DDD from Shelly Flood does not work

  • I am trying to send DDD from a Shelly Flood Sensor to a ShellyPlug, but the ShellyPlug does not switch as expected

    Shelly Flood sensor:

    IP: 192.168.0.191

    Command configured when rain is detected: http://192.168.0.179/relay/0?turn=on

    Firmware: 20211109-125548/v1.11.7-g682a0db

    Shelly plug

    IP: 192.168.0.179

    Firmware: 20211109-130223/v1.11.7-g682a0db

    My test PC connects to both devices, the state of the plug changes when DDD is sent from browser but not when sent from the sensor. The sensor detects water and can control relays via a scene on Shelly Cloud.

    When setting a DDD action on the sensor via Shelly Cloud the configuration change is confirmed but when going back to the same page the configuration has been lost.

    There is an old post with similar problem solved by upgrading to v1.9.1. Has the issue returned? Does the clould actually change the setting? Does the sensor actually send any DDD?
