Ethernet and WiFi

The e.station has both a network socket and the option of a Wi-Fi connection. For reliable 24/7 operation, we recommend a wired network connection using an Ethernet cable.

Step 1: Open the e.station interface

In its factory settings, the Ethernet interface of the e.station is preconfigured for "DHCP".
If your router is also set to "DHCP", the e.station will automatically receive an IP address. You can open the e.station via http://<>-eth 
(provided your router supports this function). 
Otherwise, check in your router or use an IP scanner (e.g. "Angry-IP") to find out which IP address the e.station has been assigned.
When you open the e.station in your browser via its IP address or serial number, the main page of the e.station appears.

If the DHCP box is ticked, the manual network parameters are hidden in the Tasmota firmware of the e.station.

Step 2: Open the network settings of the e.station.

Click "Configuration -> Ethernet".
By default, the DHCP box is ticked and the router assigns the IP address. 
If you want to assign a static IP address, untick the box and enter the required network parameters manually. 
After saving, the e.station restarts and can be reached via the new IP address.

 

WiFi setup

Requirements

  • Device with Tasmota firmware installed
  • Smartphone or PC with Wi-Fi
  • Access credentials for your home network (SSID and password)

Step 1: Connect to the e.station access point

On first start-up (or if no Wi-Fi is configured), Tasmota automatically opens its own Wi-Fi access point.

  • SSID: <>
  • Password: (none – open network)

Connect to this network using your smartphone or PC.

Step 2: Open the configuration page

Once connected, a captive portal window opens automatically in many cases. If it does not, open your browser manually and go to the following address:

 
 
http://192.168.4.1

The Tasmota configuration page is displayed.

Step 3: Configure Wi-Fi

Click "Configure WiFi".

Step 4: Select the network and enter the password

On the Wi-Fi configuration page, you will see a list of available networks.

  1. Select your home network (SSID) from the list – or type the name manually into the "AP1 SSId" field.
  2. Enter your Wi-Fi password in the "AP1 Password" field.
  3. Optional: You can enter a second network under AP2 as a fallback.

  4. Click "Save".

    Tasmota saves the credentials and restarts. The device disconnects from its own access point and connects to your home network.

Step 6: Find the IP address

After the restart, the device can be reached in your home network. You can find the assigned IP address:

  • In the router interface (e.g. FRITZ!Box → Home Network → Network)
  • Using a network scanner (e.g. the "Fing" or "AngryIP" app)
  • In the serial console, if the device is connected via USB

Step 7: Open the Tasmota web interface

Open your browser and enter the IP address you found, e.g.:

http://192.168.1.42

The Tasmota main interface appears – the Wi-Fi setup is complete.

Once the network setup of the e.station is complete, you should check the MQTT settings and adjust them if necessary.
You also need to set the pulse rate of the electricity, water or gas meters.

Common problems

Problem Solution
Access point XXXXXX does not appear Switch the device off and on again; perform a reset if necessary
Connection to the access point fails Use a different Wi-Fi client (e.g. mobile phone instead of PC)
Device does not connect to the home network Check SSID and password; avoid special characters in the password
IP address unknown Check the router's DHCP list or use a network scanner
Web interface not reachable Make sure you are on the same network as the device

 

Resetting the e.station to factory settings (AP mode)

  1. Switch the e.station on and off 6 times briefly (approx. 1–2 seconds each) – Tasmota counts each boot.
  2. Do NOT disconnect the power on the 7th power-up – Tasmota now resets the Wi-Fi configuration and starts in AP mode.
  3. After a few seconds, the Wi-Fi network "Tasmota??????" appears.
  4. Connect to this network and then reconfigure the e.station with the required Wi-Fi parameters.

Note: A boot is triggered by applying the supply voltage – not by pressing the reset button.

 

Tip: assign a host name

Under Configuration → Configure Other, you can assign a host name to the device (e.g. tasmota-e.station-verbrauch). It can then be reached at http://tasmota-steckdose-kueche.local without you needing to know the IP address.
