A battery-powered tap timer with no Wi-Fi, which is exactly why it suits Home Assistant: the core integration talks to it over Bluetooth with no Gardena cloud account. The price of that is range. Home Assistant needs a Bluetooth adapter or ESPHome Bluetooth proxy within roughly 10 m of the tap, and the timer will only accept connections from adapters it has already paired with (up to 10), so swapping a dongle or adding a second proxy means re-pairing. It is a simple one-valve timer, not a multi-zone controller: if you need more than a hose-end valve, look at a wired controller instead.

This is not a controller, it is a small Wi-Fi module that plugs into a compatible Rain Bird controller you already have (or buy separately), which is the cheap way to make a conventional wired sprinkler system smart. The integration is local, which is a real advantage over the cloud-only rivals in this guide. The catches are the price (about 185 pounds inc VAT from a UK trade distributor, a lot for a module), 2.4 GHz-only Wi-Fi, and that the module handles only one request at a time, so commands can fail while someone has the Rain Bird app open.

Cheap at £22, but know what it is: Amazon UK sells the SWV-BSP as a Zigbee hose-fit irrigation timer, not a mains shutoff valve. It screws onto a garden tap (the BSP variant is the right one for UK fittings) and meters water as it goes. It is excellent for garden watering and flow reporting, and Zigbee2MQTT support is solid, but don't plumb it into your incoming supply and call it leak protection. It needs a Zigbee coordinator, and the cheap price comes with plastic build and battery power.

A Zigbee valve/pump that turns a plant monitor's readings into actual watering instead of a nag notification. We paired it with the Smart Soil Moisture Sensor Gen2 and built a moisture-tiered automation — the drier the soil, the longer the valve runs — with an explicit Home Assistant shutoff on top of the device's own timer, because a stuck-open valve is a real flooding risk you shouldn't trust to firmware alone. One gotcha worth flagging up front: it has its own onboard watering schedule that will fight a Home Assistant automation unless you set it to 0.

A £15-ish Zigbee probe that's cheap enough to put on every houseplant you'd actually be upset to lose. It pairs straight into ZHA or Zigbee2MQTT with no hub of its own required beyond a Zigbee coordinator you likely already have, and it exposes moisture and temperature as two separate entities — which is what makes it useful for automations rather than just an app widget. We used it to drive a three-times-daily watering reminder over Alexa and phone push; full build in the review.

The most capable and by far the most expensive mower in the article: £5,299 RRP at Husqvarna UK (leasing from £151 is also offered). It is a wire-free, all-wheel-drive mower for up to 5,000 m² of lawn with slope handling up to 50% at the boundary and 70% inside. Husqvarna's page says you may need an EPOS RS1 reference station, sold separately, if you lack full cellular coverage, and the Automower Connect app is required to create the virtual installation. Home Assistant sees it through Husqvarna's cloud only. Be aware of how much of its feature set the integration exposes: the docs say stay-out zones are not handled on EPOS mowers, and they do not mention NERA at all.

A boundary-wire mower for lawns up to 500 m² and slopes up to 35%, listed at £349.99 at Worx UK (reduced from £599.99, so that is a sale price, not a typical shelf price). It runs on a 20V 2.0 Ah PowerShare battery that fits Worx's other cordless tools. There is no official Home Assistant integration; the community Landroid Cloud integration (HACS) talks to Worx's cloud. Worx's page lists the ACS obstacle sensor and Off-Limits virtual fence as optional extras rather than standard, and the page heading oddly says 'Landroid S' while the contents say M500 Plus, so check the box contents when ordering.

A wire-free camera mower for lawns up to 500 m² and slopes up to 30%, at £699.99 at Worx UK (reduced from £799.99, so a promotional price). Positioning uses cloud RTK correction, which Worx says is included with no extra subscription, plus Vision AI and V-SLAM. The Home Assistant story is the weak spot: there are two community HACS integrations, and the better-known Landroid Cloud one documents Landroid Vision zones and schedules as read-only. The newer Worx Landroid Vision PLUS integration covers more, but it is a small project (10 GitHub stars at time of checking) built on a cloud API that its own README says is not public and can change without notice.

