Wi-Fi connectivity issues on a Chinese ESPHome based relay device

[tomicloud]

Hi there,

I bought a 4-channel relay panel from AliExpress. I was able to install an ESPHome firmware on it without any issues, and it basicly works, but its stability is very poor.
I have another devices running ESPHome firmware (like this), and all of them are completely stable.

The main stability issue is that the device disconnects from my WiFi every few minutes or sometimes a few hours - and due to the API disconnection, it reboots itself. After rebooting, it is able to reconnect to my WiFi again. The access point is in the same room as the device. The reported wifi signal sthrength is around -50dBm.

My first thought was that the problem migbt be insufufficient power: my PC might not be able to provice enought current to the device throught the USB-C cable. Because of this, I powered it using a smartphone charger together with a PD trigger board (12V) connected ti its DC input. At the same time I kept the device connected to my PC so I could read the log via the serial connection.

Some more info:

• ESP module on the relay panel: DOIT ESP32-32E N4
• Sometimes I cannot update it’s firmware via OTA, but I believe this is related to the issue described above.
• I wrote a test Home Assistant script in which I rapidly switch a relay on and off. In some positions (possibly blocking the antenna), the switching commands are missed, and then a large number of buffered switch commands are executed very rapidly afterward.

At this point, I’m trying to determine whether the issue is caused by hardware instability, power supply problems, or a software/ESPHome configuration issue. Any suggestions on what else I sould check or how I could further debug this problem would be greatly appreciated.

Thank you,
tom

In my Home Assistant the uptime chart looks like this, and the device info is here:

ESPHome - Wifi - Auth Expired

Hi, I’ve read all the post on this forum relating to this error but none of the suggested solutions work for me. Basically my Wemos D1, using ESP Home on one particular unit is not connecting to WiFi. I have changed the Wemos and the result is the same so I assume it’s something in my configuration but I can’t figure out what. Could someone suggest how to get around this? The error [image] And the ESP Configuration: esphome: name: kitchen_display platform: ESP8266 board: d1_mini_pro …

[Neil_Brownlee]

Ok, I had an issue a bit like this - my CPU was too busy on the ESP device.

[tmjpugh]

Why arduino and not esp-idf? Try with esp-idf?

Test without web server?

I would actual test without any component and just WiFi config and logging.

[Neil_Brownlee]

Also what does the contents of this sensor say?

text_sensor:
  - platform: debug
    device:
      name: "Device Info"
    reset_reason:
      name: "Reset Reason"

[Neil_Brownlee]

@tomicloud

Sometimes I cannot update it’s firmware via OTA, but I believe this is related to the issue described above.

This is a classic case of the device being too busy and blocking the WiFi loop.

[Neil_Brownlee]

Remove these

  enable_btm: True
  enable_rrm: True

Add

fast_connect: true

[IOT7712]

Are all your varied power supply ground connectors connected? No switching power supply noise issues?

Do you have a static IP Address allocated to your device from the router?

[tomicloud]

I tried several changes, but by themselves they didn’t solve the issue:

• Replaced the framework type with esp-idf
• Removed WebUI and Captive Portal
• Removed Modbus UART
• Removed WiFi btm and rrm
• Added fast_connect
• Added electrolytic capacitors to VIN, 5V, 3V3

Despite these changes, the problem was still present.

However, the following modification worked for me. After changing the WiFi configuration, the device became stable and has now been running for about 16 hours without any issues:

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  power_save_mode: NONE
  output_power: 8.5

It seems that, in my case, the WiFi output power settings were the key to achieving stability.
Can someone explain to me why this solved the problem?

[Neil_Brownlee]

I did suggest you remove the meshing options - I’d say it was that rather than the power setting.

[tomicloud]

Sorry, I forgot to mention that based on your recommendation I removed BTM and RRM (edited). However, it was not stable without output_power settings.
With fast connect and without output power limit it was not stable.
