There was recently a question about a wi-fi signal strength indicator on the Photon. I considered a few other things like a full RGB LED or a red-green-yellow 3-pin LED, but eventually decided on a plain LED. The brightness indicates the signal strength. Since it’s hard to determine how bright the L…

I think the green/amber/red would be a much better implementation. I don’t really care what the RSSI is. What I care about is which of these 3 states my device is in the wifi is strong and should not be a problem the wifi is sketchy, if you are having problems, it’s likely the wifi the wif…

Without any extra hardware RGB.control(true) and RGB.color() would be an option too.

[image] vinistois: the wifi is strong and should not be a problem the wifi is sketchy, if you are having problems, it's likely the wifi the wifi is too weak, don't expect anything to work. I like that idea. What are the RSSI values that you found that can indicate those states? Whic…

This is a different version of the code that blinks the D7 LED from 1 to 4 times depending on the Wi-Fi signal strength. I set the boundaries at -40, -60, and -80. You’ll probably want to fine-tune the values, but that’s a reasonable place to start. #include "Particle.h" // You pretty much need to…

This code is great @rickkas7 . I added some text for serial monitor and colours as suggested by @vinistois and @ScruffR . #include "Particle.h" // You pretty much need to use system thread enabled (or manual mode) because otherwise when you go out of range, // loop stops running when the cloud conne…

I like that idea. What are the RSSI values that you found that can indicate those states? Which RSSI level probably will mean a sketchy condition? And which will be too weak?
