i have the same setup, yes you can manually turn on /off the tap. else get a servo controlled electric valve and add it to a smart socket and create a scene or remotely control with alexa/phone.
the rear end looks stamped with service , repaired and unsused ? fair amount of scratches there buddy. apologies but the price vs the description does not even match.
sorry for derailing this but 10k is too high for this given i bought this from US for 11k 5 years back. i have the same variant.
would suggest you price it reasonably.
can either of these be used to take digital out to be connected to a DAC ? as source for audio transport. basically just need the screen to play lossless media.
