Thanks, I’ll have a look and see what I can find.
Balderdash. Maybe if your house is built of fibreglass. My current house has a galvanised iron roof and insulating foil in the walls. Dispute having huge bay windows GPS does not work inside. I have not once found a house that a GPS works inside of and I’ve lived in a lot of places.
Do you think I’m making it up? What would be the point? Stop waffling about how it can’t be, when I’m showing you it can. You’re not helping or contributing to the discussion in any way.
Tin roof and foil walls are left for sheds here, we have concrete tiles on wooden sarking and cavity brick walls. GPS has worked in my last 3 houses in 2 countries. Both phone GPS and Garmin.
Brick | Air Gap | Foil | Plywood | Fibreglass insulation bats | Gyprock is not an ancient building technique.
Even tiled roofs should have foil backing for heat reflection, unless your house was built in the 1800s.
Indoor GPS?
No https://space.stackexchange.com/questions/35235/what-is-required-to-make-gps-signals-available-indoors
No https://www.gps-repeaters.com/blog/why-doesnt-gps-work-indoors/
For the vast majority of people GPS does not work indoors and falls back to cell tower triangulation.
I specifically have one of these in my workshop for testing field equipment at my day job: Repeater Kits - GPS/Cellular - Rojone Pty Ltd - Australia
I genuinely don’t care Tom, I have GPS anywhere in my house and have in 2 previous. There’s the bedroom, under the roof Gable end, behind a metal horizontal window blind. As you can see, accuracy takes a slight hit but only up towards 10m. I can work out what quadrant of my house I’m in from GPS only. This works in my phone, in my garmin etrex, and I’ve just checked my drone GPS module is a bit worse but never locks me outside the garden boundaries (20m accuracy).
“No” is a stupid response and I expect better of moderators.
No, assuming your situation is applicable to everyone else is the stupid response.
I guess I don’t understand the problem. If the GPS works perfectly inside then why is your position being reported erratically?
I think there may be a couple things going on.
a) part of the GPS information is accuracy. The companion app AFAIK does not let you filter out GPS data that has poor accuracy. This is one of the reasons I used owntracks instead, you can configure on the phone or in HA the minimal accuracy required to use the GPS position. Initially I set this to 200m and recently changed it to 1000m. As 200m was filtering out too many positions when I’m driving and my phone is in the back pocket. What I plan on doing is implementing adjustable accuracy based on zone, e.g. when I’m around home have it be 100m and when more than a couple miles away increase it. The owntracks integrations logs warnings whenever the GPS accuracy is not met - which is helpful for understanding what’s going on.
b) speculation. I believe there is a difference in GPS accuracy when running the chipset in “always on / map tracking mode” vs “battery friendly / not always on mode”. For example, when I turn my Garmin running watch on inside or when it’s super cloudy outside - it can take a minute or two (sometimes) for it to lock position and start tracking. There is a bunch of GPS timing information that has to be received from the satellites. So I speculate when in “battery saving mode”, it may not wait fully for a lock. Whereas in your test the chipset is fired up, staying on and keeping a lock (and burning battery)
