ESPHome nodes randomly disconnecting from Asus 2.4Ghz band

ESPHome

Hi all,

I’ve been playing some time with HA and ESPHome and several ESP8266 (D1 Mini) nodes to monitor temperatures and Air Quality at home.

Since I moved and replaced my router with a brand new ASUS ZenWifi XT8 I have been experiencing random disconnections of the nodes from the network. It is very strange as they still appear online in the router settings and in the ESPHome dashboard but I can’t ping them nor receive values from them.

Firmware in Router, HA, ESPHome and nodes are all up to date. I tried modifying all the settings in the 2.4Ghz band to try to simplify the connection but it didn’t fix the issue. As soon as I reboot the router or the nodes, everything goes back to normal…

Any ideas?

Do you use static ip addresses for your nodes?

# Example configuration entry
wifi:
  ssid: MyHomeNetwork
  password: VerySafePassword

  # Optional manual IP
  manual_ip:
    static_ip: 192.168.0.123
    gateway: 192.168.0.1
    subnet: 255.255.255.0

I had the same problem with randomly disconnecting nodes (ESP8266 - ESP32 - …) on my ASUS ROG Rapture GT-AC5300

Reprogramming all nodes with static ip addresses completely solved the problems for me
