Exploring the Interplay of Wireless Devices (Android Phones, TV’s, Windows, Linux, and MacBook) and Home Automation Devices in Smart Home Environments
Recreated a smart home scenario involving a combination of general Wireless devices with different operating systems (Android Phones, TV’s, Windows, Linux, and MacBooks), smart home automation devices, and Echo devices.
Here are the Device details used in the test.

Home Automation Devices Details:

TEST SETUP DIAGRAM:
SCENARIO-1: LATENCY TEST ON HOME AUTOMATION DEVICES (when Network is not busy)
This is a scenario where are only 3 Wireless devices (Android phones) are actively used, and all the smart home automation devices are initiated with commands remotely.
1.?Connect the Access point (DUT) and cluster 3 Wireless devices (Android phones) to the traffic generator.
2.??Connect all the 3 Wireless devices (Android phones) to the AP’s 2.4GHz SSID.
3.??Connect the Echo device (wirelessly) to the AP’s SSID from the Alexa App.
4.??Power ON the Home automation devices i.e.? Zeb-SP110 10A Smart Plug, Tapo C100 V1 Camera and Wipro garnet Smart bulb and connect them to the AP’s 2.4GHz SSID (wirelessly) from their respective applications.
5. Once all the home automation devices are paired with Alexa Echo and connected wirelessly to the same 2.4GHz SSID, initiate commands from the developer console (i.e., the controller) in the Alexa Simulator continuously for a duration of 5 minutes. And Live stream a Video on the Tapo Camera.
6.?Simultaneously stream video on all the 3 Android Phones (Wireless devices).

7.?For the entire test duration of 5 minutes, initiate commands to the home automation devices from the developer console (i.e., the controller) 60 times. And record the latency after initiating each command.
SCENARIO-2: LATENCY TEST ON HOME AUTOMATION DEVICES (when Network is busy)
This a scenario where 17 Wireless devices (Android Phones, TV’s, Laptops of different OS) are actively used, and all the smart home automation devices are initiated with commands remotely.
1.?Connect the Access point (DUT) and cluster all 17 Wireless devices with different OS (Android Phones, TV’s, Windows, Linux, and MacBook) to the traffic generator.
2.?Connect all the 17 Wireless devices with different OS (Android Phones, TV’s, Windows, Linux, and MacBook) to the AP’s 2.4GHz SSID.
3.?Connect the Echo device (wirelessly) to the AP’s SSID from the Alexa App.
4.?Power ON the Home automation devices i.e.? Zeb-SP110 10A Smart Plug, Tapo C100 V1 Camera and Wipro garnet Smart bulb and connect them to the AP’s 2.4GHz SSID (wirelessly) from their respective applications.
5.?Once all the home automation devices are paired with Alexa Echo and connected wirelessly to the same 2.4GHz SSID, initiate commands from the developer console (i.e., the controller) in the Alexa Simulator continuously for a duration of 5 minutes as shown above. And Live stream a Video on the Tapo Camera.
6. Simultaneously stream video and browse websites on 9 wireless devices (Android Phones & TV’s), Download FTP and HTTP protocol files on the other 8 wireless devices which includes Windows, Linux, and MacBook.
7. For the entire test duration of 5 minutes, initiate commands to the home automation devices from the developer console (i.e., the controller) 60 times. And record the latency after initiating each command.
LATENCY TEST COMPARISON
Upon comparing the latency recorded in both scenarios, the following observations were made:
There was a significant increase in the latency of Home Automation devices when the network was busy and multiple general wireless devices with different operating systems (Android Phones, TV’s, Windows, Linux, and MacBooks) were actively used for various purposes such as streaming videos and downloading files.
Happy Learning!
Fascinating research! Can't wait to read your findings on the impact of wireless devices on home automation devices. ????

1 年I do keep hoping you put a known good, airtime fairness openwrt box like an old fashioned wndr3800 into the chamber. 2.5s? you gotta be kidding me...

1 年Great idea, a good start! But most homes are much larger than the tested environment. :) When it comes to wireless tech at realistic distances, there is this thing called the inverse square law, and another called wifi airtime fairness, to cope with. Having all this gear stuffed so close together will actually overdrive the receivers. But that too is a cool result that I would love to see what it looks like on a test as far too many people stuff the tv and the AP a few inches from each other, rather than running a cable, as google fiber showed in this test series here: https://apenwarr.ca/diary/wifi-data-apenwarr-201602.pdf - however, I do praise this test series regardless!
