Weirldy yesterday I was looking at an app called #networksurvey that I use from #fdroid and it includes the capacity to updload survey data to #opencellid and #beacondb - both of which I know nothing about but which I think are relevant to your query.
Well its time to say goodbye to our corner #sofa - its from #IKEA and you can buy new covers if you don't like the colour - and it free to a good home - If you are in the #London area we might even be able to deliver it
