How it works
Is it Cool???
Sometimes
Name your home
- Choose the name carefully
- Good name is hard
- Ambiguity
- Make sense
- Easy to remember
- Easy to say
- Distinguishable
- Same as Shortcut
- A way to review rethink and redesign your home
Know your home
- Status of everything automated
- On/Off
- Brightness
- Temp/Humidity/AQI
- Complex information
- Statistics of everything
- Power usage
- Habits & Pattern
- Data Driven Home?
- Scenario
Wearing uniform rather than Pajama is hard
- Diploma
- Trainings & Exams
- Apprenticeship
A lot of fun
Is it Cool???
Sometimes
makes me feel
that
I'm out of my mind
Google Assistant is dumb
I believe the same to Alexa, Cortona, Siri, XiaoAi....
or any similar species you can name
Google Assistant is dumb
Big room is tricky
One talk at a time!
Baby is nuke-weapon!
Google Assistant is dumb
Dictation accuracy is tricky
- Dictation is to find the closest candidate
- "Closest" is defined by vector distance
- A proper candidate list is key
- Too many, too crowded
- Too few, missed the answer
- Google is smart by context
- Hint word in key
- Good luck with out of context keyword
- Turn on Sol
- Sunrise! Sunrise! Sunrise for god's sake
Google is down!
Yes, the mighty Google is down!
TWICE!
In a month!
Internet is down
Almost every night for Xiaomi
A few times for Itead
Internet is slow/unstable
Vendor server is down
WIFI is DOWN
- Easily get WIFI over crowded
- Move all smart devices to 5G
- "Dumb" devices only works on 2.4G
- Setup Dedicate SSID for home control
- Coverage is more critical
Reliability
Be careful with critical devices

- Gate Controls!
