every possible event. It is stand-alone. It does not have any effect on how any given device behaves or reacts with its immediate controller, eg smartphone. Have I properly understood the context? is there another benefit? Cheers.

Andreas, I'm not having good luck with getting mosquitto to work properly. I built it using your image, configured wifi, but when I try "mosquitto_sub -v -t '#'" I get the error "Connection refused: not authorised" or I use MQTT.fx and I get "Not authorized to connect". I've tried it using both accounts. Node-RED also won't connect. What am I doing wrong? Thanks, I love your channel!

If you do not use passwords, you have to change the config of mosquitto: $ cd /etc/mosquitto/conf.d/$ sudo nano mosquitto.confand replace allow_anonymous false with allow_anonymous true

I personally wouldn't send the 'timeStamp' column in the SQL INSERT. I prefer to config the column as 'CURRENT_TIMESTAMP' in the PhpAdmin, and it will write the timestamp by itself. I prefer doing this because it's easier, and pretty useful for iot applications where using less code can also be trivial. I have to say that I really like your content and this video made me learn more things :). Life's about learning.

Thanks for your video! Would your image also run on a Pi1? I still have a lot of them around and barely use them.

Maybe you try? Otherwise, you have to install dietpi and apply the script.

Nice video I will try DietPi for sure. One note you can enter the wifi password without a monitor. Solder headers to the Pi Zero and connect a FTDI adapter.

Hey Andreas, I just installed Pete Scargill script on a clean Rasbian lite image. I would like to make a backup of the SD card, but the backup that I make with Win32 image writer its 8gb, and If i try to burn it on another 8gb sd card its bigger by a few KB... How did you manage to make that image ?

@AndreasSpiess

I had to find the smallest one. They all are a little different.

What about corruption of SD card because of writes to the database? Would be nice if you could make a video on how to temporarly save values into RAM for a few hours, and then flush them into the database, so it would write only twice or 3 times a day to the sd card.

I too have no idea how to use the Pi's flash memory but it is also relatively easy to mount a storage device to USB and create your database on this storage or to mount a network storage to your Pi. For example; on my existing Pi board which is permanently installed inside my home security alarm system I have gradually come to depend on many Node-RED flows and many MQTT subscriptions to the broker all hosted on this very old Raspberry Pi with the weak link probably being the SD card in this Raspberry Pi. For this reason I have the following in place: 1. I have my 2TB NAS drive mounted on my Pi from reboot (I use cron to run a bash script on boot which will "sudo mount -a" mount all drives listed in the file system table "fstab") 2. I use my NAS drive as storage for any data, logs etc to reduce write cycles to the SD card and provide data contingency/redundancy. 3. I also use "cron" to run an other bash script which creates a compressed backup of my SD image once per week at 2:30am on Tuesdays so I can easily flash a new card if I have a SD failure I am more than happy to document this if Andreas or one of your subscribers would like to create a tutorial, just ask?

msevyt I think that each bit on the SD card has 10,000 writes and I'm pretty sure it balances out the writes to the different bits. But if you wanted to achieve something like this it would definitely take some coding or googling to find the solution.

Been through a bunch of videos. This is the one I want to work more than the others... Has what I need. Thank you. This, being my first attempt using Node Red (New User), I feel I've done well just getting to this point... I'm stuck. The dashboard is requiring Authentication. Is there a fix?

I was close to moving on. Didn't expect an easy answer to this issue. You saved the day.. er week or month. Thank you.

I use Raspbian Lite in a similar matter and I found out that the HDMI output is switched on, even if there is no screen attached. Switching this off saves power and reduces the CPU temp, I read somewhere that it can reduce 20% power. To switch off the HDMI output type "/usr/bin/tvservice -o" and add this line to "/etc/rc.local" at the end, before "exit 0". I don't now how this is set up in DietPi.

I found out that switching the HDMI port off reduces my CPU temperature (at room temperature) from about 31.5 to 29.5 deg C. I don't know ho to relate this to power use, but it must be a relevant amount.

Is it possible to get the Hello World script in Node Red ?

Thank you again for another in-depth video but need some advise I would follow this for MQTT broker but have heard that the memory card on the Pi fails after some time and stops working so reliability is not good is there a better way to make the broker, please? thanks Bob-UK

Hi, is it possible to change the WiFi credentials in a headless setup using a pi zero w? After I write your image to an SD card I change the credentials in dietpi.text and modify it for WiFi enabled but I can't see it on my local network. Oddly when. I make the same changes to the same file using a raw image downloaded from the diet pi website I can see it connecting to my local network and have no problem ssh' ing into it. Any thoughts?

at time sync 3:41 you show a wifi doggle. I thought Wifi was built in? The reason for the question is I am getting eth0 not found both with the doggle and without. Trying to figure out how to connect the keyboard,mouse and wifi.

How can you control devices from external (3G network) if your broker is inside your local network? I think is better to use an external broker. What do you think?

@AndreasSpiess

6 жыл бұрын

There are two different things: One is the broker and the other is GSM communication. Both are somehow independent. You can choose the location of your broker behind your firewall or in the cloud. Keep in mind, that many small devices cannot use HTTPS for communication. And you have to find a way to receive the GSM messages with your own device. Or you connect to a service with your Mobile. If you build your own device, it is probably behind your firewall, if you connect to a public web service, it is in the cloud.

Andreas Spiess I am a software engineer and what you explained was clear. I wasn’t talking about SMS or some like that but internet from outside the LAN. Mobile 3G was just an example. If I am outside the lan and so I can’t reach the broker... how can you read values from your sensors? I was wondering if it’s better use a broker on cloud.
