ESP8266 Huzzah WIFI module - Change WiFi Network

[DickiePhitt (Gordon Smith)]

Hi,

I’ve had no problems for a couple of years using a emonTx V3 with Huzzah wifi adaptor.

Having upgraded my network I need to change the network to which the Huzzah WiFi module is connected.

As expected the Huzzah goes into AP mode, having lost its linked wifi network, however when I connect to 192.169.4.1 it is asking for a username & password.
I’m pretty sure I didn’t originally input one and if I did it would have been identical to my OpenEnergyMonitor details.
Anyway I cannot access the Huzzah to change the wifi network.
I’m aware of an option to power up with a reset button pressed, but would like to have checked out the options to go through the front door before breaking the front door down, so to speak!

Thanks for any advice

Is there anything to prevent you from giving the “new” network the same SSID as the old? If you can, all your devices will seamlessly connect to the replacement.

Failing that, I think a similar question was asked fairly recently. Try these:

How to change an emonTx (with ESP8266) IP address

The instructions for setting up the EmonTx with the ESP wifi module are here: Reading through that, it looks like the IP address of the EmonTx WiFi module is not important to the configuration of the Emon system, as long as it can communicate with the EmonCMS endpoint (your EmonPi). To change the WiFi network they are connected to, you need to connect to each one individually and change the WiFi settings (as per the guide above). You should be able to use your current DHCP table from your rou…

ESP8266 Connection Issue

Hi, Just received an ESP8266 to plug into a EmonTxV3. So, I started the process, did everything, jumper, USB and AC power etc. Got started and joined the Wifi AP and was presented with the screen to configure the connection to the normal Wifi as expected. Half way through keying the password, the phone disconnected from the AP. Turns out I hadn’t fully pushed in the USB cable and therefore the ESP8266 lost power. Restarted the process, but now I’m not getting any AP advertised when I start…

ESP 8266 Huzzah Problem

I have 3 such modules and have successfully flashed them all with emonESP-master a couple of weeks ago. Two modules have been working since then in my test rig. I’ve just tried to hook up the third module but have a problem – I can browse to its IP address but am asked for a username & password which I can’t recall. The default username/password does not work. I tried putting it in AP mode but could not connect to 192.168.4.1. I re-flashed with emonESP-master but still the same problem. An…

Thanks for getting back to me so quickly. It’s a bit late for leaving the SSID as it was because everything else is reconfigured. Advance reading intimated the EmonTx should be easily changed.

Thanks too for pointing me at the earlier posts. I’d seen them, albeit after the event, and am frantically avoiding having to get bogged down in reflashing.

I’ll set up a temporary network with the old credentials and see if I can access the Huzzah. Failing a resolution I reckon it’s easier just to buy a new one!

Thanks again.

Before you do that, let’s see if the real networking experts are able to help you.

I’ve never owned an ESP8266, so I can only refer you to what’s been seen here before.

Most of the current network wireless devices can handle multiple SSID’s. So, create the old SSID. A smartphone can also easy setup a hotspot with same settings as your network before… many ways to create the ‘old’ environment.

[DickiePhitt (Gordon Smith)]

Yes, tried that both with phone and router but in both cases the module asks for Username and Password.
Am returning unit to get reflash rather than mess about any further.
Thank you for your input.
