Can field airtime be added to the HTTP integration?

@htdvisser
In MQTT integration, there is parameter “airtime”, but in HTTP there is not “airtime” included.
Is there possibility to get this parameter in HTTP also?

Thanks

Just in case you didn’t know: the airtime is not being measured somehow. Instead, it’s simply calculated by TTN, using the equations from Semtech’s AN1200.13 LoRa Modem Designer’s Guide.

See, e.g., implementations in:

Golang (TTN’s V2 code)
TypeScript (that’s close to JavaScript)
Google Sheets (note some hidden columns and rows)

Thanks for the info.

To get an uniform interface it would be nice that the parameter “airtime” is added to the http integration.

Did you end up calculating the airtime yourself? I’m too migrating from MQTT to HTTP integration and ran into this issue where airtime is not reported via HTTP

The only solution is to calculate it yourself, which is all TTN do - as they aren’t adding any new features to v2.

no, up to now have not found the need.
