Hi all
Please forgive the blatant advertising, but hear me out!
I’m Al, part of the Edinburgh community in Scotland. As a community we’ve added a bunch of gateways to TTN over the last year and been out mapping. I’ve installed two permanent gateways myself, and a bunch of other test ones. With a combination of DIY IMST and RPi gateways, Laird RG186 and others and we now have pretty good coverage over the city, with more to come.
One of the biggest problems we had was actually getting hold of stuff, particularly suitable antennae and decent quality cables. I ended up importing antennae and other bits and pieces through my company. We’re in the process of building LoRaWAN nodes, but in the meantime I thought it would be a good idea for us to properly import and resell some of the gear we have tested and installed from here in the UK. I gave a talk a couple of months ago and lots of people were asking where to buy gateways from, now I can tell them! It’s connectedthings.store!
We’ve started out by selling my favourite LoRaWAN things, including LORIX One and Laird RG186 gateways and Sirio antennae. The Laird gateways are really easy to use and reliable, and one of the Edinburgh community members has installed more than five around town. I’ve used Sirio GP 868 C antennae and been really impressed with the quality and range (see Edinburgh on TTN Mapper, I’ve installed them at two sites so far), so they were definitely on the list for the launch stock.
We also have a selection of pre-made low-loss RF cables, including SMA to SMA or N cables in different lengths, with more options for arriving coming soon (including pesky RP-SMA…).
We’re starting out with small quantities of everything, but I’d really like to ramp this up and stock more and more LoRaWAN kit, so I’d be keen to hear if people have any suggestions. We’re based in the UK so everything is priced in GBP, but we’re happy to sell everywhere we can. In fact our very first order was from Romania!
As a launch offer, we’d like to give 10% off to the first 10 people who use the discount code TTNTEN at https://connectedthings.store
Thanks for listening, we’re just a two nerd company at the moment, and really want to see TTN and LoRa grow, and grow alongside

Tom, we developed a robust workaround for your particular use case using a device fit for this: it embeds a real time clock and you can set recipes to open/close your irrigation valves independently from the UL frequency ! check this out: http://www.stregatechnologies.com/product_list/extreme-range-wireless-emitter-irrigation-valves/

Hi all. We just released the v2.0 of our iC880A Raspberry Pi backplane 
https://shop.coredump.ch/2018/06/15/the-coredump-ic880a-backplane-v2-0/
Quick summary on what’s new:
- New more accurate temperature/humidity sensor (Sensirion SHTC3)
- Fixed-voltage DC-DC converter (6.7-28V input range)
- Reduced height due to better stacking headers
You can find the rest of the details in the news post linked above.
We have deployed a v2.0 backplane (powering a TTN gateway with passive PoE) on a rooftop in Rapperswil two weeks ago:
You can view the monitoring data it collects on our public Grafana dashboard.

And use it at your own risk.
An ATMEGA1284P, when run at 3.3V has a max clock specification of around 12Mhz. Using a 16Mhz clock (as advertised) is outside specification.
Yes, you are right because the datasheet recommends as you say. We tested both 8Mhz and 16Mhz and both have been working fine for 5 months.

@BoRRoZ I have to try, but it suports OTAA. So I think it will be not problem. At the moment we are using ABP with specific prefix on our servers and work like a charm. I will try TTN with next device.

I did last month a very nice experiment with chicken door. Works pretty easy with IFTTT integrations (for TTN only callback and IFTT filter will be different) - so it is possible to recieve sms/email/fb mesegger allert if door are closed/open during the day.

New MBUS node is working - specialy for Landys+Gyr heatmeters.
It also possible to use MODBUS RTU, S0 counter, Voltmetr and RHT.
Prepared for DIN mounting and powered from 3,6V battery, stepdown (5-100V) or solar power.
Mainboard based on KETCube I have mantioned 2 month ago.

Greetings, fellow Earthlings!
We are Grey Cat Collective and we squat on the outskirts of Shenzhen re-purposing e-waste.
For our latest project, we decided to tackle the LoRa topic. Here’s what we have put together:
Frustrated with monthly fees, and with a deep distrust of the telecom industry, we approached LoRa as an opportunity to build a community driven communications network, with the LoRa Text Development Kit being the end node for a user interface with most. But we came here to the TTN forum because ya’ll like to get into the details, and thought you might appreciate the device as a portable debug console for your LoRa project, or a remote control/monitor for the sensors you have around your home. We’re excited to share this with the community, and see what you can come up with!
We sell these devices on our website greycat.co and on our Tindie store. The schematic and other documentation can be found on our docs page docs.greycat.co.
Some quick hardware call outs include:
- AtMega 2560 (Arduino/AVRDude compatible)
- 1.8" TFT Full Color LCD
- RFM95
- MicroSD card slot
- DS1308 RTC
- Snap Dome Keypad
- Trackpad
- BQ24075 Power Management IC for seamless switching between LiPo battery and shore power!
If you are outside of the United States, contact us directly at meow@greycat.co and we can work out a deal for shipping fees.
Feel free to use the same email for any questions, concerns, or random outburst of creativity! All are welcome!

- is the complete working code open source… where is it ?
- is it a mesh network… can you explain how it works ?
Hi BoRRoZ
- is the complete working code open source… where is it ?
A. We’ve only recently started working on software development. We’re currently a couple folks working on this in our spare time. So no, we don’t of a fully fleshed out OS. For this reason, we sell this as a dev kit on tindie rather than a finished consumer product. We are, however, a few days away from a bare bones messaging app that can run on the device. This software, and future software, will be open source under the Apache 2.0 license. We will post link to github repo when pushed.
- is it a mesh network… can you explain how it works?
A.For us, yes. Our goal is that each device can contribute to the larger network. However, what you do with the LoRa Text Dev Kit is up to you. Upload whatever software you’d like to it, and it seems you can decide for yourself if and what networks you decide to contribute to.

Hello!
I’ve been busy working for Pi Supply, a UK Based Raspberry Pi retailer and we’re glad to announce the launch of our LoRa Gateway & Node Kits.
We’ve launched it over on kickstarter at https://www.kickstarter.com/projects/pisupply/iot-lora-boards-your-gateway-to-the-internet-of-th
The gateway is based on the RAK833 and nodes on the RAK811 with the goal being that we provide high level guides on setting up and getting going with the devices.
