Quick answer: Yes, you can do a lot. Plug-in plus mount-free plus battery-powered plus a portable hub on the shelf. Total kit runs $500-$1,500 and is 100% reversible — no drilling, no electrician, no landlord approval needed for any of it. Everything in this article you take with you when the lease ends.
What Works Without Drilling Holes
The smart home stack splits into "needs an electrician" and "runs off a power point". For renters, the second category has grown fast — Matter-over-Wi-Fi, Zigbee 3.0 battery sensors, and portable hubs mean you can run a useful smart home without touching a wall. What works in a rental with zero property modifications:
- Smart plugs. TP-Link Tapo P110 or Aqara SP02 Zigbee plugs, $20-$40 each. Any plug-in appliance becomes schedulable, monitorable, automatable. Appliance-level energy data is a free side effect.
- Battery-powered sensors. Aqara contact sensors, Sonoff Snzb-02 temp/humidity, Aqara motion, Aqara water leak — coin cells, 3M tape, Zigbee to the hub.
- Screw-in smart bulbs. Philips Hue, Aqara LED, Sengled or Ikea Tradfri into any B22 bayonet or E27 socket. Original bulb in a drawer, smart one in your hand on move-out. $15-$60 per bulb.
- Smart speakers and displays. Apple HomePod mini, Google Nest Hub, Amazon Echo. Plug-in, portable, voice control, and (HomePod and Echo) Matter + Thread border routers.
- A Matter hub on existing Wi-Fi. Aqara M3, Apple TV 4K, HomePod mini, or Home Assistant Green on a shelf next to the modem.
- Removable mounts. 3M Command strips and hooks hold indoor cameras, displays and motion sensors. Tested across painted plasterboard, tile and timber — none pulled paint when removed correctly.
- Wireless cameras on countertops. Tapo C220, Eufy Indoor Cam, Aqara G3 sit on a shelf and run from USB-C. Battery + solar outdoor units (Eufy SoloCam S40, Reolink Argus) clip to balcony railings.
- Retrofit door and window sensors. Aqara T1 contact sensors — paper-thin, magnetic, 3M-stuck, open/closed in real time. We use these on garage doors, sliding glass doors, mail slots.
What WON'T Work in a Rental
Before the recommended kit, what you have to skip. We've had renters call us after buying $2,000 of Shelly relays and Aqara wall switches assuming they could hide them behind faceplates and the landlord would never know. They spent the money for nothing. What stays in the box:
- Hardwired in-wall switches. Aqara H1 wall switches, Sonoff Mini relays behind existing GPOs, Shelly 1PM relays in the ceiling rose — anything inside the wiring is off-limits. It's also a licensing issue: only a licensed electrician can legally do that work in NSW.
- In-wall keypads and screens. Flush-mount touch panels need a back box and a Cat6 run. Not happening in a rental.
- Cat6 cabling to a hub. Pulling cable through ceiling cavities alters the building's infrastructure. Wi-Fi 6 covers everything in our recommended kit.
- Anything needing a sub-panel. Whole-home energy clamps (Shelly EM, IotaWatt, Emporia Vue) need an electrician. Renter-friendly alternative further down.
- Smart locks that replace cylinders. Most landlords will say no to a Yale Linus or Aqara U200 because changing the cylinder impacts key access. Retrofit thumb-turn locks (which sit over the existing deadbolt) are usually tenant-friendly — ask before installing.
- Permanent ceiling-mounted cameras. POE cameras with fixed plates need a drilled mount and Cat6. Battery and Wi-Fi cameras on shelves are the substitute.
Rule of thumb: if it goes behind the surface or needs a sparkie, skip it. If it plugs in or runs on a battery, you're fine.
The Setup We Recommend for Renters
We've done enough rental-friendly setups across Erina, Gosford and Terrigal to have a default kit. Pick a hub, add a common device list under it:
Pick One: Your Hub
Best all-rounder. Built-in Zigbee 3.0, Thread border router, Matter controller, IR blaster (for the air-con remote). Works with Apple Home, Google Home, Alexa. Plugs into the wall, sits on the modem shelf. Local automations run without internet. Our default.
If you already live in Apple, HomePod mini is a Thread border router, Matter controller and a speaker. Catch: Matter and Thread only, no Zigbee — you can't directly run Aqara or Sonoff sensors without an additional Zigbee bridge.
For renters who want proper Home Assistant without building a Raspberry Pi. Pre-installed, sits on a shelf, runs locally. Steeper curve, infinitely more configurable. DIY enthusiasts gravitate here once they outgrow the Aqara app.
If you've already got one, it's a Thread border router and Matter controller out of the box. Same Matter-only limitation as HomePod mini. Good if you own one; not worth buying just for the smart home role.
