Hey, which type of ESP8266 are you using?

I've definitely used more than 3 before, but will test again in the next couple of days

[dr-apple]

I'm using a wemos d1 mini

[BlackyS]

@dr-apple: did you find a solution for you problem? I'm facing the same issue? (Could it be a heap issue in the code? Br Martin

[samazw]

Could you please provide your coding? My crystal ball does not show it to analyse your problem ;-) Do you also declare GPIO´s in your sketch? Or does it crash even without declaring GPIOs?

Hi Sascha, Sure - this make sense ;) I just thought that this problem could be some sort of a general issue ... and I think I solved it myself in the meantime ;) I used this code together with some other ressource hungry code (WIFIManger, WifiClientSecure und ESPAsyncTCP, MQTT Lib...) ... and I finally noticed that it has something to do with running low on heap memory ... 3 Switches were ok, but the 4th switch just hit the limit.... By using the latest builds of ESP Bordmanager (Arduino IDE) + updated all used Lib's + removed all debugging stuff - I noticed that I have some heap memory left und my code runs now smoothly with 4 switches (and that's all I need). So thank you for your help! BR Martin

WiFi client secure uses 20k of heap I'm pretty sure so it definitely limits what else you can do on a board
