In a previous post, I’ve been introduce my home made LoRaWan solar powered outdoor gateway. I’ve been investigating on the minimal hardware to make it running and reach some interesting result in my garden ;). Now it’s time to deploy the gateway on the field (basically on a roof top) and this means I’ll not be able to continue to learn what how it evolves over time.
For this reason, I’ve made a small project to monitor the main elements I want to track about this gateway:
- Battery Voltage
- Battery in & out power
- 5V powering availability
For this I’ve selected a simple and LoRaWan all-included Arduino platform I already detailed in a previous post: the LoRa Radio Node. Let’s detail this project now available on github.

I’ve published a post in January 2019 on a solution to alarm you TTN gateway. It was based on noc API but these API have been deprecated. It means this solution is not working anymore.
So I’m investigating some new solution: the more relevant is the use of TTN cli solution.
Let’s seen what can we do with this.
I’ve been talking about this ultra low cost LoRaWan gateway in last October and ordered one. The time to get it has been long as it has been arrived in February this year. This sounds due to an early ordering as the product is now available, even on Amazon for a price under 180€.
This price is not so low if you compare to a Laird Sentrius but we are not talking the same product ! Here we have an outdoor gateway with PoE powering. That’s really interesting. The only missing thing is a LTE communication.
This gateway exists in two different version LoRa8 for 868Mhz zones and LoRa9 for 902 MHz zone.
Let’s see it in detail and find how to configure it for joining TTN.
Today was the first day of The Things Conference (TTC) 2020 in Amsterdam. TTC is the yearly event organized by The Things Network initiative. Years after years this event is becoming THE world LoRaWan event. The Things Network let the floor to The Things Industry, all the LoRaWan industrial ecosystem is coming to Amsterdam to discuss about the future of this LPWAn technology. The community spirit is still here, strong and awesome: I had plenty of discussions with many tech & business guy I never met before ; I’ve learned a lot of thing through the high quality conferences. Two days of conference will be too short for meeting people I’ve listed and follow the conference track.
So let’s talk a bit about the content of this first days and the direction The Things Industry is giving to LoRaWan ecosystem. Because, trust me or not, even if the LoRaWan alliance is full of big telecom companies, it really seems that, this small group of 20 awesome people from TTN are taking the lead.
The Things Indoor Gateway (TTIG) has been announced and distributed during the TheThings conference 2019. Since it was impossible to get some, victim of its success (and the little initial stock). From mid-august it is now possible to get some and I’ve bought one as soon as possible.
The Things Indoor Gateway is a low cost (70€ – 90€), 8 channels (EU868 full gateway), LoRaWan gateway running on TheThingsNetwork. You can’t expect a large coverage with a such solution to be used for city wide network but it will be perfect for covering a large house or a small building where you want to deploy LoRaWan sensors.
The LoRa Radio Node is an AVR Arduino board with a RFM95 LoRa module. This all-in-one LoRa module allows to have a LoRaWan device for a reasonable price around 15€. You need to add a battery (like a LS14500 3,7V battery) on the battery holder for a 4€ extra cost to make it mobile. LiPo option are also available using the power connector. Even if the connectors are looking like grove, they are not compatible so you will have to make your own wiring to connect extensions.
This post is reviewing how to getting started with this board to fire your first LoRaWan frame over The Things Network.
There is actually no solution to get an alarm when a TTN gateway is shutting down. That said, all the information are accessible thanks to the different API.
To monitor my deployed gateways, I’ve made a little script in python working with IFTTT. It connects to the The Things Network api, get the gateway status and call the IFTTT webhook in case of last gateway update too old.
On IFTTT i’ve created an applet to generate a Push notification on phone to get the alarm.
The script is accessible in the post detail.
