Varia connection mid activity

I never turn off (by button) my lights, ut800 and 515. They remain in the standby mode. So they start when I power on the Edge 1040.  I cannot say how it works (or not) for me in the use-case you described. I was not in the situation to turn on the lights after activity already started

For the lights control I use the Smart  Bike Lights data field. With some predefined conditions in which they should turn on, blinking and so on. 

From that data field I have the option to quickly manually override the mode selected by "smart mode" configuration. 

Thanks for the reply.

-> This seems to drain the battery.

Will have a look at the Bike Lights data field.

I consider it a very small disadvantage - I was not not in the situation to leave home and get my radar empty before ending the route - compared to the big advantage of having it turned on automatically. 

(yeah this might lead me to charging more often than others and, maybe, killing my battery faster in time)

I simply love it since I've started using it

Might be true for the RTL515, but not for the UT800. My commute takes me an hour of cycling, which means I can just reach the end with the headlight turned on all the way. When I leave the UT800 in standby (blue blinking LED) it drains the battery enough overnight so I can't get to work safely (tested it once).

Bike lights data field already installed and configured... Will test when I cycle home this evening :-)

You might be true here. I did not had the chance to test the UT800 on 1h+ rides, at night/dark conditions. My thoughts were based only on the 515 experience. 

Out of curiosity I will go check my battery on the UT800. It is in stand-by since more than 3 months

Yesterday evening turned on the light again during an activity recording, Again the light network is not being formed, which means the Bike light field also doesn't work. Only possible to set the light mode on the lights themselves.

But the second I stopped the activity, when I got home, the light network gets formed.

So this seems the be a clear bug in the Edge 1040.

After turning the bike lights back on go to the lights under sensors and toggle the light network off and then back on. It should then reconnect the lights.

The lights are not listed under sensors. Only the radar of the RTL515 is there, and that I can manually connect from the sensors menu. No way to manually connect the lights.

Is the RTL515 only paired as a radar and not as light as well?

Are you sure you don't see a "Lights" under sensors. If they are disconnected it would be the last entry in the list.
