Aqara Switches With No Neutral and Shallow UK Back Boxes

• Light Switch H2 EU: the Aqara UK Shop's 'UK exclusive version' adds an extra dark grey button, but the switch is the EU model, 85.8 × 86 × 45 mm with an in-wall depth of 30 mm, which also fits 55 × 55 mm System 55 modular frames
• Smart Wall Switch H1 EU, in No Neutral and With Neutral versions, which Aqara says suits 86 mm square wall boxes as well as round European ones
• Dimmer Switch H2 EU and Shutter Switch H2 EU, from the same H2 family

• Smart Wall Switch H1 No Neutral: designed for boxes without one; Aqara's minimum is 3 W of LED or energy-saving lamps, or 16 W of fluorescent, per channel
• Light Switch H2: works with or without a neutral. Without one it needs at least 3 W of energy-saving bulbs, 5 W of LED or 16 W of fluorescent; with one, Aqara sets no minimum
• Dimmer Switch H2: Aqara's listing gives a minimum of 4 W when it is added through Matter in Aqara Home, or 9 W by other methods, and up to 200 W of dimmable LED
• Shutter Switch H2: a neutral is required

• H1 and H2: about 30 mm inside the wall, by Aqara's figure for each
• Dimmer H2: 34.6 mm inside the wall, and Aqara's Amazon UK listing gives 40 mm as the minimum box depth
• A 16 mm or 25 mm UK box is too shallow for any of them
• A 35 mm box takes an H1 or H2; for the Dimmer H2 the pro fits a deeper box, around 47 mm

• The H2's terminals are live, neutral and switched live only, with no earth terminal
• Aqara markets the H1 with a metal frame and does not say whether it needs earthing, so on a circuit with no earth the pro fits an H2 instead
• A metal switch plate counts as Class I and needs an earth, so on an unearthed circuit the plate is all-insulated or an earth is run to it
• Aqara's H1 page shows European wire colours, so the pro identifies each conductor by testing, not by colour

• The H1 is paired with a Wireless Remote Switch H1 at the second position, which Aqara's listing says a two-way set-up requires; being wireless, it needs no cable between the two
• Aqara notes that not every twin or double wall box takes the H1, so a two-gang position is measured first
• The H1 needs an Aqara Zigbee hub to work, which is part of the set-up
• Aqara says the Dimmer H2 is not compatible with MLV (magnetic low-voltage) loads, so older low-voltage lights on a dimmer are checked

• A photo of each switch plate, and which lights it works
• The bulbs on each of those lights, so the pro can check Aqara's minimum loads
• Whether any light is switched from more than one place
• The Aqara switches you have or plan to buy, and the hub you use

A vetted pro prices your Aqara job from the models and your photos, and the JACK app shows that fixed price before you book.

What the job touches moves the price more than the device does. Pairing a hub, fixing sensors, clipping a Curtain Driver E1 onto a rail or fitting radiator thermostat heads is set-up work. A smart lock is locksmith work on the door. An H1 or H2 switch, a Dual Relay Module T2 or a 230 V blind motor is mains work on an existing circuit, priced for isolating, connecting and testing.

The home comes next: a multipoint door that needs adjusting before a lock goes on, a bell transformer too weak for the doorbell, a PoE cable through solid brick. Where a job needs a second pair of hands, your pro can ask another pro on JACK to help through the Pro2Pro feature. Several devices, Aqara or other brands, go on one booking for one fixed price.

You buy the Aqara products; JACK does not sell them. Accessories the job needs, such as a replacement cylinder, a deeper back box, a 12 V plug-in supply or a PoE injector, are agreed and added at cost before you book, and so is parking where it has to be paid for. Prefer to pay for time? As a guide, hourly hire is typically £45–£95 per hour for smart home work, £55–£110 for electrical work and £60–£130 for locksmith work, and a full-day handyman booking is a flat £350–£400 for up to 8 hours on site.
