Not completely. Ring appears to be phasing out or replacing older Ring Alarm versions, but as of August 18, 2026, Ring’s U.S. website lists newer Ring Sensors glass-break and flood/freeze models. The claim that Ring has abandoned both product categories is therefore misleading without specifying the generation.
Why people think Ring discontinued them
Several different situations can look like a discontinuation:
- An older product page may be removed or replaced.
- A page may show a “notify me” form instead of a purchase button.
- Retailers may sell through their remaining inventory.
- Ring may use “discontinued” to describe an older model while continuing the category under a new name.
- Availability may vary by country or temporarily reflect low stock.
That appears to be what happened here. The older Ring Alarm Flood & Freeze Sensor page currently displays an availability notification form, while Ring’s newer product collection lists a Flood & Freeze Sensor (Newest Model). Ring’s current Glass Break Sensor page likewise identifies a newer model.
What Ring sells now
| Product | Status | Connectivity | Base station |
|---|---|---|---|
| Ring Alarm Flood & Freeze Sensor | Older generation; limited availability on Ring’s site | Z-Wave | Required |
| Flood & Freeze Sensor (Newest Model) | Current Ring Sensors listing | Amazon Sidewalk; Z-Wave with Ring Alarm | Not required when Sidewalk is available |
| Ring Alarm Glass Break Sensor | Older Alarm generation | Ring Alarm/Z-Wave ecosystem | Required |
| Glass Break Sensor (Newest Model) | Current product | Amazon Sidewalk or Z-Wave | Required for Z-Wave |
Ring announced the newer sensor family at CES on January 6, 2026, with planned availability beginning in March. The newer line is designed to connect through Amazon Sidewalk without a dedicated alarm hub where Sidewalk coverage is available, while also supporting use with Ring Alarm systems. See Ring’s CES announcement and Ring Sensors overview.

Is the flood/freeze sensor still available?
Yes, the newer Flood & Freeze Sensor appears in Ring’s current U.S. home-security collection. The collection showed a $39.99 list price and a $29.99 promotional price on August 18, 2026.
The older Alarm model is different. It uses Z-Wave, requires a Ring Alarm or Ring Alarm Pro Security Kit, reaches up to 250 feet from the Base Station under Ring’s stated conditions, uses one non-rechargeable 3V lithium battery—identified in support instructions as a CR123A—and has a maximum stated battery life of three years. Its stated operating range is 32°F to 120°F.
Ring says the newer sensor sends alerts when it detects water or when temperature drops below 40°F. The 40°F alert threshold should not be confused with the sensor’s 32°F–120°F operating range.
What changed between generations?
Older Ring Alarm sensors
The older accessories were built around Ring Alarm and Z-Wave. The older Flood & Freeze Sensor explicitly requires an Alarm or Alarm Pro Security Kit. The older Glass Break Sensor is also an Alarm ecosystem device.

- Monitor indoor spaces — Track temperature and humidity levels in basements, attics, crawl spaces, garages, and more. Indoor use only.
- Stay ahead of costly issues — Get alerts that help you catch mold risks or moisture swings early, so you can act fast.
- No base station required — connects over Amazon Sidewalk for simple, flexible coverage throughout your home and beyond (Amazon Sidewalk required for use; coverage may vary).
- This device provides general indoor temperature and humidity information only. Do not use readings for medical or safety decisions.
For the older Flood & Freeze Sensor, Ring’s setup path is:
- Open the Ring app.
- Tap Set Up a Device.
- Choose Set up a Ring Alarm Base Station or Z-wave Sensor.
- Follow the in-app instructions.
- Twist open the sensor when prompted and pull out the clear activation tab.
- Allow the Base Station to find the sensor.
To replace its battery, disarm Ring Alarm, remove the cover, replace the battery with a CR123A using the correct polarity, wait for the blue LED to glow for three seconds after pairing, and replace the cover. Ring’s setup instructions and battery guidance apply to the older Alarm device.
Newer Ring Sensors
The newer models are built around Amazon Sidewalk and can also be added to an account with a Ring Alarm or Alarm Pro Base Station. A base station is not required when Sidewalk connectivity is available, but coverage and service availability vary.
The newer Glass Break Sensor uses three AA batteries and has an approximate battery life of up to two years. Ring lists Sidewalk or Z-Wave connectivity; Z-Wave operation requires a Ring Alarm Base Station. A battery-powered sensor may remain powered during an internet or power outage, but alerts still depend on the available communication path, Sidewalk gateways, local equipment, network conditions, and service availability. No sensor can guarantee delivery during every outage.