The Common Kit (Whichever Hub You Pick)
- 4-6 smart plugs. TP-Link Tapo P110 for Wi-Fi ($20-$25) or Aqara SP02 for Zigbee ($30-$40). One on the TV, one on the bedside lamp, one on the heater, one on whatever else. Tapo P110's energy data pairs nicely with our energy monitoring guide.
- 2-4 smart bulbs. Philips Hue White ($25-$35) or Aqara LED for key fixtures — bedside lamp, the hallway bulb you can't reach, the lounge ceiling rose. Don't bulk-buy 20 bulbs; pick the ones that need automation.
- 3-5 battery sensors. Motion sensor in the hallway, contact sensor on the front door, water leak sensor under the kitchen sink, temperature sensor in the bedroom. Aqara MS T2 motion and Sonoff Snzb-02 temp/humidity are our defaults. $20-$30 each.
- Optional: Aqara FP2 mmWave occupancy sensor ($129). Presence detection rather than motion ("lights stay on while I'm sitting still reading"). Mains-powered via USB-C, plug-in only.
- Optional: 1-2 indoor cameras. Tapo C220 ($59) or Aqara G3 ($129) on a bookshelf, pointed at the front door or living room. Slots into our security setup without drilling.
All in: hub $150-$250, plugs $120-$240, bulbs $50-$200, sensors $100-$200, optional camera and FP2 $200-$300 — the $500-$1,500 indicative range. Add $200-$400 for a portable 4G/5G modem if you don't want to depend on the landlord's NBN.
Matter-over-Thread is worth a mention. Newer Matter devices (Aqara P2, Eve Energy) use Thread mesh, and most Apple and Google devices act as Thread border routers for free. Downside: Matter is younger, device range narrower, pairing still flakey at times.
What You Take With You When You Move
We tell every renter on a first call: this kit is portable infrastructure, not a renovation. When the lease ends, here's the un-install order:
- Smart bulbs. Swap originals back in. Smart bulbs into a labelled ziplock. 5 minutes per fixture.
- Battery sensors. Peel off 3M tape (hairdryer on warm if it's been on more than 18 months). All in a shoebox. 10 minutes total.
- Smart plugs and cameras. Unplug. Box up.
- Hub. Unplug from wall and modem.
- 3M Command strips. Pull the tab straight down — stretches and releases clean. Yank and paint comes off. Pull slowly.
Total move-out on a fully kitted 2BR apartment: about 20 minutes of physical work, plus an hour to back up the hub config. What stays at the property: nothing. Not a hole, not a wire, not a screw.
The one thing renters forget: back up the hub config before you unplug. Aqara has a cloud backup; Home Assistant exports a one-click .tar. Restore on the new property and your automations come back without re-pairing. We've seen renters lose 40 hours of work skipping this step.
When DIY Hits Its Limit — and What We Charge to Clean It Up
We get a lot of calls that start "I've been doing this myself for two years and it's broken." The common breakdowns:
- Zigbee mesh weakness in apartments. Zigbee mesh routes through powered devices (plugs, in-wall switches). With battery sensors at the far end and no plugs in between, devices drop offline intermittently. Fix is usually adding one or two Aqara plugs as Zigbee repeaters — but finding the dead zone takes signal analysis.
- Hub conflicts. HomePod mini thinks it owns the Aqara devices. Google Home thinks it owns the Hue lights. Home Assistant tries to control everything and gets overridden. Multi-hub setups need a clear hierarchy — one local controller as source of truth, the rest as voice front-ends only.
- Automations that break when guests change the Wi-Fi password. Wi-Fi-only plugs and cameras drop and need re-pairing; Zigbee and Thread devices keep working. This is why we push renters towards Zigbee and Thread wherever possible.
- The Aqara-Home Assistant tug-of-war. Pairing the same sensor into both apps creates race conditions where neither has authoritative state. Pick one as primary; expose to the other read-only.
- Old YAML automations that don't match new device IDs. Home Assistant device renames or re-adds break every automation referencing the old entity_id. Constant problem when DIYers reset a hub and re-pair without exporting first.
For DIY enthusiasts who've hit the wall, we run "fix my Home Assistant mess" passes — audit, fix mesh and hub issues, rebuild broken automations, document. $1,000-$5,000 depending on rabbit-hole depth. You can book a free 30-minute phone consult first. We also handle dashboard rebuilds and design automation logic from scratch for a clean restart.
Special Notes: Share Houses, Apartments, and Unit Blocks
The setup for a 2BR Erina apartment is not the setup for a 4-share student house in Wyong:
2-bedroom apartment, single tenant or couple: The kit above works out of the box. Mesh is fine because the space is small. One hub, six plugs, four sensors, two bulbs. Landlord's NBN is usually sufficient. DIY install: 4-6 hours.
