MOES is a budget smart home brand, and the PTH-24E is its plug-in detector for carbon monoxide and combustible gas. The same unit also reads temperature and humidity. The store’s price changes from time to time, so check the current price at MOES before you decide.
This is a research-based look, not a bench test. It draws on the MOES spec sheet, the brand’s policy pages and the written reviews on its own product page, and the text says so whenever a point comes from the brand.
The short version: it is a good fit if you want a self-contained unit with a screen and no app, and the wrong choice if you want alerts on your phone.
What the PTH-24E Measures
MOES lists four readings for this model in a single housing: carbon monoxide, LPG and natural gas, temperature and humidity.
According to the spec sheet, the carbon monoxide range is 0 to 999 PPM, and the alarm defaults to 51 PPM. Combustible gas is graded on four levels, and the alarm sounds from 5% LEL upward.
The same 2-inch IPS screen also shows temperature and humidity, so the unit doubles as a room readout even when no gas is present.

How the Alarm and Display Work
The spec sheet lists an 85dB built-in alarm plus a four-stage color scheme on the display. The colors run green, yellow, orange and red as the reading climbs.
The detector has no WiFi, no Tuya app support and no phone notifications. Pairing is not part of the process: you plug it in, and the screen and alarm are the only places the readings show up.
That is the main design choice to understand. MOES builds most of its catalog around the Tuya and Smart Life apps, and this detector sits outside that world.
Two more practical details apply to MOES detectors in general: most models include a manual test button, and the units run on wall power with a battery backup.
Build, Size and Placement
MOES specifies a flame-retardant ABS housing, sized 105 by 55 by 52mm when the plug head is fitted. The input range is 100 to 220V, and the box includes US, EU and UK plug heads you can swap, so the same unit suits several regions.
Nothing here involves wiring or pairing. You push the unit into a wall outlet, and that is the whole installation, with no menu to configure.
Where to plug it in
The right outlet depends on what you want to catch. An outlet near the stove, water heater or gas furnace puts the unit close to where a gas reading is most useful, while outlets by the bedrooms and an attached garage suit the carbon monoxide side.
The manual that comes with the unit is the place to confirm MOES’s own placement advice before you settle on a spot.
What Owners Say
The product page on MOES’s own store carries three written reviews, and all three are five stars. That is a very small sample, so treat it as a few voices and not a consensus.
One reviewer runs a unit at home and a second in an RV, and calls it highly responsive to the gases it watches for.
Another reviewer says their unit picked up small amounts of natural gas escaping from a bathroom vent. It is a single account that cannot be verified here, but it describes the situation a detector like this is meant for.
No complaints appear in those three reviews. With so few, though, there is little evidence yet about how the unit holds up over years of use.
Who It Suits, and Who Should Skip It
A good fit if you want
- A standalone unit that works as soon as it is plugged in
- A live temperature and humidity readout beside the gas readings
- One detector design that can move between a house, an RV or another region, thanks to the swappable plug heads
Look elsewhere if you want
- Alerts on your phone or a link to a smart home app, which this unit does not offer
- A detector that joins a wider automation setup
If you want app control elsewhere in the home, MOES sells that kind of hardware too, typically managed in the Tuya or Smart Life app. The detector is a separate purchase, not an add-on to those devices.
Pairing it with other MOES devices
MOES also sells switches in WiFi, Zigbee and Matter versions. WiFi models join your router directly, Zigbee models need a gateway but scale well across a house, and Matter models work natively with Apple Home, Google Home, Alexa and SmartThings.
Those devices run through apps, so a room can combine the two jobs: this detector for standalone readings and an app-connected switch for the lights. Each one is bought separately.

About MOES, Returns and Warranty
MOES says it has been designing and building smart home devices for more than five years. It also reports more than 400,000 active users in over 100 countries. Those are the brand’s own figures and they are not independently audited.
MOES builds on Tuya’s platform instead of running its own cloud, which is part of how it keeps prices low. The PTH-24E needs none of that platform, since it has no app.
MOES’s own store shows about 390 product reviews across its whole catalog, but most of them belong to other products, so the detector’s own three are the ones that matter for this page.
Standard shipping is free on orders above $29.90 in most countries, and smaller orders carry a $5 fee. Check the current price at MOES, since the store’s prices shift.
MOES gives you 60 days from delivery to send an item back, as long as it is unused, undamaged and still in its original packaging. A return starts with an email to MOES, and the reply carries a link that opens the process.
Once MOES approves a return, the refund goes to the payment method you used, typically in 3 to 5 business days.
The 2-year warranty is a separate layer that applies to hardware defects. Returns suit a change of heart or a poor fit, and the warranty is there for faults that surface after the return window has closed.
By default, orders leave from China, though MOES draws on regional warehouses when stock permits. Standard delivery to the US is typically quoted at 7 to 21 business days, and DHL or FedEx are quicker at extra cost. Duties and import taxes fall on the buyer and are not part of listed prices.
Questions Buyers Ask
Does the PTH-24E connect to an app?
No. There is no WiFi, no Tuya app support and no phone alerts. It works as a standalone unit with its own display and alarm.
What does it detect?
Carbon monoxide, LPG and natural gas, plus temperature and humidity. The carbon monoxide alarm starts at 51 PPM by default, and the gas alarm starts at 5% LEL.
Will the plug fit outside the US?
It ships with plug heads you can swap for US, EU or UK outlets, and it accepts 100 to 220V. MOES sells separate US and EU collections for some products, so check that the listing names your region.
How long does delivery take?
MOES packs orders within 24 hours, and standard delivery to the US is typically quoted at 7 to 21 business days, while the DHL and FedEx options cost extra and arrive faster.
Should I test it after plugging it in?
Most MOES detector models have a manual test button, and one press after you plug the unit in shows whether the alarm and the screen both respond. The units also carry a backup battery, which is worth checking every few months, much as you would with a smoke detector.
What if the display stays blank?
A screen that stays blank even with fresh backup batteries suggests a hardware issue and not a setup mistake, which is what the 2-year warranty is for. Email MOES and refer to the warranty.
The Verdict
The PTH-24E makes sense for a specific buyer: someone who wants four readings and an on-unit 85dB alarm without installing an app. The spec sheet is clear, the screen shows live data, and the return and warranty terms are straightforward.
It is not a smart device, and MOES does not present it as one. If phone alerts matter, look at a different product. If a self-contained plug-in unit sounds right, browse MOES’s range at the MOES store and look for the PTH-24E, and the 60-day return window leaves room to confirm it suits your home.
