can I get my Sleep and HRV from Withings into intervals ?
Will it share with google fit and then to intervals?
I understand integration with between Withings and Google Fit has been withdrawn.
Oh that would explain why my BP doesn’t sync. But its still listed as an option under connections… strange…
As long as it’s hosted on a server and not on your phone, and it’s accessible to you, it’s possible to retrieve it manually and sync it to intervals via the REST api.
The Withings data is held in the cloud so it should be accessible, ideally I wuld looking for someone who has already done this
No that doesn’t seem to be the case.
Just now I recorded my BP and it went into Fit.
I connected both withings and Fit to health connect and gave them both permission to read and write everything. The withings app/BP monitor side of it is pretty stupid IMO and took a lot of fiddling to make the jolly thing even write to the app, but once it did it appeared almost immediately in Fit. But I haven’t seen it come through on intervals 
It looks like fitness syncer can’t read HRV
Maybe contact them and ask why it doesn’t appear in the list of possible metrics ??
Anyway, I got the silly thing working for BP via fitness syncer, so I guess that’s a win for me.
BreakAway supports Withings sync
HRV is only available for Enterprise API Plans and then seems like there’s a diff in availability between US and EU sites:
Apparently there is a public API for withings, so you could grab the data from there and push it to intervals. You might be able to use IFTTT to trigger google sheets to download and upload the data. Or if you don’t need it to be instantaneous, have a google script that runs at 10 am or something.
But it seems that app4g’s info about biomarker packs stymies that idea!
