When implementing my smart house, I’d really like to be able to get a call of some sort to my mobile when people press the door bell and then be able to remotely let them in and answer. Are there any support for this? Also, do you know if these are “FG approved”? I’m not sure if the “FG approval” is only a Scandinavian thing or not, but the lock needs this up here in order to be approved by the insurance companies.
