ESP board with GNSS/Galileo and LTE/5G as a device tracker

I am looking for a board that can be easily integrated to HA with capability to use Galileo and GPS preferably and send it over cellular to my HA instance. I need about ten devices so paying a proprietary antitheft-kind solutions is not the way.

I found waveshare, which is unnecassarily big

and soracom walter which seems to be it as the company has very cheap tarifs with sims for networks around the world but they dont sell to different EU countries than France, Germany, then UK and USA

Has anybody dealt with this problem and are there some out-of-the-box cheap solutions? Thanks

Hi,

I’m the creator of the Walter module and although we are good friends with Soracom there is no SIM lock at all on Walter and you can use any IoT SIM card you like.

We are continuously working on expanding our list of distributors but already today we have worldwide availability: Walter - Multi-radio (LTE-M, NB-IoT, GPS, WiFi, Bluetooth) module with ESP32-S3

With Walter you have WiFi, BLE, LTE-M, NB-IoT and GNSS in a single, certified module. The GNSS is shared with the LTE radio to save power. This means that it is not a continuously tracking GPS because you must be in PSM mode or disconnected from cellular to do a fix. Because the GNSS is very low power it is a bit less sensitive than a dedicated module and you need to be outside for the GNSS to lock. If you are inside I would advise to use BLE or WiFi for tracking.

All info is on our website: https://www.quickspot.io and we also offer chat support via our discord channel.

For Home Assistant integration you can use MQTT.

Best regards,
Daan

Hi Daan,
thank you for your reply. Would you be so kind and provide me/us with more detailed step-by-step guide how to build it? Just some hints where to look could be fine.

My use case is to build a low power board that would track my ebike in case of theft. I will charge it by usbc from the ebike control unit and think about some small powerthrough powerbank as ups.

The easiest way for me is to build it on rapsberry pi, which I can tweak by some other sensors such as lte/gnss/vibration but the power draw is denying without buffy powerbank for which the bike frame does not provide me enough space. And finally it’s still a bike, so I do not want to make it heavier.

Any help would be appreciated! Thanks.

Hi @Vahaldor,

Sorry for the late reply. The Walter board comes pre-flashed with a tracker application that uploads data to our demo portal. This will get you started out-of-the box and it will allow you to evaluate the hardware without programming.

What I would do are these steps:

  1. Make a nice casing and find a good spot to build-in Walter on your e-bike. Make sure the GPS antenna is not obstructed by metal (under the saddle for example).
  2. Test if the reception is good and the SIM card works using the demo portal.
  3. Adapt the positioning sketch walter-arduino/examples/Positioning at main · QuickSpot/walter-arduino · GitHub and change the IP address and port to the UDP listener port and public IP of your home assistant interface.
  4. Use the node-red plugin to receive and process the messages (Receiving UDP traffic - #39 by Patryk69)

I hope this helps.

I would like to flash it with ESP Home and configure it myself. I need to attach the 18650 battery, accelerometer to detect movement, speaker for the alarm sound and CAN communicator to turn off/on the engine of the ebike. Do you provide basic documentation, so we can configure it with ESP Home and integrate it to home assistant?
