The pre-flashed TASMOTA devices provided by Martin Jerry are based on ESP chips (ESP8266 or ESP8258).
1. Both of these wifi chips only support 2.4G WiFi;
2. We set WifiConfig 2 as Wi-Fi Manager, thus the devices will enter pairing mode automatically if there is no previously paired wifi router around.
3. We already set well the gpio definition inside the pre-installed firmware, thus the device must work well manually after correct installation/wiring.
Step 1: On your smartphone, connect a hotspot like "tasmota_xxx", created by the device.
Step 2: After Step 1, it will go to the tasmota wifi connection page HTTP://192.168.4.1, and you should select the 2.4G ssid and input the correct password for pairing.
Step 3: Once it links the wifi router successfully, it will show the IP address of this device and go to this page directly.[in some cases, the device IP address cannot display correctly but you cannot find the hotspot like "tasmota-xxx" anymore to pair it again. You can go to the router setting page, like 192.168.0.1, and find the device's correct IP address.]
Step 4: You can access the device via its IP address. When you see the page like below, the device is connected successfully.
