I think the best use case I’ve seen for nfc tags are periodic reminder reset. Place a nfc tag near your filter register then when you change your hvac filter, scanning the tag records the date which can then be used to send notifications when it’s time to change the filters again.
Hello. Can anyone recommend a smart button that I could use as a connected doorbell? We already have camera coverage on the front porch so no need for video doorbell. Would prefer zwave but am open to zigbee as well. Our front porch is covered but am concerned about using an indoor button outside, mostly because of temps, esp in winter.
