I have had a new sensor kit SDS011/BME280 sensor ID 5423193 for a few weeks
It is very annoying that this system fails regularly, i.e. it is not stable.
However, the WLAN connection remains active.
I have already exchanged the Node MCU ESP8266 and flashed it again, unfortunately without success.
What else can I do to make this system stable?
Just get a better USB 5V powersupply with at least 1.5A.
The symptoms are those a weak PSU.
Thank you for responding,
After connecting to USB 5V 3A power supply the same symptom… still not stable…
Is there the wps Option on the Router ?
Can you send me the serial log ? Plug a usb câble and read the serial with the arduino ide or screen in bash
Hello,
I just flashed the ESP8266 again and oplaced a node of the mesh wifi system near this.
I will try this first.
Router has a wps button.
This is the device status after flashing.

This looks normal. Can you get the following logs?
I placed a router mesh node near the ESP8266 and the problem seems to be solved.
The WiFi signal is now 100% and connection seems to be stable now.
Many thanks for your help.
Now something strange occurs. I can see my sensor on PM sensors - Grafana (madavi.de)
but I can’t login with my IP adres 192.168.1.10 (check IP adres on my router)
