Yes, you can query Alexa. If your sensor name is ATTIC TEMP HUMIDITY, as it is in my own home, you can say "Alexa, what is the temperature of the attic temp humidity sensor?" And Alexa will return with "The attic temp humidity sensor temperature is 111 degrees."

Versatile & Efficient
The weatherproof temperature sensor has many applications, including pool/hot tub & fish tank water, wood boiler, fridge and deep freezer, livestock water trough, milk, beer, wine, water, steam and pipe temperature monitoring. Additional uses include composting and HVAC/heating/cooling/ventilation management (YoLink smart plugs and switches purchased separately).
Use the YoLink smartphone app to remotely monitor the temperature of your home, rental property, condo, summer home, or business. YoLink’s industry-leading long-range communication allows for placing the sensor in your out-buildings, separate garage buildings, barns, greenhouse, etc.
Monitor any water temperature: pool, hot tub, aquarium, boilers, water trough, etc.
Monitor temperatures of surfaces when the sensor is affixed to the object, such as clamping the probe to a hot water pipe

FAQ
Is there an Alexa command that will read out the temperature?
Does the temperature sensor (YS8004) have D2D capabilities?
Yes, the YoLink temperature sensor model YS8004 supports D2D (Device-to-Device) functionality. For instance, if you wish for it to activate another device upon reaching a low temperature, the sensor must be in low-temperature alert mode during pairing.
I have the hub already set up and online but when adding a temperature sensor it shows offline.
Once you set up the network for your YoLink hub, please press the "set" button on the temperature sensor to activate your temperature sensor.
How do I replace the battery of the Temperature sensor YS8004?
To replace the battery for your YoLink YS8004 temperature sensor, follow these steps:
Use a pair of tweezers to carefully remove the four sealed rubber pads located at the base of the device. Use a screwdriver to unscrew the screws at the base of the device, and remove the base.
Remove the two old batteries and replace them with two new AAA lithium batteries.
Close and secure the base by reinstalling and tightening the four screws.
Finally, reattach the four sealing rubber pads to the base of the device.
Is the sensor waterproof?
Yes, the IP rating is IP67.
