Emontx3 - changing wifi

[BerkshireBugsy (Dave Bareham)]

Hi all - I have an emontx3 (with wifi) which is connected to an old wireless network we used previously in the house which I’m trying to decommission. The last device I need to move off of it is the emontx3 but I can’t find out how to switch this to the new SSID. Changing the new ISPs wifi to the old name is not an option

I can ping the device on the “old” network but can’t browse to it to get to a UI - should I be able to?

I have seached but can’t find out how to change the wifi settings. Is this a case of treating it as if it was a new device and changing jumper settings.

Any guidance gratefully received.

Dave

I posted this a few years ago - got a ‘Like’ so it looks as if it worked.

Configure EmonTx on 1Phase after 3Phase set

Try this. It came from a thread about the emonEVSE, which I think also uses the ESP8266: “To reset the WiFi module to disconnect it from you local network and put it into AP mode again hold down boot / GPIO0 button on the ESP8266 module for about 5s will force WiFi access point mode.”

Failing this, or following on from, have you found this, and does it help?

If none of these help, I think it’s one for Trystan.

It should be possible to access the UI, are you trying on IP address 192.168.4.1? That would be the best approach and to then do a factory reset before starting again with configuring the new WiFi network.

A big thank you to everyone who replied. Further investigation revealed that the IP address I thought was the Emontx3 wasn’t - the clue was when I started a ping going and it continued to respond even when I killed the power to the emontx so sorry for wasting your time!
