Found: trigger on WiFi "signal strength" change

[Matt R]

I recall a few users asking about triggering a task when WiFi signal strength changed (specifically when the strength was low). I came across an intent broadcast that works on my phone:

Profile: WiFi Strength Changed
Event: Intent Received [ Action:android.net.wifi.RSSI_CHANGED Cat:None Cat:None Scheme:* Mime Type:* ]
Enter: Anon
A1: Flash [ Text:WiFi strength changed! RSSI = %newrssi Long:Off ]

The RSSI is available in the %newrssi variable. I have no idea if this is OS/ROM/device dependent. Just an FYI.

Interesting. Thanks for sharing! I don't really need this specific purpose atm, but I wanted to learn the new context Intent Received so I tried testing this out. Walking around my house and definitely having varying signal strengths, I didn't get the profile to fire...S4 with a custom TouchWiz based ROM... so your hunch might be right.

Profile: Testwifi (272)

Event: Intent Received [ Action:android.net.wifi.RSSI_CHANGED Cat:None Cat:None Scheme:* Mime Type:* ]

Enter: Testwifi (273)
A1: Flash [ Text:It worked! Long:Off ]

Question: how did you stumble on this intent to begin with? Intent Interceptor doesn't help here, right?

Found it using this app: https://play.google.com/store/apps/details?id=lt.andro.broadcastlogger

Thanks! Useful tool... and so is Interceptor. I confirmed that my phone users the same intent. I'll figure out why the profile isn't firing tonight after the game...

I'll figure out why the profile isn't firing tonight after the game...

Okay, for my device, I got the profile working by removing the asterisks from the Scheme and Mime fields and just leaving them blank.

Thanks again for sharing that app!

[Matt R]

Yeah, I left those blank too.  Strange that leaving it blank and entering an asterisk aren't equivalent ...

how did you know that %newrssi is the correct variable?

You can check the API documentation: http://developer.android.com/reference/android/net/wifi/WifiManager.html#EXTRA_NEW_RSSI

Here is described how Tasker modifies variable names in intents: http://tasker.dinglisch.net/userguide/en/intents.html

Also the above mentioned App Broadcast Monitor provides information about intent extras.

just tried it on my samsung galaxy s5 unrooted. Scheme and Mime Type left blank. Works just fine. :)

Good tip! Thanks Matt.
