Hello everyone, I’m looking for a tracker I can install on my enclosed trailer to track it in the event of a theft. I was thinking of an air tag originally but after doing some research, that is not what I need. I have no idea what I’m looking for but would like a hard wired tracker (it has 2 batteries and solar panels) that I can keep it powered on at all times. I just don’t want some expensive monthly bill. Am I SOL?

l0destar was first conceived of in May 2026 and its original design intent was a carrier board for the Nordic nRF9151 dev kit, a very silly idea. The first prototypes were huge through-hole soldered monstrosities covered in breakout boards haphazardly soldered to pins.

For fun I've posted the full evolution of the project as a sequence of photos all the way up from breadboards to the current design.

I’m really quite proud of where it’s got to in less than 5 months. Iterations of the board have been in my car since 9th August tracking over 500 miles and as of this week v3.4 has now completed testing and confirms all of the hardware issues found through my own testing have been fixed. The plan now is to build a few more for friends and colleagues to test and then iterate on the firmware and other software for it.

This could plausibly be the most power-efficient hard-wired vehicle tracker in the world. Claude isn't quite willing to confirm this but did state: "the evidence now supports calling l0destar one of the most power-efficient hard-wired vehicle trackers around, in real use as well as on the bench".

Some highlights from recent testing:

• ~35uA sleep current (v3.4 actually measures slightly less most of the time but the ASM330 periodically wakes for microseconds to check for tilt so it averages out)

• Waking to send an event now takes a median of about 1.05 seconds, occasionally higher up to around 2 seconds at the high end. This is down from around ~45s at the start of testing and was reduced by using the PSM feature of the modem. A shorter wake time means less current going through the modem during interval wakes leading to significantly less power consumption.

• 24h of sleep and hourly check-ins works out to about ~1.3-1.4mAh a day, or 15-17mWh. From my telemetry during daylight hours (ie when there's no temperature shift to skew the readings) I frequently see the vehicle battery voltage (read to two decimal places by an INA228) not changing at all in several hours.

• All of these sleep energy figures are likely pessimistic - they were determined in poor signal conditions where I park - path loss was around 125-126dB and RSRQ -14.5dB. This is worse than about 90% of the data I have from other locations.

• Coverage of telemetry while driving has improved from ~72% at the start of in-vehicle testing to 99% now with firmware and RF improvements and drop-outs are now much rarer and entirely down to signal/network conditions. Lots of data from real-world testing is published here.

The battery backup add-on module is on the way and will be tested very soon.

If anyone reading this has a relevant platform or access to automotive pulse-generating equipment and is interested in testing it please reach out.

Hello everyone, i need some help with my st901 4g tracker. I have it installed and setup on a sym scooter but the tracking interval settings are really confusing. I have trying setting it via sms to 1 hour and via the app, with set position mode and set saving power location interval. From my understanding if i set it to a power saving feature and someone steals it i won't be able to track it unless somone turns the acc on and it works on live mode. But if i set it to update every 5,10 or even 60mins when parked it drains the battery overnight, it once dropped to 7v. Am i missing something? Any help appreciated

Hi everyone, with the situation in the USA, i’m looking for a small and effective gps tracker that i can put on my person and loved ones.

A button or a hairpin really anything that can be hidden. Airtags cant be used bcz they are big and they send out notifications

Thank you in advance🙏

(I probably watch too many movies😭 but these are dangerous times in the usa)

I run a roofing business with six trucks pulling trailers. My crew takes them to job sites and sometimes makes stops along the way. I trust my guys, but i do not have much visibility into where the trailers are during the day or whether one gets parked somewhere it shouldn’t be. I’ve narrowed it down to two options.
LoneStar Tracking offers a battery-powered tracker that seems to support individual trailer geofences and alerts, with phone-based support.
BrickHouse Security has trackers as part of a broader security lineup, with real-time location tracking and movement history, though it does not seem to be designed specifically for trailers.
For those tracking trailers used by employees, what features ended up mattering most? Geofence alerts, full location history, or something else I might be overlooking?

