…ter initial wifi configuration. This makes it easier for initial configuration and allow much higher customisation afterwards, MQTT isn't mandatory now and can be disabled, physical switch, faxmo can be enabled and setup withing this configuration portal too. HTTP API is now always on, as it is using same webserver as config portal. I may add some settings for HTTP API later on with possibility to disable it, except for configuration portal. Notable change is that now you can reset your device to factory settings from this configuration portal. Detection/relay test feature was added to the initial wifi config portal, so you can detect by turning relay ON/OFF what module are you connected to. Alexa implementation is still in beta and may not work on Gen2 devices.
