Sifely integration
Budget-friendly hardware, portfolio-grade code management.
A Sifely lock earns its price when the codes run themselves.
Connect your Sifely account once and ProhostAI handles what the lock cannot: minting a fresh keypad code for every booking, delivering it with the check-in details, and clearing it after checkout.
Overview
Sifely is where a lot of hosts land after pricing out keyless entry: keypad, fingerprint and app entry on hardware that costs a fraction of the flagship brands. The lock does its job. The recurring work — inventing a code for Saturday’s guest, programming it, texting it, deleting it — is what eats the savings back.
ProhostAI takes that work over. Once your Sifely account is connected and each lock is assigned to a listing, every reservation gets its own keypad code with a validity window built from the stay dates: set ahead of check-in, removed after checkout. Where the lock supports it, the code is the last four digits of the guest’s phone number — something the guest knows without re-reading a message at the door.
Delivery rides your existing message flow. A template variable drops the code into scheduled check-in messages and the digital guidebook — and the guidebook can do more than display the code: for locks you enable, guests can lock and unlock right from it during the stay.
When dates move or a booking cancels, the code follows — and if a code fails to set because a lock is unreachable or its battery died, the failure is tracked and surfaced instead of silently dropped. That is the difference between a cheap lock and a cheap lock you can trust across a calendar.
What ProhostAI can do with Sifely
Once your Sifely account is connected and locks are assigned to listings, this runs on its own:
Guest access
- A fresh keypad code per booking — Each reservation gets its own code with a window built from the stay — active shortly before check-in, removed after checkout.
- Codes guests already know — Where the lock supports it, the code is the last four digits of the guest’s phone number, with a safe random fallback when those digits are unavailable or already on the lock.“Your door code is the last 4 digits of your phone number — 6640.”
- Sent with the check-in message — A template variable inserts the code into scheduled messages and the guest guidebook, so access instructions always match the lock.
Automation
- An AI employee that can work the door — When a guest asks for their code mid-stay, the AI can look it up, generate a fresh one, or unlock the door on request — audited, rate-limited, and never for cancelled or past bookings.
- Codes follow the calendar — Date changes move the code’s window while the digits stay the same — the code the guest already received keeps working. Cancellations remove the code entirely.
- Failures get surfaced, not swallowed — Code-setting is driven through to confirmation. An offline lock or dead battery becomes a tracked, visible problem you can fix before arrival.
- A history per lock — Unlocks, code changes and failures land in a per-device timeline you can actually check when something seems off.
How to connect Sifely
Connecting Sifely takes a few minutes and happens entirely in the browser:
- 1In ProhostAI, open Smart Devices and choose Connect account.
- 2Pick Sifely in the secure connection window and sign in with your Sifely account credentials.
- 3Your locks sync in automatically with battery and connection status.
- 4Assign each lock to its listing and name it the way guests would (Front door, Side entrance).
- 5From the next reservation on, codes are created, delivered and removed automatically.
Good to know
Sifely locks offer keypad, fingerprint and app entry — ProhostAI manages the keypad codes, which is the entry method your guests actually use.
For remote code management the lock needs to be reachable from your Sifely account — Sifely’s WiFi gateway is how most hosts keep locks online.
ProhostAI only manages the reservation codes it creates; your own owner and cleaner codes stay on the lock untouched.
Connected devices are a paid add-on billed per device, and the connection never exposes your Sifely password to ProhostAI.
