A smart light switch buying decision starts with the exact circuit and control task. Tapo lists the UK S210 as 1-gang 1-way and the S220 as 2-gang 1-way; both specify no neutral wire and a separate H100 or H200 hub for all smart features.
For a shortlist, use the comparison below and ask your installer to confirm the actual circuit. This is a manufacturer-document comparison, with no hands-on reliability ranking or promise that either switch fits your home.

Decide what the switch must do
- Describe the circuit: tell the installer which lights you want to control and whether another wall position also operates them. Request an explicit match to the proposed model's wiring instructions.
- Name the daily action: write down on/off control, scheduled operation or brightness adjustment as separate requirements. Ask for written confirmation of each.
- Price the complete setup: request separate lines for the switch, required hub, installation and any other necessary parts. Compare total quotes, rather than the switch price alone.
Suggested decision rule: shortlist the manufacturer's one-gang type for a one-gang requirement and two-gang type for a two-gang requirement only after the installer confirms the circuit. A two-gang label alone does not establish suitability for a light operated from two locations.
Check app features with the hub included
The S220 page describes Tapo-app remote on/off control, Alexa or Google Assistant voice control, and schedules, with the stated hub requirement. These are the manufacturer's documented functions, not our measurements of response speed or service availability.
Suggested acceptance brief: ask the supplier to demonstrate your chosen app and voice action with the quoted hub and exact switch. Also ask what remains available during an internet interruption. Leave any unconfirmed answer open rather than assuming every smart switch behaves the same way.
Questions to settle before payment
Send the seller the full lamp or driver model, required switching arrangement and installer-confirmed box dimensions. Request the exact LED load limits and any dimming or multi-location support in the matching manual. Do not use an unqualified headline wattage as approval for a particular lamp group.
Keep mains wiring work with a qualified installer; this buying guide does not provide terminal connections. Use our smart-switch installation planning guide to prepare the handover, or the ceiling-light control guide if you are comparing a complete light fixture.
Frequently asked questions
Does a no neutral smart switch also mean no hub?
No. The UK S210 and S220 pages state no neutral wire is required and separately require H100 or H200 for all smart features.
Is the S220 a two-way switch?
The reviewed UK S220 page identifies it as 2-gang 1-way. Do not use the gang count as evidence of two-way circuit support; ask your installer to verify the exact arrangement.
Which is the best smart light switch for my home?
Choose from models whose circuit, required controls and total setup have been confirmed for your brief. This comparison establishes documentary requirements, not a universal winner.
