First time query gpio status not working

Hello all
When I send an HTTP request to get a GPIO pin status for the 1st time after boot the answer is empty
It is only after setting status at least once that GPIO status request gets a valid response
Is there a reason for this?
Regards
Martin

Hello,
From what I remember this is specific to one GPIO (0?)
Have you tried the same on a different GPIO ?

Have you set 'Send Boot State' in the switch-device ?
Otherwise the state is sent first, when it has changed.

No it's no problem, as long as you don't mind it being high during a reboot.
