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 220.127.116.11 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!
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.
