Can Cerbo GX activate wifi switch on same network?

I want to trigger a wifi switch to activate a transfer valve when my tank level gets down to 10% and deactivate at 90%

depends on the wifi switch. Node-red running on the GX should be able to do that with a little bit of programming.

I use Sonoff wifi switches

I flash my Sonoffs with Tasmota, and then use MQTT messages from Node-Red on my Venus to switch them on or off.

There are quite a few existing topics on this subject here and in the archive, may be worth some googling.
