Ajax Home Automation: Local Security, 2,000m Range, Epicloud Install
Ajax home automation is a security-first wireless system that also runs automation scenarios for lighting, sockets, heating and rapid water shut-off. It suits homes that need long sensor range, reliable detection and compatibility with professional monitoring rather than a convenience-only smart home gadget. For supply and setup, we handle Ajax installation and configuration as certified specialists.
TL;DR:
Scenarios run locally on the hub, so leak shutoffs and scheduled lighting still work during broadband and mobile outages at the property.
Pair LeaksProtect with WaterStop on the mains feed to a washing machine or dishwasher; the valve closes in about seven seconds after detection.
Jeweller radio reaches around 2,000 metres in open space; Hub 2 Plus adds Ethernet, dual SIM backup, and about 15 hours of battery runtime.
If three or more rooms lack a neutral wire, choose certified installation; several LightSwitch models do not require one at the switch.
UK professional monitoring through a Central Monitoring Station typically costs £15 to £30 per month, depending on the selected service level.

What Ajax automation covers: comfort, safety and leak prevention
Ajax’s Comfort and automation range covers wireless devices for everyday convenience and for emergencies alike: switches, sockets, relays and shut-off valves that all report back to the same hub as the security sensors. That shared backbone is what separates Ajax from gadgets bought one at a time from different brands.
Automation runs on what Ajax calls Automation Scenarios, which trigger a device or group of devices in response to an event rather than needing a person to press a button every time.
An alarm event can switch off mains power or close a valve automatically.
A schedule can turn heating or lighting on and off at set times.
Arming or disarming the system can trigger a “welcome home” or “away” routine.
A temperature, humidity or CO2 reading can switch on ventilation or heating.
A single button press can run several actions at once.
The leak prevention use case shows the logic clearly: a LeaksProtect sensor detects water, and WaterStop closes the valve in about seven seconds, stopping a burst pipe before it floods a kitchen or bathroom.
Key automation devices and what each does
A handful of devices cover most automation needs, and each solves a different practical problem.
WallSwitch: a wireless relay rated for loads up to 3 kilowatts with live energy monitoring in the app, useful for heating, pumps, lighting circuits or powering a third-party camera only when a scenario calls for it.
Relay Jeweller: a dry-contact relay for locks, valves and other third-party equipment, with pulse or bistable modes so it can momentarily trigger a gate motor or hold a circuit open until told otherwise.
LightSwitch: a touch panel available in one-gang and two-way configurations; several LightSwitch models work without a neutral wire, which matters in older UK properties where retrofitting a neutral to every switch plate is impractical.
WaterStop and LeaksProtect: paired together, the leak sensor detects moisture and the valve shuts within seconds, with no reliance on anyone being home to react.
Button and KeyPad: physical triggers for scenes that do not need a phone, such as a bedside button that arms the system and turns off every light at once.
Pro Tip: Fit WaterStop on the mains feed to a washing machine or dishwasher first. These appliances cause a disproportionate share of domestic water damage, and a single valve there covers the highest-risk point in the house.
How Ajax automation works: Jeweller protocol and hub redundancy
Automation is only as dependable as the radio link carrying the commands. Ajax devices communicate over Jeweller, an encrypted two-way radio protocol built for alarm-grade reliability rather than general-purpose smart home convenience.
Jeweller’s quoted open-space range reaches around 2,000 metres, far beyond what Wi-Fi-dependent consumer alarms typically manage, which is why Ajax sensors keep reporting reliably from outbuildings, garages or large gardens.
The hub side adds further resilience. The Hub 2 Plus connects through four independent channels: Ethernet, Wi-Fi and dual-SIM 4G/3G/2G, backed by roughly 15 hours of battery runtime. Automation scenarios execute locally on the hub itself, so a lighting schedule or a leak shut-off still runs even if broadband and mobile signal both fail at once.
Integration options and third-party compatibility
Ajax covers security and core automation natively, but readers often want to know how far it stretches into wider smart home setups.
