Tasmota: Sonoff 4CH Pro turning off other relays after turning 1 on

[pascallieverse]

Hello,

When I want to turn on a channel on my Sonoff 4CH Pro it automatically turn’s off the other channels. I just don’t get it to work with more than one channel turned on. I have used the web interface and MQTT to send those commends.

The log I am getting is:

18:27:08 MQT: stat/pro/RESULT = {"POWER1":"ON"}
18:27:08 MQT: stat/pro/POWER1 = ON
18:27:11 MQT: stat/pro/RESULT = {"POWER2":"ON"}
18:27:11 MQT: stat/pro/POWER2 = ON
18:27:11 MQT: stat/pro/RESULT = {"POWER1":"OFF"}
18:27:11 MQT: stat/pro/POWER1 = OFF

Is it that the 4CH Pro can only handle 1 channel powered on with Tasmota?

the Pro has an "interlocking" function, but you can change it to "self-locking":
