I can't read the dps

[screenreaders]

Hello, I bought a multi plug.
http://www.aliexpress.com/item/WiFi-Smart-Power-Strip-EU-Plug-Surge-Protector-6-Socket-with-USB-Port-Remote-Control-Switch/32931245092.html?spm= a2g0s.9042311.0.0.1ec65c0fLypEZr
I extracted the tuya.cli key.
I can't read the dps.
A prompt is displayed to try again.
I added 1 dps to the trial.
Nothing happens when the switch is pressed.
In Domoticz I have this error:
