Connect your Paradox alarm panel to Home Assistant — with Home Assistant
running right on the device. No separate hub required, no cloud, no
monthly fees.
Once-off purchase · No debit orders · No ongoing costs
The LocknAlert Bridge V2 connects directly to your Paradox alarm
panel's built-in serial port — and it runs Home Assistant on the
device itself, the same platform that powers our Home Hub and Home
Hub Secure+. You don't need a separate Home Assistant instance or
hub: plug in the Bridge V2 and your alarm is a full smart home
controller.

often before you'd need to call your installer
Fully local — nothing leaves your home network
Works during load-shedding and internet outages

Why LocknAlert Bridge V2?
Everything the original Bridge does — plus Home Assistant built right
in.
Home Assistant on-device
No separate hub, no external instance to maintain. The Bridge V2
is a full Home Assistant appliance for your alarm.
R0 / month forever
One purchase. No debit orders, subscriptions, or hidden costs —
ever.
Works offline
Keeps working during load-shedding and ISP outages. Local is
always reliable.
Stays in your home
Runs on your local network. No third-party servers involved at any
point.
Guest & Service Access, Built In
Give an Airbnb guest, your cleaner, or the gardener their own way in —
without ever sharing your alarm code.
A code for every guest
Date-range codes for Airbnb stays, one-time codes for a service
visit, or permanent codes for a regular cleaner or gardener — each
one separate from your own.
No app for your guest
Codes are sent straight to WhatsApp with a link to a
phone-friendly keypad. They tap the link, type their code, they're
in — nothing to download or install.
Home Assistant knows who came by
Every code fires its own Home Assistant event — "guest arrived",
"gardener disarmed" — so you can build automations: lights on, a
notification, whatever you want.
AI-powered diagnostics
LocknAlert's built-in AI assistant, Locki, explains problems in
plain English and suggests a fix — right on the dashboard or over
WhatsApp — often before you'd need to call anyone.
