Active calories not counted

Yes the device recording the activity eg, edge should be give the responsibility for heart rate, calories ++ . It affects all Garmin watches.   Please report it to support and make a bug of it.   We are all waiting years now. Game know watch are not 100% accurate, they use the line to sell chest straps ! 

Shouldn't setting the Edge as the primary device fix the problem?

I tried that about a year ago, but it caused other problems fenix7/1040. The watch has feature that the edge does not so connect gets even more confused.  Historical they have been a series of changes the were supposed to automate this , but seems to have never worked properly.   Basicly Garimg 's continuous integration and regression testing sucks. 

Thank you, I'll try setting the watch to battery saver while using the edge and see if that fixes the problem

please note that you must turn on battery saver mode BEFORE you start activity on edge. It works brilliant and counts calories perfect.  battery saver mode settings: phone: off, wi-fi: off, wirst heart: off.... everything needs to be OFF.

Indeed this seems to work, thank you

Or maybe not...

Today I tested again switching to battery saver mode the watch before starting the activity in edge

• Before activity: 1 active calorie (I train first thing in the morning)
• Switched watch to battery saver
• Trained with edge, synced the activity: 590 active calories
• Switched off edge
• Turn battery saver off on watch, sync watch: 213 active calories

I have my watch as primary device, I will try again with the edge as primary 

Other suggestions?

I did another ride with the same procedure but with the edge device as primary training device, it didn't work either. 
Now after syncing the edge device no calories were accounted to active calories

Turning the watch completely off seems to work, even if everything was disabled in battery saver

I have an Instinct 2

Will test again tomorrow

Based on my extensive testing (Instinct 2, Edge 540, Edge as primary device):
* Edge Recording, Watch Passive: Edge's active calories are discarded, replaced by a lower watch estimate, likely due to passive mode & lack of sensor data (power meter).
* Edge Recording, Watch Battery Saver: Edge calories are added correctly until watch exits battery saver mode. Then, calories decrease significantly due to an unknown estimate (watch HR monitor inactive in battery saver).
* Edge Recording, Watch Off: Edge calories are usually added correctly, but there was one instance where no calories were added after syncing.
* Edge Recording, Watch Broadcasting HR: Improves the issue as the sensor is active. Edge calories are still discarded, but the difference is smaller (tested mainly during low-intensity commutes).
I contacted Garmin, but their only suggestion was to set the Edge as the primary training device (already done for all tests). This clearly doesn't resolve the calorie issue.
