This power socket switch by Delock can be controlled via button or WLAN. With the installed Tasmota firmware, the switch can be easily integrated into existing systems for home automation, IoT or M2M. With the help of the web interface, the power socket can be controlled without having to rely on the cloud or an app.

What is the user name for the web interface if a password has been assigned? The default user name is "admin".
It is not possible to enter a WLAN password with an asterisk (*). The problem is solved with the current firmware version 6.5.0 since 22.10.19.
How to flash the device to the latest Tasmota version? For the socket switch we use a version of Tasmota, that we have adjusted and tested. Please understand that we can only support this Tasmota version.
What are the changes in firmware 6.7.1 since 6.3.20? • Fix WeMo emulation for 1G echo and 2G echo dot.
• Add command "time" to disable NTP and set UTC time
• Removed support for WPS.  
What are the changes in firmware 7.2? • Change default GUI to dark theme
• New Arduino Core version
• The LED is now controlled in the same way as Tasmota
• For the hardware configuration a user template is now used.
We recommend you save the device settings and do a "Reset 6" as console command. This will restore the default settings, but keep the WIFI SSID and Password.
Weaker Wi-Fi signal after firmware upgrade The Wi-Fi calibration needs to be deleted to force the device to re-calibrate Wi-Fi after it restarts.
1. Run "reset 3" in the Console (your existing settings will not be affected).
2. The device will restart
3. Cycle the power on the device (unplug and plug it).
Wi-Fi calibration will not be done unless the device performs a cold boot from power up.
Configuration options In case of problems, the following switches can help:
SetOption55 mDNS service 0 = disable 1 = enable
SetOption19 Set Home Assistant discovery protocol 0 = use Tasmota integration (default) 1 = use MQTT discovery
SetOption109 0 = (default) 1 = force gen1 Alexa mode, for Echo Dot 2nd gen devices only
The device does not connect to the Wi-Fi If your device does not connect to your Wi-Fi and you've made sure the Wi-Fi credentials are correct, it is caused by using special chars or white spaces in your SSID or Password of your Wi-Fi. Remove them and try again. Other reason can be using an SSID longer than the allowed 32 characters.
