TTN\LoRaWAN is not a very good fit for tracking stuff.
A GPS will not work in a lot of locations where you might loose your keys, so getting a location for the keys will be difficult.
And if the transmitting tag is at ground level (on a cat) the tag might well end up using long range mode, in which case you would be limited to around 24 position transmissions a day.
Hello guys,
Thank you very much for your answers, they are very helpfull for my thought process.
For the tracking part, I was more thinking on a give-me-your-position-upon-request rather than sending periodically the position.
I am not particularly interested in viewing the travel path of my cat but I am much more interested in locating him when he is missing for a few hours…
The same for the keys… I need to locate them only when I loose them.
I was thinking, maybe wrongly, that if I am using TTN, I would expand my coverage and then being able to locate the keys I might have lost during my week -end trip 300 kms away (provided that the TTN has local gateways to relay the signal…
ANd I like the idea of expanding the current network by adding my small contribution with my own gateway. I checked my living place and I am kind of at the limit of two gateways, which would permit to extand the coverage of the network.
Not a good idea, since LoRaWAN is like ALOHA, you don’t know that your message will reach the cat. Its better to have a history. Since it’s moving, there is a possibility that some messages will reach the GW.
Also LoRaWAN devices listen after uplink an only for two times in 6 seconds. If they listen all the time the battery will be over.
Unfortunately I don’t know for trackers with geofencing. Is someone knows, please post it.
If you want “deliver-ability” go to GSM (I don’t know about NB-IoT)
I suggest you to scan the area with a node with the help of TTNmapper. Check if you have enough coverage. For example in my area SF10 has 50% success. So, I use this. SF11, SF12 is forbidden, unless used occasionally. Just use SF10 or lower.
Funny idea. Get a mobile gateway to search for the cat in case of disappearance.
Since you seem adventurous guy, if you have the money to spare and the time, join us 
an extra GW is always welcome.
I have build a tracker, but needs upgrading to low power (almost done) and LMIC (todo). Next step is to enable geofencing. I promise I will share the code if you do the soldering. 
@LoRaTracker I disagree. I think with good coverage, TTN/LoRaWAN, is good enough for tracking, if it’s not critical / urgent.
I have my Dragino LG308
Is BEEP using TTN V3 already? They might not have migrated from V2 yet. You probably need to ask them.
Hi
I am actually see device update data every minute,which I setup interval on BEEP app.
and from BEEP app show Loraconnected., it look PCB is communicate with TTN V3.
Not sure where is missing
and when I try to backward to TTN v2, there are some information I need to configure on PCB, but not there are some item missing in BEEP app, such Device ID.
therefore I assume it is under TTN v3.

Hello,
Thks again for your answers. I have been reading here and there, thinking on my projetc etc…
I am not decided yet, I guess I need to think further.
The learning of the system interests me a lot but I am still unsure of my ability to do it.
Thks to you, I discovered Cayenne portal as well MQTT, maybe it can help to achieve more easily what I need.
I will keep you posted, especially if I activate a new gateway 
Which is not available in the v3 integrations and there is no visibility on when or if it will be - and the v2 console won’t be operational by the end of this year.
Thks for the warning descartes!!
I have the same problem / request and want to buy or build any cat trakker that is small, the trackers available are too big for small cat. I received an email in this forum with an offer to sign up to prepay the development for a cat tracker ; but the sender never replied to my email.
I can build simple electronics or develop professional software, here it is mainly open flat land with some houses here and there, we got a 10 meter tall building to install gateways/antennas.
For a cat owner it is not funny if the pet disappears for hours, it is nerve wrecking.
I am willing to cooperate on any project to build one. Just write me an email
Try this:
Excelent ! , I will ask them for more info, need a really small battery and probably custom made enclosure.
The antenna might be an issue with size , so will ask too about options. For the cats roaming around I guess the range is not a problem, perhaps 100 - 300 meters around the house.
This shop has many other interesting gadgets for other projects.
Thank you very much indeed
Hello MKlein,
Your project looks interesting!!
For the range, I would go for a couple of kilometres…
Indeed, the cats are covering long distances when they explore around the house…
Maybe you could take advantage of the necklace to extend the antenna…
Hi Everyone,
I am back on the TTN forum.
I have made no progress on my project, as I have been busy with other stuff.
I have abandoned the tags idea for the cat of for the keys… (Apple’s Airtags are here now…).
But I still have my gate issue. I need to monitor the status (open or closed).
I have explored Zigbee & EnOcean solutions, as I have both Zigbee & EnOcean UBS keys on my Jeedom box.
The issue is that door sensors are usually in-door use only. The only one external door sensor I have (EnOcean) does not work on iron gates (it kills the magnet signal).
So the only solution left I think is the Lora sensor, at least for the range.
I still need to validate if the iron of the gate will not cause the same issue as for the EnOcean sensors.
I envisage to buy a Mikrotik gateway, which seems to be compatible with TTN.
I need to identify the right door sensor. I have identified this one from Dragino https://www.dragino.com/downloads/downloads/LoRa_End_Node/LDS03A/LDS03A_LoRaWAN_Door_Sensor_UserManual_v1.0.pdf
Has anyone some experience with door sensors in external use?
Thks

You need a proximity switch.
Hi Peter,
Any model to recommend? I did not came accross such thing in my Lora sensor exploration…
Either a Reed switch or magnetic switch, I have used the Milesight 300-MCU (hope I recall the model correctly), 3 of them and all 3 worked seamlessly.
Same magnetic switch they use for windows in household alarm systems
Ok, thks!
I looked a bit for shopping the product, difficult to find it available…
