I am about to purchase the nest doorbell from here https://www.amazon.de/-/en/Google-Nest-Doorbell-Battery-Operated-Function/dp/B09TNPTM8Q/ref=cm_cr_ar...
My only concern is the height of the existing wiring is not 4 feet as recommended but higher at 5feet....would this be too high or would i be ok do you think?
Yes, Google Nest recommends 4 feet. If you need to mount it at 5 feet, you could perhaps look at a vertical wedge or mount, like these on Amazon, to tilt the doorbell down slightly:
It looks like we can consider this one complete, so I will be locking this in 24 hours if we won't hear back from you again. Feel free to start a new thread and we'll be happy to help.
