Tot voor kort had ik 2 verschillende LoraWAN nodes in huis: een tweetal LoPy‘s, waarvan er eentje dienst doet als single channel gateway en een Marvin. Beide zijn niet bijzonder goedkoop, een LoPy met ontwikkelbordje en antenne kost zo’n 50 euro excl. verzendkosten. Een Marvin kost bijna 85 euro excl. verzendkosten. Niet echt sensoren dus die je ergens “kwijt” wilt raken. Terwijl een […]

Zowel in Amsterdam als in Venlo worden tijdens de jaarwisseling de fijnstofniveaus in de lucht gemeten op basis van betaalbare meetstations die je zelf kunt bouwen.
In the Netherlands, KPN was the first to offer nationwide coverage of a IoT network based on LoRaWAN. You can read about my first tests using their Network in combination with the Marvin node in this post. Unlike with the IoT network that for example is currently being rolled out by T-Mobile, which uses NB-IoT and different hardware than The Things Network (TTN), […]
At AliExpress they sell a number of cheap GPS modules that you can use for Arduino. I ordered one (this one) GY-NEO6MV2 for €6,82 incl. free shipping (the seller doesn’t offer free shipping anymore so you might want to shop around a bit) and wanted to try it out on the LoPy. Now, I wanted to say that using it is really easy, […]
I still wasn’t out of “what if…” scenario’s for the devices I had been playing with in relation to The Things Network / LoRaWAN. Because, although I had used the WiFi (and of course LoRA) capabilities of the LoPy a lot, I had not yet played with its BLE (Bluetooth Low Energy) capabilities. For that I needed something else that could […]
What happens if you take a LoRaWAN node with you in a train while you travel across the Netherlands for about 2,5 hours? I did not know and wanted to find out today because I had to be in Zwolle for a meeting. So I charged a big external battery (with 2 USB ports), drilled a couple of holes in a […]
One of the challenges left with regards to the LoPy was to find a way to actually connect sensors to the node. I had little luck with the DHT11 temperature/moisture sensor (one of the drawbacks of MicroPython over regular Arduino code is the lack of libraries) and didn’t have any I2C sensors lying around. But I did of course still had […]
At the moment, the console page of The Things Network has some problems getting the Gateway page. It has been reported on the forums, it appears to be a front-end thing, the gateways themselves appear to be working just fine. So unless you want to get info about your gateway, add a new one, remove or change one, there should be […]
