How to Build or Migrate Sensors and Gateways on TTN LoRaWAN V3



LoRa and LoRaWAN are remarkable technologies, they have a long-range and low power consumption and therefore are ideal for our sensor projects. Today I will show you how to build a LoRaWAN sensor and connect it to the open The Things Network in the new version 3. I will also show how you can migrate your infrastructure if you are already a user of the V2 network, where the deadline is this December. In the end, you even will get a surprise. A lot of exciting stuff!

    My newest project is simple. Just a simple ESP32 or whatever with GSM and a single button… it is for my mother,. When the button is pressed it will send an email and an SMS to report an emergency. It can call me and the emergency. Makes a lot of sense. It can easily be altered to make a children tracker. GPS modules are cheap these days.

    Thanks a lot, I've upgraded my gateway but had no idea how to update my sensors!

    I'm not happy with the rise of the Helium Network (I saw your video about it and agree totally with you. Other videos seems surreal in their expectations. Helium seems unserious to me). For myself I'm unhappy with the decline of the TTN/TTS network. While you will made your video there was 21.3k Gateways as today there are only 21.0k left. I can not remember that exact but I think I saw 120k or more last year. I'm an operator of a TTS V3 gateway (and I'm with the network since longer). One point that annoyed or disturbed me is the migration process that The Things Industry have been chosen. The Technology is not so old but they discontinue the use of ABP. In the Forums one can read the comments about users that have inaccessible nodes that either will not rejoin by their self even if they are OTAA or they use ABP and this will mean that those nodes are lost or useless. I will stay on TTS but the next step is to bring ChirpStack up and running as a potential backup for two reasons: there are outages of the TTS network that also concern my nodes on my property. And the other reason is the potetial death of TTI. If you can make a video about it (ChirpStack) this would be great (and a help for people that have ABP-Nodes running an who can place a own gateway with a future private network in the area where their "old" ABP-Nodes are located (for myself I only use OTAA). Currently I ran a Dragino LPS8 as the operational gateway for TTS but the RAK with an "old" Raspberry seems interesting platform to experiment with ChirpStack on it. I have build sensors on myself following your recommendations and I'm happy with STM32 based CubeCells but i want to measure battery status. Currently I search for a good circuit to do this (maybe a simple voltage divider that is switched at the bottom for the short duration of the measurement).

    Excellent video, I really enjoyed it. Very interesting and I'm looking forward for the next one when you cover more of the Helium network. Maybe I'll get rich after that one…

    Maybe a delicate point but isn't updating the protocol with no back compatibility going to destroy confidence and limit uptake. Hope they can keep it stable for many years now.

    Are these sensors good enough if we sit in the first row?

    Excelent informative video!! How can I use the "Low power Atmega1284P based Arduino Lora node" with 915Mhz Andreas?

    Great overview. One thing: Jobs always said: "One more thing" not: one last thing. Perhaps the Apple lawyers already got to you?! 😉

    Excellent summary on the subject of LoraWan / TTN V2&V3. Short and concise! And thanks for the reference to IoTDevices: the device is now on my wish list. Unfortunately, I can only click the thumb once…

    I have noticed that car insurance businesses know the autos which are at risk of accidents along with risks. Additionally, these people know what sort of cars are prone to higher risk and also the higher risk they’ve already the higher the particular premium charge. Understanding the straightforward basics connected with car insurance will allow you to choose the right type of insurance policy that may take care of your requirements in case you happen to be involved in an accident. Thanks for sharing the particular ideas on your own blog.
