In September, we have released the Wireless Tag "smart home" skill. Due to limitation of the "smart home skill" category as defined by Amazon, although the skill allows actions such as "arm" or "beep" by voice command, we could not make Alexa return much useful information about each sensor such as temperature or motion state. 

Today, we are happy to announce the "Wireless Tag (Informational)" skill has passed certification and is now available to install. This skill is meant to supplement and be used together with the existing Wireless Tag smart home skill. As the name suggests, this skill is focused on having Alexa return useful information. 

Try saying: "Alexa, ask Wireless Tag for the lowest temperature last week." to know which sensor recorded the lowest temperature and how much.
"Alexa, ask Wireless Tag for the lowest temperature in Living Room last month".
"Alexa, ask Wireless Tag for the highest temperature in Fridge last week".

"Alexa, ask Wireless Tag for the temperature at boiler room yesterday." to know the average temperature yesterday there.
"Alexa, ask Wireless Tag for temperature at Living Room" to know the current temperature. 

Instead of "temperature", you can also ask about "humidity", "brightness", "moisture" or "motion state".

"Alexa, ask Wireless Tag what happened today" to have Alexa read back event history today, or "Alexa, ask Wireless Tag what happened at Fridge last week" to have Alexa read back events only related to the tag "Fridge", including what time Fridge was opened or about any temperature abnormalities, starting from the most recent.

You can also say...
"Alexa, ask Wireless Tag if Front Door is open"
"Alexa, ask Wireless Tag if Car Key is out of range"
"Alexa, ask Wireless Tag about the signal at Tag 1"

Here is a list of all possible things you can say (after "ask Wireless Tag", and skip the first column). 

The older smart home skill is better at recognizing unique names of tag you have given, while the "Wireless Tag (Informational)" skill recognizes from a list of most common 100 or so tag names such as "Living room" (complete list here) plus a number, which should cover over 95% of all names people have ever given to their sensor tags. If the skill has trouble recognizing your tag name, try to rename it to one on the list.
