Unfortunately, in such devices, the location, to be precise, must have planetary alignment, open data, good GPS signal, and good mobile internet signal. And still, a radius of 200m... sometimes I didn't know if it was inside the house or outside... I ended up putting a camera to be able to combine...

I bought it for my father. It accurately shows where he is only when he remains stationary somewhere. When he walks, the signal can even drop out up to 500 meters
