Data from the official Aeotec and YoLink sites.
2026 verdict
For an outdoor opening, the YoLink Solar Outdoor Door Sensor is the better of these two contact sensors.
It is IP67 sealed, charges a capacitor from its own solar panel so there is no battery to change, and reaches its hub from up to 2,000 ft over LoRa, with Alexa and Home Assistant through the YoLink account and Apple Home, SmartThings and Matter through the YoLink Local Hub. The Aeotec Multipurpose Sensor is the indoor specialist: it reports open and close across wide or crooked gaps and adds temperature and vibration sensing with temperature alerts, through SmartThings, Google Home, Alexa or Home Assistant on a Zigbee hub. The Aeotec side pays for that with a CR2450 cell that drains quickly, and both still need a hub. Pick the YoLink Solar Outdoor Door Sensor for exposed outdoor openings and the Aeotec Multipurpose Sensor for difficult indoor frames that need more than contact.

What the differences mean
Indoor or outdoor
The YoLink Solar Outdoor Door Sensor is IP67 rated and made for driveway gates, pool entries, sheds and fences. The Aeotec Multipurpose Sensor is an indoor sensor, so exposed outdoor openings are outside its design.
What each one senses
The Aeotec Multipurpose Sensor reports open and close, temperature and vibration or orientation, and can fire temperature alerts. The YoLink Solar Outdoor Door Sensor senses open and close with left-open reminders, but no temperature, vibration, motion or occupancy.
Power
The YoLink Solar Outdoor Door Sensor runs from a solar-charged capacitor and never needs a battery, though it does need daylight. The Aeotec Multipurpose Sensor uses a CR2450 cell rated around a year and owners often see much shorter life.
Radio and range
The YoLink Solar Outdoor Door Sensor uses LoRa and reaches up to 2,000 ft to the hub, which is why it suits a distant gate. The Aeotec Multipurpose Sensor is a Zigbee device that needs a coordinator in range and repeats nothing on the mesh.
Smart home platforms
The Aeotec Multipurpose Sensor works with SmartThings, Google Home, Alexa and Home Assistant through a Zigbee hub. The YoLink Solar Outdoor Door Sensor works with Alexa and Home Assistant through the YoLink account and with Apple Home, SmartThings and Matter through the YoLink Local Hub.
Which one to buy if
- the opening is a gate, shed or other outdoor spot
The YoLink Solar Outdoor Door Sensor is IP67 sealed and made for outdoor openings, while the Aeotec Multipurpose Sensor is an indoor device.
- the indoor frame is uneven or the halves cannot sit close together
The Aeotec Multipurpose Sensor is known for reading closed across wide, misaligned and right-angle gaps that trip up plain contact sensors.
- you want temperature or vibration automations
The Aeotec Multipurpose Sensor adds temperature and vibration sensing and temperature alerts, which the YoLink Solar Outdoor Door Sensor does not offer.
- you never want to change a battery
The YoLink Solar Outdoor Door Sensor runs from a solar-charged capacitor, while the Aeotec Multipurpose Sensor burns through a CR2450 quickly.
- the sensor has to sit far from the hub
LoRa carries the YoLink Solar Outdoor Door Sensor up to 2,000 ft back to its hub, beyond the usual reach of a Zigbee sensor.

What owners say
Owners of the Aeotec Multipurpose Sensor highlight how it reads closed on awkward doors, casement windows and even through a screen, and they like the temperature and vibration reports they turn into automations, such as attic monitoring or a dryer-done alert. Their common complaints are a CR2450 cell that drains in weeks to months, sometimes fixed with a USB-to-CR2450 adapter, and a SmartThings presentation that splits the unit into two separate contact and temperature devices on a product that no longer receives firmware updates.
Frequently Asked Questions
Which is better overall: Aeotec Multipurpose Sensor or YoLink Solar Outdoor Door Sensor?
For an outdoor opening the YoLink Solar Outdoor Door Sensor wins, with IP67 sealing, solar-charged operation and up to 2,000 ft of LoRa range. For an indoor door or window with an awkward gap, the Aeotec Multipurpose Sensor is better, since it reads closed across wide or angled gaps and adds temperature and vibration sensing.
What is the biggest difference between the Aeotec Multipurpose Sensor and the YoLink Solar Outdoor Door Sensor?
Where each is meant to live and what it senses. The Aeotec Multipurpose Sensor is an indoor Zigbee sensor that reads contact, temperature and vibration, while the YoLink Solar Outdoor Door Sensor is a weather-sealed LoRa sensor for outdoor openings that reads open and close only.
Does the YoLink Solar Outdoor Door Sensor need a battery?
No. The YoLink Solar Outdoor Door Sensor charges a hybrid layer capacitor from its built-in solar panel, so there is no battery to replace as long as the mounting point gets daylight. The Aeotec Multipurpose Sensor uses a replaceable CR2450 cell.
Do these sensors work with Apple Home or Matter?
The Aeotec Multipurpose Sensor supports neither Apple Home nor Matter. The YoLink Solar Outdoor Door Sensor reaches Apple Home, SmartThings and Matter through the YoLink Local Hub, and works with Alexa and Home Assistant through the YoLink account.
Who should buy the Aeotec Multipurpose Sensor?
SmartThings, Hubitat or Home Assistant owners with an indoor door or window where the two halves cannot sit close or aligned, especially anyone who wants temperature and vibration sensing and does not mind a short battery life.
Who should buy the YoLink Solar Outdoor Door Sensor?
Anyone monitoring a distant outdoor gate, pool entry, shed or fence who wants the toughest seal, no battery changes and long LoRa range, provided a YoLink hub is in place and the mounting point gets daylight.