4-bedroom share house: Wi-Fi is the biggest issue. If the housemate paying for NBN moves out, the smart home dies. Run your own portable 4G/5G modem, or put everything on a guest SSID. Flip the SSID name in the hub when the lease churns and you're done.
Unit blocks with shared walls: 2.4 GHz Wi-Fi congestion is real. In one Gosford block we counted 23 visible 2.4 GHz networks from a single unit. Wi-Fi plugs and cameras become unreliable. Zigbee tolerates congestion better — weight buying decisions towards Zigbee or Thread over Wi-Fi.
Battery life: CR2032 Zigbee sensors run 18 months to 3 years. Frequent-reporting (motion, presence) die fastest; contact and temperature last longest. Budget $5/year per sensor in coin cells.
For renters across the Central Coast — Erina, Gosford, Terrigal, Woy Woy — we offer phone consults rather than full site visits for the no-drill setup. Renters in Terrigal and Woy Woy have been our biggest cohort: beach apartments, units behind a main house, weekenders.
The Limit of No-Drill
Straight up: a fully kitted renter smart home is roughly 70% of a fully kitted owned home. You get automation, monitoring, voice control, notifications. What you don't get: in-wall switching (guests flip the wall switch and cut power to your smart bulbs), permanent outdoor cameras, and whole-home energy clamps. For most renters, 70% is exactly what they need. The other 30% you build out the day you sign a mortgage — and the hub and Zigbee devices come with you. Nothing wasted.
Frequently Asked Questions
Do I need to tell my landlord I'm installing a smart home?
For the no-drill kit described in this article — smart plugs, battery sensors, screw-in smart bulbs, a portable hub on a shelf — no, you don't. Nothing is being modified on the property. We tell renters to treat it like installing a new TV: it's your gear, it goes with you. The only items that genuinely need landlord approval are anything hardwired (in-wall switches, Cat6 runs, switchboard energy clamps) or a lock cylinder replacement.
What about strata in an apartment block?
Strata by-laws govern shared property — exterior walls, common areas, the building's electrical and network infrastructure. Plug-in devices, battery sensors and a hub inside your unit are not strata's business. Where strata does come in: any camera with a view of the corridor or another unit, anything attached to a balcony rail or external wall, and anything that needs to be run through ceiling cavities to neighbouring units. Keep cameras pointed inside your own unit and you'll have no issues.
What if I move interstate — does the kit still work?
Yes, with one caveat. The hub, sensors, plugs and bulbs all migrate fine. The Aqara M3 and HomePod mini both use 2.4 GHz Wi-Fi, which is universal. The caveat: your automations may reference the old property's layout (e.g. "turn on hallway lamp when front door opens"). You'll need to re-map device locations in the app when you move — about 30 minutes of work, not a re-purchase.
Are smart bulbs worth it in a rental?
For fixtures with a standard B22 bayonet or E27 screw-in socket, absolutely — they replace the original bulb in 30 seconds and the original goes in a drawer until you move out. The Philips Hue and Aqara LED bulbs work well over Zigbee. Where they're not worth it: pendant lights you can't reach without a ladder, downlights that use proprietary fittings, and any fixture where the wall switch is regularly cut, since the bulb loses power when the switch is off.
Do battery sensors die quickly?
In our experience, no — battery life on most Zigbee sensors is 18 months to 3 years on a CR2032 coin cell. The Aqara contact sensors and Sonoff Snzb-02 temperature sensors we deploy regularly last 2 years before the low-battery alert fires. The Aqara FP2 mmWave occupancy sensor is the exception — it's mains powered (USB-C), so it needs a power outlet nearby.
Can I get monitoring without using the property's NBN?
Yes. A 4G/5G mobile router (Telstra, Optus or aussie Broadband all sell portable units around $200-$400) gives you a private network that the smart home runs on, completely independent of the landlord's NBN. Useful in share houses where the housemate controlling the modem is unreliable, or in granny flats where the main house Wi-Fi doesn't reach. Data usage for a typical smart home setup is minimal — under 2GB/month.
Can the Aqara hub work without internet?
Mostly yes. Local automations — "motion sensor turns on the lamp", "door opens, hallway light comes on" — run on the hub itself and continue working with no internet at all. What stops working: remote app control when you're away from home, voice assistants (Google/Alexa/Siri), and any cloud-based automations like weather-triggered routines. For renters who want a fully local setup we typically recommend Home Assistant Green over the Aqara hub, since HA does local-first by design.
Stuck on which hub to buy, or how to fix what you've already built?
We offer free 30-minute phone consults for renters across the Central Coast. No site visit, no pressure — just a conversation about what you've got, what you want, and the cheapest path to get there.