Probably, if they remain connected, have a functioning battery, and continue to generate alerts. Ring still publishes setup, battery-replacement, and troubleshooting material for the older devices. More importantly, Ring’s software-security-update table lists both Glass Break Sensor and Flood & Freeze Sensor for security updates through at least December 31, 2030.
That date is not a guarantee that every device will work unchanged until 2030. It is a published security-update commitment—not a promise of indefinite retail stock, identical replacement hardware, continued feature development, or successful enrollment of every old model in every future version of the Ring app.
If you own one:
- Record the exact model and generation.
- Replace the battery before assuming the sensor has failed.
- Confirm that it appears in the Ring app.
- Trigger an appropriate test alert and verify that notifications arrive.
- Ask Ring support whether a failed unit would be replaced with the same generation or a newer model.
Avoid paying an inflated price for used or old marketplace stock unless the seller is reputable and accepts returns.

What each sensor actually detects
Glass break
A glass-break sensor listens for the acoustic signature of breaking glass. It is not the same as a door or window contact sensor, which detects opening. A window can be opened without shattering, so using both can provide better coverage.
Ring’s older installation guidance recommends placing the sensor at least seven feet above the floor and within 25 feet of the protected window or glass door. Mount it on a clean, dry surface with suitable tape or anchors and configure the alarm modes in which glass-break detection is active. Room acoustics, window type, distance, obstructions, and false-alarm controls can affect performance. See Ring’s installation guidance.
Flood and freeze
Place the sensor near likely trouble spots such as sinks, bathtubs, showers, refrigerators, water heaters, toilets, basements, and other leak-prone areas. It provides early warning; it does not shut off water, protect every pipe, or replace insulation and sump-pump maintenance.
For serious leak risk, consider a system with automatic shutoff, multiple remote probes, sump-pump monitoring, battery-backed or cellular communications, and professional monitoring.
Which model should you buy?
- Starting a new Ring setup: Choose the current Ring Sensors model first. Confirm Sidewalk coverage, or plan on using a Ring Alarm Base Station for Z-Wave integration.
- Already using Ring Alarm: The newer sensor may fit, but verify the exact generation and app compatibility before replacing a working older device.
- Considering old stock: Buy only if the price is reasonable, the seller is trustworthy, the item is returnable, and you specifically need the older Ring Alarm/Z-Wave arrangement.
- Need maximum flood protection: Look beyond a basic alert sensor to whole-home monitoring and automatic shutoff. Options such as Flo by Moen, YoLink, or Aqara use different hubs, protocols, and service models; they are not drop-in Ring replacements.
- Need professionally monitored security: Compare systems such as SimpliSafe or ADT, verifying their current glass-break and water-detection options. Professional installation and monitoring may be excessive for a renter or someone seeking a simple self-installed alert.
Do not assume a third-party Z-Wave device is officially supported by Ring Alarm. Likewise, a generic Wi-Fi leak sensor may stop reporting when the router or household power fails, and a camera-based glass-break feature is not necessarily equivalent to a dedicated acoustic sensor.

Bottom line
Ring has not discontinued glass-break and flood/freeze detection as product categories. It appears to be retiring or transitioning older Ring Alarm versions while continuing both products in a newer Ring Sensors generation. Existing devices are listed for security updates through at least December 31, 2030, but buyers should confirm the exact generation, connectivity method, base-station requirement, Sidewalk availability, subscription needs, and current price before purchasing.
