I built this a while back as the buzzer to my building was broken, and have been adding bits to it since! Hopefully people find it useful. I'll be adding more feaures, and already have some user suggestions in progress. You can either use it as a doorbell, or just as a way for visitors to leave a message. So far I've seen some interesting use cases including: - Home doorbells (duh) - Restricted access to buildings: "Scan the code and someone will come and get you" - Silent doorbell for sleeping babies - People who work in the back shed or garden out of earshot of their regular doorbell - Shift workers who do not want to be disturbed, but want visitors to be able to leave a message - Dog owners putting it on their front gate so that they can come and open it without pets escaping (also good for the farm gate!) Pricing wise, it's $1.50 per month to enable phone call alerts and leaving messages (gotta pay the bills). New features on the roadmap include: - Translations - Slack, Telegram, WhatsApp Alerts Let me know if you have any more suggestions :)

Congratulations on the launch!! I like the idea, it seems really cool. Although it's unlikely, I'm curious to see if you thought about misuse of the QR code? Like someone potentially having access to the QR code but they just scan/annoy the homeowner with notifications without ever actually being near the house? Just something I thought of-- regardless it's a pretty neat idea and definitely can see use of it in more single-use cases such as houseparties and other cases!

@khush_t3 Thanks! It's proved pretty practical for my own use so far. For accidental misuse, there are measures in place to stop the doorbell from ringing if the page has refreshed (ie mobile browser tab has reloaded after the visitor has left), or they scan and try and tap the ring button some time later. As far as intentional misuse goes, while we can block by trying to identify the browser/device, clearing cookies would most likely defeat that. I think that anyone with the time/energy/motivation to persistently harass someone specific will find a way to do so - be it doorbell, phone, social media, etc, until they have been dissuaded, lost interest, or found another target. The best we can do is make it inconvenient. Worst case, the user can roll their QR code and use a new one. This puts us at an advantage over the common solution of posting your phone number on the door for the delivery guy, as passers by might copy it down.
