The Hatch Rest and Yogasleep Dohm Classic represent two very different philosophies on nursery sound machines. The Hatch Rest is a Wi-Fi-connected device combining a sound machine, night light, and time-to-rise alarm, all controlled through a smartphone app. The Dohm Classic uses a real internal fan to produce white noise, with a physical switch and no app required. This comparison covers the specs, differences, and parent experiences for each.

Sound Generation: How They Differ
This is the core difference between these two machines. The Dohm Classic produces white noise mechanically using a real internal fan. The sound comes from air moving through adjustable openings in the housing. You twist the outer shell to change the tone and adjust between two fan speeds. Because the sound is generated by a physical fan, it does not loop and has a natural, consistent quality that some people prefer over digital recordings.
The Hatch Rest uses a digital speaker to play pre-recorded and synthesized sounds. The 2nd generation model includes at least 10 sound options: white noise, rain, ocean, birds, wind, water, thunderstorm, dryer, heartbeat, and fan simulation. Additional sounds may be available through the Hatch Sleep app, though some library content requires a Hatch+ subscription (paid separately).
The practical difference: the Dohm does one thing (white noise) using analog mechanics. The Hatch does many things (multiple sounds, light, alarm) using digital technology. Parents who find that a single consistent white noise is all they need may appreciate the Dohm’s simplicity. Parents who want variety, programmable routines, or the ability to adjust settings from another room may value the Hatch’s app-driven approach.
Smart Features and Connectivity: How They Differ
The Hatch Rest connects to your home Wi-Fi network and is controlled primarily through the Hatch Sleep app (available for iOS and Android). Through the app, you can set schedules, create bedtime routines that transition through different sounds and light colors, set a time-to-rise alarm that changes the light color in the morning, and adjust volume and brightness remotely. Touch controls on the device itself allow basic operation without the app.
The Dohm Classic has no smart features. It has a physical on/off switch on the back and the two-speed fan toggle. You adjust the tone by rotating the outer shell. There is no app, no Wi-Fi, no Bluetooth, and no programming capability. It turns on, it makes white noise, and it stays on until you turn it off.
The Hatch’s connectivity is a strength for parents who want to manage sleep routines from their phone or set automated schedules. It can also be a frustration when Wi-Fi drops or app updates introduce bugs, both of which appear in parent reviews. The Dohm’s lack of connectivity means there is nothing to troubleshoot, update, or subscribe to, but it also means you walk into the room to change anything.
Night Light Functionality: How They Differ
The Hatch Rest includes a built-in night light with a full color spectrum. You can set any color and adjust brightness through the app. Many parents use this for nighttime feedings (a dim red or orange light) or as a time-to-rise indicator for toddlers (the light turns green when it is okay to get out of bed). The light and sound can be programmed independently or as part of a combined routine.
The Dohm Classic does not include any light functionality. If you need a night light, you would need a separate device. Some parents prefer this separation, keeping the sound machine as a single-purpose device and choosing a separate night light that they can position independently in the room.
For nurseries where a combined device reduces clutter, the Hatch serves double duty. For parents who prefer dedicated, simple devices, the Dohm plus a separate night light may be the preferred setup.
What Parents Are Saying
About the Hatch Rest (2nd Gen)
Common praise: The app-based control is the most frequently praised feature, with parents highlighting the ability to adjust sound and light from outside the nursery without disturbing a sleeping child. The time-to-rise feature is highly rated among parents of toddlers. The variety of sound options lets parents experiment to find what their baby responds to. The compact size gets positive mentions for fitting easily on a shelf or dresser.
Common complaints: Wi-Fi connectivity issues are the most common criticism. Some parents report the device occasionally disconnects from the app, requiring re-pairing. The Hatch+ subscription (required for some premium features and expanded sound libraries) is a point of friction for parents who feel core features should not have ongoing costs. A smaller number of reviewers note that the digital white noise does not sound as natural as a fan-based machine.
About the Yogasleep Dohm Classic
Common praise: The natural, non-looping sound quality is the top positive theme. Parents and adult users consistently describe the fan-based noise as more soothing and less “artificial” than digital alternatives. The simplicity of operation (switch on, adjust tone, done) is frequently praised. Durability is another common theme, with multiple reviewers reporting years of daily use without issues.
Common complaints: The limited sound options (only fan-based white noise, no rain/ocean/lullaby options) are the most common criticism. Some parents note that the mechanical fan can develop a slight rattle over time. The lack of a night light means purchasing an additional device. A few reviewers mention the 7-foot power cord as inconvenient for certain room layouts, and the machine cannot operate without being plugged in.

Who Might Prefer Which
- The Hatch Rest may be a better fit if you: want to control the sound machine remotely via your phone, value having a combined sound machine and night light in one device, plan to use the time-to-rise feature as your child transitions to toddlerhood, or want multiple sound options to find what works for your baby.
- The Yogasleep Dohm Classic may be a better fit if you: prefer a natural, fan-generated white noise over digital recordings, want a simple device with no app, Wi-Fi, or subscription requirements, prefer a device with minimal points of failure (no software updates, no connectivity issues), or primarily need consistent background noise rather than a multi-feature sleep system.

FAQ
Does the Hatch Rest work without Wi-Fi?
The Hatch Rest 2nd Gen has touch controls on the device that allow basic operation (turning on/off, cycling through presets) without Wi-Fi. However, the full feature set, including scheduling, custom routines, and the time-to-rise alarm, requires the Hatch Sleep app and a Wi-Fi connection. If your Wi-Fi goes down, the device continues playing whatever sound and light setting it was last using.
Is the Dohm loud enough for a nursery?
The Dohm Classic reaches approximately 57 dB at 6 feet on its highest setting, as measured by the manufacturer. The AAP recommends that sound machines in infant sleep environments be kept below 50 dB when placed near the crib. Positioning the Dohm across the room rather than next to the crib can bring the sound level at the baby’s ear within recommended limits. This guidance applies to all sound machines, including the Hatch Rest.
Do you need the Hatch+ subscription?
The core features of the Hatch Rest (sound machine, night light, time-to-rise, basic app control) work without a subscription. Hatch+ unlocks additional sound options, sleep content, and premium features. Whether the subscription adds value depends on how many features you plan to use beyond the basics.
Can the Dohm Classic be used for travel?
The Dohm Classic requires a 120V AC power outlet and does not have a battery. It is portable in the sense that it can be unplugged and packed, but it needs wall power wherever you go. For travel, Yogasleep offers portable models like the Yogasleep Hushh or Rohm that are battery-powered and designed for on-the-go use.
Which is louder, the Hatch Rest or the Dohm?
Direct volume comparisons are difficult because Hatch does not publish a maximum decibel rating for the Rest 2nd Gen. The Dohm Classic reaches approximately 57 dB at 6 feet. Anecdotally, parent reviews suggest the Dohm can produce a fuller, more room-filling sound due to its mechanical fan, while the Hatch’s digital speaker is described as adequate for most nursery sizes but may not mask loud external noise as effectively in larger rooms.
