How about something like Owntracks + Node-RED with the geofence node. Owntracks runs on your phone and can upload your location to either a MQTT broker or a HTTP server. Node-RED can either subscribe to the MQTT topic or provide the HTTP endpoints to accept the incoming messages. Then the geofence node can be set up to mark locations of interest which can ...

As detailed in my answer to the precision question (https://iot.stackexchange.com/a/341/78) the current generation of sdcards doesn't seem to support inherent geo-location capabilities anymore. Furthermore, Eye-Fi was bought by Ricoh. Looking at their product portfolio they seem to prefer to include the GPS function in the camera right away or offer ...

LoRaWAN localization uses TDOA: Time Difference Of Arrival. Gateways with the precise timing extension are all synchronized via GPS. When a device sends a frame, the very accurate time at which the frame was emitted is unknown, but by recording the exact time each of several gateways receive that frame (compared to GPS time), and knowing the position of ...

It seems to me that the last generations of the SD cards don't offer geo-tagging themselves at all. (Cf. with geo-tagging completely missing on any product specs.) The usual way nowadays seems to be to have the card automatically connect to the smartphone and use the phones location services. Thus, your tagging will be exactly as precise as your phones ...

Assuming the van as an ODB-2 port (most do) then you can just grab something like this. This assumes that you need something that reports in real-time, since you'd have to pay for a data plan. That one has an app so there must be some kind of api that it is reporting to; that system may have an open api you could leverage. Even if it doesn't, this one also ...

Firstly, how are you going to power your device? If you have a modern radio, or even a cigarette lighter USB adapter, then you can easily power an EDSP32, Raspberry Pi Zero W, BBC:Microbit, Arduino, etc. All of those could get the job done – with, in some cases, additionally Hat/Shields, so choose one that you are familiar with. I need to determine when a ...