Community-built integrations for Home Assistant exist and are actively developed, though they can need add-ons or translator modules and vary in stability compared with Ajax’s own app.
Third-party cameras are not natively controlled by Ajax, but a WallSwitch or Relay can power a camera only during an armed or alarm state, which is a practical workaround rather than a direct integration.
Direct connection to a Central Monitoring Station (CMS) lets a professional monitoring company watch for alarms around the clock, with UK monitoring typically priced around £15 to £30 a month depending on service level.
For anyone who wants native voice assistant control as a daily habit, it is worth treating Ajax as a security platform with useful automation extras, rather than expecting it to behave like a general-purpose smart home hub.
How to plan an Ajax automation install: a budget checklist
A short planning exercise avoids ordering the wrong hub or discovering a wiring problem after the sensors are already on the wall.
Map each room or zone you want covered and note distances to the planned hub location.
Check mains wiring at switch plates and sockets, including whether a neutral wire is present.
Decide whether you need dual-SIM connectivity as backup to home broadband.
List which devices you need: switches, relays, leak sensors, WaterStop valves, buttons.
Budget separately for hardware, any installer time and ongoing CMS monitoring fees.
Starter kits cover the core hub and sensors, while WallSwitch, Relay and WaterStop units are added individually based on the checklist above.
Pro Tip: If more than two rooms lack a neutral wire at the switch, or you need valves plumbed into mains water, that is usually the point where hiring a certified installer saves more in rework than it costs.
Epicloud: supply, install and support for Ajax automation
We supply, configure and install Ajax systems, including starter kits sized for different property layouts. A typical installation includes a site survey to confirm sensor placement and wiring, physical fitting of hubs and devices, programming of the automation scenarios covered above, and handover to CMS monitoring where a customer wants professional monitoring in place from day one.
When automation should be security-led, not convenience-led
Automation tied to alarms, schedules and sensor thresholds, running locally on the hub, keeps working when broadband drops or a cloud service has an outage. That matters for a leak shut-off or a door lock far more than it matters for a mood-lighting scene. Treat cloud-only integrations and voice assistants as a layer on top of core security actions, never the thing those actions depend on.

How Epicloud can help: starter kits and installation booking
We make it straightforward to go from reading about Ajax to having it working on your walls. If you would rather not plan sensor placement and wiring yourself, our Ajax certified installation service covers the site survey, fitting and scenario programming described above, with a quote provided after the survey.
If you prefer to buy and fit hardware yourself, our KIT1 2G+LAN starter kit suits a flat or small house, while the KIT5 starter kit gives larger properties more devices out of the box. Either way, a short survey call is the fastest way to confirm what your home actually needs.
FAQ
Is Ajax better than Ring for home automation?
Ajax is built as a professional-grade, security-first system with long-range Jeweller radio and CMS monitoring compatibility, while Ring is primarily a consumer video doorbell and camera ecosystem. Which one suits you depends on whether you prioritise alarm-grade detection and professional monitoring or video-first convenience features.
What is the best home automation system for a security-focused home?
For a security-focused home, a system built around encrypted, long-range sensors and local scenario execution, such as Ajax’s Jeweller-based platform, tends to suit better than Wi-Fi-only consumer kits. The right choice still depends on property size, wiring and whether professional monitoring matters to you.
What security system do burglars dislike most?
Burglars tend to avoid homes with visible, responsive alarm systems backed by audible sirens and fast professional monitoring, since quick detection reduces the time available to act. A system with long sensor range and reliable connectivity across the whole property closes gaps that a patchy Wi-Fi-only setup can leave open.
How much does an Ajax security system cost?
Ajax hardware is sold in starter kits plus additional devices such as switches, relays and leak sensors added to suit the property, with installation available through our professional Ajax installation service and pricing confirmed after a site survey. Ongoing professional monitoring through a CMS in the UK typically runs around £15 to £30 a month.
