Sonoff 4Ch R2 Pro - wifi problem

ESPHome
1

Have a Sonoff 4Ch R2 Pro and can flash it per instructions on my house wifi ssid “Web-Cube”.

Once I have it up an running / configured, I need to move it to my shed which has a different ssid “WebCube”.

I change the ssid of the config yaml and use the OTA Esphome dashboard to upload and change the ssid for the sonoff. However this will not work despite having done a similar procedure with an ESP32.

Is it possible to change the ssid of a sonoff (ESP8266) via OTA?

sonoff.yaml

I run into this when replacing my router, maybe it’ll work for you.

I had to reconnect my old router and add BOTH SSIDs for the old and new routers. See here under Connecting to Multiple Networks

Then I uploaded with old router, swapped to new router and it connected.
Then edit the YAML and remove the old SSID (not really necessary).

If I’d known about this in advance, I would have added both SSIDs before removing old router

Give this a try - Add both SSIDs and passwords and it will connect to either, once connected to new one, remove the old SSID so it won’t connect to it.

  networks:
  - ssid: Web-Cube
    password: pass123
  - ssid: WebCube
    password: pass123

Thanks, will try that!

Wasn’t the solution but a very useful config where you have multiple ssids

Turns out it was the DD-WRT firmware running on an old Asus router.
Needed to disable WMM in the router, reboot and it connected.
Some background.

An ESP32 connected ok but the Sonoff ESP8266 did not like WMM.

Thanks again.
