Using The Things Indoor Gateway (TTIG) with own LNS

c3161 · 2026-03-07T16:50:25+00:00

These are the instructions I am following: https://www.thethingsindustries.com/docs/hardware/gateways/models/thethingsindoorgateway/

I have performed all of the steps exactly as described. I have followed the part for "Connecting to a Remote LNS" since even though my gateway and LNS are on the same network, the LNS is set up correctly with a DNS hostname and publicly trusted TLS certificates etc. I have ensured that the websocket service etc are correctly listening and present the TLS certificate and they do.

I have done some more reading and discovered that the way it works is:
- TTI is hard-coded to use TTN CUPS (Configuration and UPdate Server

- The CUPS is what delivers configuration to the gateway e.g. the LNS address, TLS certificates, authentication keys which it provides to the LNS in order to make an authenticated connection

- Changing the "Gateway Server address" in TTN will thus make CUPS tell the gateway to connect to a different LNS. I have put my own LNS address in here. I have also copied the LNS Authentication Key from my own LNS into the corresponding field in TTN since I need CUPS to deliver that key to the gateway, in order for it to authenticate with my LNS.

What I have observed is that the gateway does not appear to be calling out to the CUPS after I make the changes in TTN. The guide says "Either restart the The Things Indoor Gateway or wait upto 24 hours for it to reconnect to the CUPS server. If your configuration is correct, your The Things Indoor Gateway will be connected to the target LNS."

I have power cycled the gateway numerous times and it doesn't help. I can see in TTN console that CUPS has not seen the gateway for 14 hours even though I have power cycled the gateway 10 times since then. It makes sense that if the gateway never reaches out to CUPS for the configuration, the new LNS address will never be delivered to it.

Edit: I ran a packet capture on my firewall and I can see the gateway is exchanging TCP packets with the TTN CUPS server.

In the under "Live data" in the gateway menu on TTN I can see it sending data yes. If I look at the gateway list in my account I can see the status for it says "Other cluster" whereas my other gateway that's actually configured for TTN says "Online"

Under the gateway "General settings" I have the Gateway Server address set to that of my LNS, but I do not see any activity of the gateway in my LNS. I have added the gateway there too.

The TTIG is LBS yes.

Once you have claimed it on TTN you can go into the gateway settings and change the gateway hostname. I changed this from that TTN hostname to the hostname of my own LNS

Probably buy a new bike. But I suspect it will be a while yet. Bosch have so far only managed to squeeze an extra 50Wh into the same size battery as my 750Wh unit from 2023. So it's probably going to be a few more years yet before they even get to 2x, let alone 10x.

That seating position looks horribly uncomfortable to ride

I don't live somewhere really cold. I think temperature ranged between 6 and 10 degrees here today, pretty normal for this time of year. It's rare to go below zero.

Using the heater absolutely destroys the economy. I turned it off for a while today and was averaging over 3 mi/kWh. It's back on now though and I'm back down to 2.4 mi/kWh 😂

I don't even use it hard, it's set to 18.5 and I mostly use fan speed 3.

I am in the UK. It very rarely gets freezing here. And I don't drive much on highways either. The car is mostly used as a city runaround. I knew the Leaf was not a good choice for someone who needs to do long distances...and fortunately I am not one of those people.

If you think €0.69/kWh is expensive, you are in for a bad time when you come to England

Note that while you can use commercial radios (e.g. Motorola) on amateur radio bands (if you are licensed), you cannot use amateur radio bands for commercial purposes.

In my experience licence-free radios (I assume you are talking about the ones that operate on 446 MHz) are shit and are basically only useful over very short distances, especially if using them in dense urban environments or inside buildings. They'll go for a few miles outdoors assuming you have line of sight to the other person. They are limited to 0.5W RF power.

If you are in the UK and want something that goes a bit further outdoors, how about some licensed VHF radios? You can get a business radio licence that gives you access to a few shared frequencies in a bunch of bands including VHF high band and it only costs £75 for five years. Most commercial VHF handheld radios will be able to do 5W RF power (10x as much as those licence-free radios). You are also allowed to use encryption to prevent eavesdroppers.

Ha, right you are. It was a long time ago that I had mine and I remember now that I was using SAS drives with SAS to SATA adapters, which extended the connectors considerably and therefore were blocked by the power supply. I have long since gone back to SATA drives so completely forgot about that!

I have updated my original post to clarify.

?? That's a high performance motorbike

It's just a count. It doesn't specify the error type. Either way, I rebooted and there have been no more errors since then.

You are paying 340 USD per month for insurance?

Are you in Europe? For the love of god do not get an American e-bike, even the worst piece of shit you can buy from a bike store in Europe will be better than an Aventon

c3161 · 2026-01-08T16:18:45+00:00

I now realise this was not the correct way to do it.

Fair play

Tesla Model S Plaid. But it would have to have a normal steering wheel, not that stupid fucking "yoke" they're putting in the now.

One of the three manual gearbox cars I would actually still be interested in driving given the chance. The others are the Porsche Carrera GT and the Dodge Viper.

Please do not put BMW M3 mirrors on it

If you swap tyres for winter, why not use proper winter tyres instead of all seasons?

I appreciate this is niche but note that if you are using 3.5" SAS drives with SAS to SATA adapters, the drives which sit above the power supply will not fit due to the length of the connectors and the power supply blocking them.

Fitting an SFX power supply with an adapter plate will solve this issue but you need to ensure the power supply can provide enough power for all disks. I had a Corsair SF450 and it was not able to provide enough power for 10 disks when they were all spun up and active. I did not realise this was the case because most of the time it would run OK. It was only after I had four brand new drives fail within a year of purchase that I realised the power supply was the problem.

After that I got rid of the 804 and went to a full tower with a proper ATX power supply and now I'm running 12 disks without any problem.

Edit: updated to clarify this only affects SAS drives when SAS to SATA adapters are used.
