Aqara H2 vs Z1 Pro: Which Wall Switch Fits Your Malaysian Wall Box?

Answer up front — "Aqara Wall Switch H2" is not a single product. It is a per-market family, and "H2 Pro" does not exist: the name returns zero results across all 1,440 product URLs on Aqara's own site, and direct probes of the expected pages return 404. Only two H2 variants publish readable text specifications, and both are US parts rated 120 VAC against a Malaysian 240 V supply, so voltage, certification and back-box fit must be confirmed before anything is ordered. The "Z1 Pro" is really the Smart Wall Switch Z1 Pro SEA, whose specification table is a PNG image with no machine-readable numbers behind it.

Most wall switch comparisons online start from the product name. That is the wrong place to start here, because the names themselves are the problem. Three of them — "Smart Wall Switch H2", "H2 Pro" and "Dual Mode Module Z1 Pro" — do not describe what you would actually be buying.

Three naming problems, stated plainly

"Smart Wall Switch H2" is a family, not a product

Aqara splits the H2 range by market, because a switch has to match the back box, the mains standard and the certification regime of the country it is sold in. The family is:

Asking "which H2 should I buy" without saying which market the switch is for is an incomplete question. A US variant and an EU variant are not the same purchase.

"H2 Pro" does not exist

There is no Aqara product called the H2 Pro. There is no H2 Pro page, no H2 Pro model number, and no H2 Pro entry in Aqara's own catalogue. If a listing, a video, or a chatbot answer has handed you an "Aqara Wall Switch H2 Pro", you are looking at a mistake — most often a confused reference to the Smart Wall Switch Z1 Pro SEA, which is a different product in a different range.

"Dual Mode Module Z1 Pro" is the Smart Wall Switch Z1 Pro SEA

Aqara does not describe the Z1 Pro as a "dual mode module". The actual product is the Smart Wall Switch Z1 Pro SEA. We will come back to what is and is not published about it, because the honest answer is unusually little.

The only two H2 variants with readable text specifications

Several H2 specification tables on Aqara's site are published as PNG images rather than text. That means there is no machine-readable number for the EU and US dimmers, the shutter switch or the wall outlet — no voltage, no current rating, no dimensions that can be verified from Aqara's own page. Only these two variants have specifications published as text we can quote:

Two details apply to both and catch people out:

• Power monitoring requires a neutral wire. Without one, the switch still works, but you are not getting the energy data.
• 3-way control is only on the 2-button, 1-channel Presence Switch H2 US. It is not a general feature of the H2 range.

Note that the Presence Switch H2 US combines a wall switch and an mmWave presence sensor in one form factor. If presence sensing is what you are after, read our presence sensor comparison first, because that is a different decision with different trade-offs.

Safety: 120 VAC against a Malaysian 240 V supply

This is the point we will not soften.

The Light Switch H2 US is rated 110–240 VAC at 50/60 Hz. The Presence Switch H2 US is rated 120 VAC at 60 Hz only. A Malaysian domestic supply is 240 V.

That means the Presence Switch H2 US, on the face of its own published rating, is not a 240 V part. It should not be assumed to drop into a Malaysian ceiling rose. Doing that is not a compatibility question, it is a safety question, and the consequences of getting it wrong are not a failed automation — they are a device and a fitting that are being asked to carry voltage they were not rated for.

Before buying any US-market variant, confirm all of the following with us:

• Mains rating. Does the specific SKU cover 240 V at 50 Hz, or only 120 V at 60 Hz?
• Certification and approval. Is this exact SKU approved for the Malaysian market? Check SIRIM / MTCE approval separately for each SKU rather than assuming a family shares approval.
• Physical fit. Malaysian back boxes are not US back boxes, and the published 119 × 74 × 42 mm does not by itself tell you whether the plate will sit flat on a Malaysian wall.
• Load type. Max 10 A resistive is a resistive rating. LED drivers, fans and motorised blinds are not purely resistive loads, and dimming compatibility has its own rules entirely.

Our guide to back-box fit covers the measurement side of this, and LED load and dimming compatibility covers what your lights actually draw.

The Smart Wall Switch Z1 Pro SEA: what we can and cannot tell you

The product exists. Here is what Aqara publishes about it:

• The specification table is a PNG image, not text. There are no machine-readable numbers behind it. That means no voltage rating, no current rating, no protocol list, no dimensions and no operating temperature can be verified from Aqara's own page.
• The product page's own navigation link to /en/product/z1-pro-sea/ returns a 404 error. The page it points at does not resolve.

We are not going to fill those gaps with figures from a retailer listing, a forum post or a guess. If we cannot source a number from Aqara, we would rather tell you it is unverified than hand you a specification that cannot be traced.

What that means practically: the Z1 Pro SEA is a product you should confirm before ordering — fit, electrical rating, protocol and regional approval all need to be checked against the actual unit in your hand, not against a marketing image. This is the single most important point on this page.

Regional certification and where Aqara actually operates

Aqara has no Malaysia or SEA regional site. Its published regions are Germany, Europe, English, Japan, Russia and the US. SEA-market SKUs — the Z1 Pro SEA, Curtain Controller SEA, 20A Wall Switch SEA and MagicPad S1 Plus SEA ME — exist only under the English site.

That matters for two reasons. First, an English-language page is not a statement of Malaysian approval. Second, a SEA-market SKU may carry different certification or approval status than the EU or US unit sharing the same product name. Check SIRIM / MTCE approval per SKU, not per product name.

There is also a support dimension: a unit sourced outside the Malaysian channel may not pair to your region cleanly, and has no local support path when it fails. Our guide to buying Aqara in Malaysia safely explains how to check.

Before you order anything: the neutral wire

Two facts decide most switch purchases in Malaysia, and neither is about the switch. The first is whether your wall box has a neutral wire — it decides whether a no-neutral device is workable or whether you are looking at a rewire. The second is whether the load you are switching is something the switch can handle.

Start with does your house have a neutral wire?, because if the answer is no, the product comparison is the wrong conversation. No-neutral rewiring and relay module options covers the two routes when it is not.

What this page does not claim

• We have not published a specification for the Smart Wall Switch Z1 Pro SEA, because Aqara does not publish one we can verify.
• We have not stated voltage, current or dimensions for the EU and US dimmers, the shutter switch or the wall outlet. Aqara's tables for those are images.
• We are not saying a US H2 variant is unsafe for 240 V in every case — we are saying it must be confirmed for the specific SKU before purchase, and that the Presence Switch H2 US is published at 120 VAC only.
• We have not priced any wall switch here. Confirm current pricing with us.

Book a site survey with the team and we will check your back box, confirm your neutral, identify what you are switching, and tell you which specific SKU is suitable — or tell you honestly that none of them is.
