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.

Monitoring energy consumption
At a glance, the current energy consumption at the socket can be determined. This allows energy efficiency and cost to be assessed, and unusual operating conditions can be detected.

What is the user name for the web interface if a password has been assigned? The default user name is "admin".
The energy monitoring is not accurate. Due to component tolerances and manufacturing, the device allows only an approximate measurement of the power. If necessary, e.g. after a reset, it is possible to obtain a better result by calibration:
Alternatively you can use a rough estimate with following console commands: CurrentCal 3300, PowerCal 10000, VoltageCal 1650.
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? • 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.
