Why did my NERO Environexus smart home stop working?

Environexus ceased operations in December 2024 and the NERO cloud servers went offline. The NERO app, remote access and cloud-based automations all depended on those servers, so they stopped working — even though the switches in your walls are still perfectly good hardware.

Can my existing NERO switches and dimmers be saved?

Often, yes. NERO devices are standard Australian-frequency Z-Wave hardware, and many can be re-paired to a new, locally hosted controller. We audit each device: what can be re-paired is kept, and anything failed or incompatible is replaced like-for-like with current smart hardware.

Will my smart home get shut down again after the upgrade?

That is exactly what we design against. We rebuild NERO systems around a controller that runs locally in your home — day-to-day control does not depend on any company's cloud staying online. You then use it through Apple Home or Google Home, the two most widely supported smart home platforms in the world.

Should I choose Apple Home or Google Home to replace NERO?

Either works. Households on iPhone usually prefer Apple Home for its interface and Siri, Apple Watch and iPad integration. Mixed or Android households often choose Google Home. We set up whichever suits your family — the underlying system is the same.

What does a NERO replacement cost?

It depends on how many devices you have and how many can be re-paired versus replaced, so we quote after an on-site audit of your system. You receive a fixed, written quote before any work begins. We service all of Greater Sydney.

Servers offline NERO by Environexus

NERO's servers are gone.
Your smart home doesn't have to be.

Environexus ceased operations in December 2024 and took the NERO cloud with it. We rescue NERO homes: failed switches replaced, the rest re-paired, and everything rebuilt on Apple Home or Google Home — with local control that no company can switch off.

Quick answer

Why did my NERO smart home stop working? Environexus, the Australian company behind NERO, ceased operations in December 2024 and its cloud servers went offline. The NERO app, remote access and cloud automations all depended on those servers. The switches in your walls are still good hardware — NERO used standard Australian-frequency Z-Wave. Cync Electrical re-pairs what can be saved, replaces what can't, and rebuilds your system on Apple Home or Google Home with local control, so it can never be shut down remotely again.

The short version

What actually happened to NERO

2016 – 2023

Sold through the trade

NERO was an Australian-designed Z-Wave platform sold through major electrical wholesalers, and it went into thousands of homes — dimmers, relays, plug packs, sensors and security, all run from a NERO hub and cloud account.

Dec 2024

Environexus ceases operations

The company behind NERO closed down. Its cloud servers — the ones the hub, app and remote access relied on — went dark, and support went with them.

Today

Good hardware, no brain

The Z-Wave modules in your walls still switch and dim perfectly. What's missing is a controller and an app with a future. That's the part we replace.

What we do

Rescue first. Replace only what's needed.

Most NERO rescues keep the majority of your existing switches. You pay to fix the system, not to start again.

Audit every device

We test each switch, dimmer and sensor at the wall and on the network. You get a clear list: what's healthy, what's failed, and what won't carry across.

Replace the failures, keep the rest

Dead or incompatible switches are swapped like-for-like with current smart hardware. Healthy NERO modules are re-paired to a new controller that runs locally in your home.

Rebuild in Apple or Google Home

Rooms, scenes, schedules and voice control come back — in the Apple Home or Google Home app your family already knows. Remote access included, no NERO account required ever again.

🔒

Built so this can't happen to you twice

NERO died because everything ran through one company's cloud. Your rebuilt system is different: the controller lives in your home and works even with the internet down, and you use it through Apple Home or Google Home — the two most widely supported smart home platforms on earth. No single small company between you and your light switches, ever again.

Questions from NERO owners

Can my existing NERO switches be saved?

Often, yes. NERO devices are standard Australian-frequency Z-Wave hardware, and many re-pair cleanly to a new locally hosted controller. Some carry across with reduced features and some don't carry across at all — that's exactly what the audit tells you before you spend anything on replacements.

Will this happen again with the new system?

This is the question that matters, and it's what we design against. Day-to-day control runs on a controller inside your home — it doesn't need any company's server to switch a light. The interface is Apple Home or Google Home, platforms with billions of devices behind them. That's a fundamentally different risk profile to a single-vendor cloud.

Apple Home or Google Home — which should I pick?

iPhone households usually prefer Apple Home: the interface is superb and it ties into Siri, Apple Watch and iPad. Mixed or Android households usually pick Google Home. The system underneath is the same either way, and we'll set up whichever suits your family.

Do you need my old NERO login or hub?

No. The NERO cloud is gone, so there's nothing to log into. We work directly with the devices in your walls — excluding, re-pairing and testing each one on site.

What does a NERO rescue cost?

It depends on device count and how many re-pair versus need replacing, so we quote after an on-site audit. You get a fixed, written quote before any work begins — and because we rescue rather than rip out, it's usually a fraction of a full reinstall.
