I’ve got the Withings integration installed and working for my sleep mat. It correctly creates entities for “in bed”, “deep sleep”, and “weight”, but not for 17 others, e.g heart rate, REM sleep, sleep score, and others. These values do appear in the Withings app, so I feel like they should also be picked up by the HA integration. Do any of you have these entities populated, or is this just how the integration works?
Yep Same here
For some reason, the Withings integration has these entities “disabled” by default. You need to enable them manually by clicking on the “settings” icon for a given entity and then clicking on the “Enabled” button.
How did you get the “in bed” entity? I can’t find it… 
Oh, and… the weight too?
What sensor do you have?

I have the same issue; the sensor doesn´t show up for me.
It’s been quite a while and I actually don’t remember now. But maybe this was it: go to “Settings” → “Integrations” → “Withings”, and then click on the “device” shown. You’ll see the list of sensors. If a sensor is marked “disabled” you can enable it manually there.
Doesn’t show up in mine… 
I got this device mainly for that use case…
Any luck on in_bed sensor? It’s the only one that doesn’t show up after setting up. Even after a few days.
in-bed sensor is event-driven. You have go to a bed to set in-bed state. until that its state is unknown (the same after each HA restart)
btw it’s not third party integration. It’s core built-in one
