Has anyone else noticed that when launching the Kasa Android app it sends out some sort of broadcast that ESP8266 devices respond to? Both of my Teckin SP-23s switch the relay on when I launch Kasa!
Is this a bug in the ESP8266 firmware, or just a feature of ESP8266s?
Yep I mainly use Tasmota, I have it on around 8 Sonoffs but I still have a Sonoff on stock firmware (ewelink) and again no issues when opening up Kasa for me. Very odd!
I may try ESPHome at some point, if I do I’ll post back and see if it happens to me also.
The same happens to me but I have the IOS app. I have no idea why it happens. Yesterday I was restarting my router and I found all of my Teckin SP-23s ESPHome’s turned on. It must have something to do with the tp link plug sending out a broadcast.
That’s interesting, so it sounds ESPHome related then potentially. I wonder how the firmware differs?
EDIT: BTW, this happens without even having a TP-Link device on the network. When I launch the app it switches the relays on both SP23s without any TP-Link device connected.
Hopefully Otto will see this here and might have an idea…
If I get a change I may be able to use wireshark to find out what the TP link app is doing, it could be something as simple as scanning a certain port on your local network.
Just read something about this issue a few months ago… it’s something related to tasmota “i can’t remember” which component implementation and something kasa is broadcasting over the network to detect new appliances.
