Hi All,
New to lorawan and hoping for some assistance.
I am using Dragino LWL01 water leak sensors for our upcoming project. 227 sensors in a townhouse complex.
I wanted to know if I register them to TTN in our facility where I have a laird gateway set up already, will they work at our project site where I plan to relocate them? I have a separate Dragino Outdoor Gateway set up there.
Will they automatically connect to the site gateway once I bring them there?
Thank you in advance!
Contrary to things like WiFi a LoRaWAN node does not connect to a gateway but it connects to a network. This means a LoRaWAN node will be able to exchange data as long as it is in radio range of any gateway that is connected to the same LoRaWAN network.
Relocating the sensors will not be an issue if both gateways are connected to TTN. However there is one thing to take into account, the LWL01 uses ADR which means after some time the node will be instructed by the network to use an optimal transmission speed and power, these settings might not work at the new location if there are more obstacles in the radio path. The node should retune for the new location however that might take some time. Resetting it using the switch inside would be a better solution.
Hi Kersing,
Thank you for your feedback, it is much appreciated!
This is somewhat of a pilot project so we just need it to work for a year until we finish our own proprietary system. Once we are ready we will be swaping our customers to our network and gateway.
Yes, both gateways will be connected to TTN so it looks like you answered my question. I will set them up at our facility then transport them to the site for installation. Once I am there I will open the cover and hit the reset button.
A shame to read you won’t be using and contributing to TTN in the future.
We will still us TTN as long as it works for us. I was referring to our nodes, gateways and platform.
You may want to consider how this sounds & feels for a community network.
Hi Descartes, how does this sound and feel?
To me? I’ll phrase a commercial variant of the quoted statement:
“We need a quick solution, we’ll place a big enquiry with Aquazen Systems, get a great price for a few installs in the first phase and then when we know how to do it, drop them”
Or to put it visually: https://youtu.be/9zl1fTkpSCE
I’m the principal of two businesses so I really know & experience this every few months for the last +25 years.
In some random ideal world, which if we don’t all strive for, will just let things slide & decay and we’ll all end up in chaos, individuals & companies make use of the TTN infrastructure, contribute to it and if they need to move on, leave an ongoing positive legacy.
In your particular instance you could join the TTN Concord community and setup an external gateway at your office providing coverage for the Vaughan area of Toronto, as most of the current gateways are on the south side of the 401. That way you have a gateway for testing with and a public benefit.
Then give a few basic devices to schools in the area. Great for corporate social responsibility and subtle PR. Even better, get staff to do an hour a month each in local schools on practical projects for students, your product / service is very well suited to that sort of thing and can expand STEM topics with such things as geography when linked to WaterAid overseas projects. This is great staff development and a great deal of fun working with enthusiastic & enquiring minds. And it’s more than CSR, there is a world wide shortage of engineers, where will the next generation of employees come from. So perhaps consider a project with your local university.
Do I do this? I’m in the fortunate position to have three really deep niches I work in where I’m the UK’s best choice. So I can afford to allocate 4 to 8 hours a week for community activity, mostly in schools, as a volunteer ambulance first responder and as a deployer of gateways. I contribute here a bit as well.
So, please please think of us as some friends that can help you achieve your goals, and as you’d treat friends, don’t just hang out whilst it suits. And do not underestimate the internal & public benefits of being an engineering firm active in its local community.
Hi Nick,
I completely understand what you are saying, and I respect your experience. I am very new to this and learning as I go.
I’d be more than willing to hop on a call and discuss how and where I can get more education on Lorawan, connectivity, frequency, and how it all works, especially the current challenges.
If this is something you provide I would be happy to learn more.
Cheers,
There is a wealth of material to be found on the TTN docs section that you can review at your own convenience, links below.
For technical things for which there may well be people in your area who’d love to help get you started. A phrase with some complications, but “charity begins at home” - there are TTN communities on your doorstep and with the current global work situation, maybe some people who would appreciate a small consultancy gig in your area.
I was focusing on the community aspect of TTN given that it is a world-wide resource, central servers provided by The Things Industries and gateways made available by numerous individuals, organisations & business. Part of that was highlighting how being involved in this & your local community can be good for business in other ways.
The two principle technical resources are:
Read all of:https://www.thethingsnetwork.org/docs/lorawan/
The devices section of: https://www.thethingsnetwork.org/docs/devices/
The gateways section of: https://www.thethingsnetwork.org/docs/gateways/
The network section of: https://www.thethingsnetwork.org/docs/network/
The applications and API sections of: https://www.thethingsnetwork.org/docs/applications/
and plan to do
https://lora-developers.semtech.com/resources/lorawan-academy/
After a first reading of the TTN docs, there is no substitute for getting a gateway and two or three different devices, getting them going all the way through to a dashboard, chart, alerting system etc.
Then go back and reread the TTN stuff and get stuck in to the LoRaWAN Alliance material.
And for any clarification or if you get stuck, the community is here to help you figure things out, not always with direct answers, it is better to teach how to fish rather than just be an online fishmonger.