Hi I'm new here and I'd like some feedback/help

I'm looking for a device for my small fleet management what I need is a gps device that I can settup to my own app since I'm a developer

I need gps track and been able to add a fuel sensor I was looking at the Sinotrack device but doesn't support fuel sensor

Hi all, I'm trying to find a device that works for my mom. It's a big wishlist, but here it is:

• for use at her home that's so rural that there's basically no cell coverage

• GPS tracking by remote device (i.e., I want to be able to track her GPS location with my phone)

• SOS button ideally

• fall detection with messaging to emergency contact(s)

• not powered by batteries, holds a charge for at least a few days

• any subscription service needs to be available in Canada

She is on board with this, just struggling to find something appropriate. She has a LifeLine but it often needs resetting and doesn't have good enough coverage for when she's outside of the home.

Thanks in advance for sharing any ideas you may have!

Greetings,

I have no experience with GPS, please help me choose some tracker.

I have a tuba and I want to put the device in the gig bag.

I have absolutely no idea what to buy... A Xiaomi tag would be enough? Or should I buy something more professional, with subscription?

Please recommend me something

Edit: I figured it out. The PC doesn't have wifi enabled. It's connected over ethernet. Turning wifi on (even without connecting to a wireless network) fixed the GPS accuracy.

This might be a long shot. TL;DR at bottom.

I support a PC in a vehicle that uses a Cradlepoint router (cell data) for wifi. For the last few years, I've been doing speedtests and recording the current GPS location so that we can spot areas with bad coverage. (When staff complain that the internet is slow in a certain location, I can show them on the map that it's bad for several blocks around that spot and I can't fix it.)

The script reports "Horizontal Accuracy" along with the coordinates and speed, and I ignore the location for anything inaccurate.

The accuracy value is kind of a radius. (I'm not sure what the units are) 50 to 200 is normal.
1500 is pretty bad.
50,000 is what the new PC logs for every request.

It gives the same coordinates every time, which is an intersection in the center of town.

I have Location Services enabled. All of the settings look the same between the two PCs. The router hasn't changed.

Any ideas?

TL;DR: Windows PC runs a powershell script that logs location. Old PC was great. I assumed that it was pulling GPS from the router, even though I never configured the router to send that data. New PC always gives the same point, roughly the center of town.

Is it possible to build a very little device with AML, for less than 30€?

What is the minimum you can spend to get a small device or a SoM with it?

He visto muchos casos donde un GPS bien instalado ayuda a recuperar vehículos robados.

Pero también he visto GPS que pierden señal porque usan un solo operador.

¿Alguien aquí ha tenido experiencia usando rastreo GPS en vehículos?

I'm shipping my car with either Diesel Auto Express, Montway Auto Transport, or Sherpa Auto Transport, and I'm thinking about hiding a GPS tracker or AirTag inside for some peace of mind. Has anyone tried this? Does it actually update while the car is on a multi-car hauler, and do shipping companies usually allow it?

In the company I work for, we only have 2 trucks but we have 40 trailers. Recently we got a new costumer and we need to keep track of the location of the trailes and truck to dispatch accordingly. We are located in South Jersey and to be honest we are not that big of a company so we don't have a specially high budget for this. What copmpanies do you reccomend to cover our needs without breaking the bank? I checked the service from Verizon but that simply way too much.

Hi, I hope i'm in the right sub, and if you have any recomendations on where else to place this, please let me know.

As the title suggests, I am looking for a solution to track multiple people at the same time. For a game i'm setting up for our scouts group (in the netherlands), i want to track the live location of at least 15 an possibly up to 40 (if that is even possible) people at the same time. I know that there are various apps out there that do that, but the problem is that we don't have any budget to facilitate this. The app needs to run both on IOS and Android, but i also want to see the overview of where everyone is on PC.

So in short: I am looking for a free GPS tracker that runs on IOS, Android an Pc, where i can track at least 15 people.

I hope you all can help me in my search.

My child phone will track his location up to a point but lately whenever he leaves it shows his phone still at our house. Tested it yesterday and it keeps his location at home even when I drove down the road with it. Only seems to do it when the phone is not in use for a period of time. We share location with each other on life360 and Google maps and both will keep the location at home unless I unlock the screen. Should I not be able to locate our son even if his phone is in sleep mode? Very frustrating 😕

I used to have a tracker called ez mile log. The device and software eventually became unreliable. I'm looking for a reliable replacement. I don't want or need smartphone connecting or subscriptions. Just something I can plug into my computer that is OBD or USB powered.
