Error: XiaomiGateway: unable to write command - Invalid key

Post by aray »

Hi there.

I've recently created a simple web page where I call domoticz API to control my Xiaomi smart home. The domoticz server runs on a raspberry pi and the smart home configuration consists of xiaomi getaway, YeeLight bulbs and a couple of temperature sensors.

It has been working perfectly about two weeks, but then the connection to getaway became unstable. The Temp + Humidity + Baro sensor stopped to push its values and Toggle command starts randomly returning the "Error sending switch command". Besides, when there are no errors, the light sometimes does not turn on.

Here is the log:
Spoiler: show

Code: Select all

Raspberry OS: 10 (buster)

The problem was solved by disabling power management on my raspberry:

Code: Select all

sudo iwconfig wlan0 power off
