Has anyone tested these devices?

Are these devices approachable by pimatic?
Thanks Hans

Its a tuya device. Flash it with tasmota and use it as MQTT device or help to develop a native plugin for tuya devices: https://forum.pimatic.org/topic/4390/plugin-driver-for-teepao-socket-tuya-api

Is there a manual how to flash?

At first you need to check wether it is really supported. You need to know which SoC is used.

A How-To for flashing tasmota should be found by Google.

See https://github.com/arendst/Sonoff-Tasmota

ESPurna will be an option.

I’d tried Tasmota and don’t like it. Alexa support is only via payments accessible…

ESPurna its free.

@Swen tasmota is also providing a free amazon alexa option based on the following emulation options:

• Belkin WeMo single device
• Hue Bridge multi device

I get only the information on website that you need Yeti for use. I installed Tasmota on Sonoff Basic and didn’t find an option for Alexa.