A wire-free all-wheel-drive mower for lawns up to 5,000 m², which Mammotion rates for 80% (38.6 degree) slopes, uses a built-in 4G module with a year of free 4G service, and cuts with a 400 mm dual-disc system. On 2026-11-01 Mammotion's UK page showed the 5000X variant as out of stock and was promoting the newer LUBA 3 AWD, so treat this as a model heading out of production. Home Assistant support is a community HACS integration that its own README calls a work in progress, and using your main Mammotion account in it logs you out of the phone app.

Hue's colour outdoor floodlight, and the one that makes sense if you already run a Bridge: a Zigbee light that sits on the same mesh as your indoor lamps and shows up in Home Assistant as a normal colour light. It needs the Bridge, there's no hub-free mode, and at about £148 on Amazon UK today it costs far more than the article's £89.99 figure. It's a lighting floodlight, not a security light, so there is no built-in motion sensor; pair it with Hue's outdoor motion sensor or a separate PIR in HA.

The Hue outdoor wall light to buy if you want an up-and-down fixture on a UK porch or patio wall: full white and colour, IP44, and about 1,200 lm according to retailer listings. It is a mains fitting, so it needs a proper outdoor-rated supply and a competent install, not a plug-in. The catch is the price, roughly £120-£160 per light depending on the day and the finish, which is a lot when you want a pair either side of a door. It also only reaches Home Assistant via the Hue Bridge.

Hue's low-voltage pathway bollard, a proper fixed fitting for paths and drives rather than a stake in the lawn. It runs on Zigbee through a Bridge, so Home Assistant sees it as a normal Hue colour light and control is local. Amazon UK lists the large black version as the 'Calla Outdoor Pedestal Light', which is the same Calla range. It's a base unit; extension units are sold separately and need the Hue outdoor power supply, so a long path is a real budget item. Cost per light is high compared with Govee stakes.

Mains outdoor wall light with RGB plus tunable white that joins Wi-Fi directly, and the WiZ integration is built into Home Assistant Core and runs locally. That makes it one of the cheaper ways to get a coloured porch light into HA with no bridge. The catches are common to WiZ: it is Wi-Fi only so signal strength at the front door matters, the 'Allow local communication' setting in the WiZ app must be on, and IP44 is splash-resistant rather than a fully exposed rating, so check placement. Brightness is quoted differently by different sellers (see notes), so do not bank on a figure.

At £89.99 this is £30 more than the indoor Pan/Tilt Cam Plus 3K already on this list, and the premium buys what you'd expect for a garden or driveway camera: IP66 weatherproofing rated to -20°C, a wired Ethernet option alongside Wi-Fi, and microSD support up to 512GB against the indoor model's 256GB ceiling. The headline feature, though, is the AI Event Alert system — instead of a bare 'motion detected' push notification like Reolink or Ring give you, it writes a plain-English summary ('a delivery van dropped off a parcel', 'a fox crossed the driveway at 11pm'), which is a genuine step beyond motion-only alerts. The catch: that natural-language layer runs through SwitchBot's cloud and AI Guard Premium subscription (from £3.99/mo) — RTSP streaming into Home Assistant or Frigate for local person detection is free and always available, but the clever sentence-writing isn't. Buy this over the indoor Plus 3K if the camera is actually going outside; buy the Plus 3K if it's watching a hallway and you don't need the weatherproofing.

The best battery outdoor camera for HA users who can't run cable: 4K 180° dual-lens with genuinely usable colour night vision, and the bundled 6W solar panel keeps the 5000mAh battery topped up through most UK weather (Reolink quotes 10 minutes of sun for a day's runtime, plus ~12 extra standby days over IR-only models). Unlike the mains-powered Elite WiFi and Lumus already on this list, there's no built-in siren here — two-way audio only, so lean on Home Hub automations rather than an on-camera scare-off. Battery Reolinks also need a Home Hub or NVR to appear in Home Assistant at all, so budget ~£90 extra for that; once hubbed, everything stays local.

The cheap way into UniFi Protect: a £75 wire-free 2K camera that runs off its own rechargeable battery and pulls off HA's unifiprotect integration just as well as the £300+ PoE cameras — same local streams, same instant smart-detection events. The real caveat is who this is for: existing UniFi network owners only, since you still need a Dream Machine or Protect console before it records anything. Battery life shrinks fast in busy spots — every motion event wakes it from sleep — and the modest ~6m IR range suits a porch or hallway, not a driveway. Skip it if you're starting from zero.
