When ESP8266 reboots, the Duco goes to High Fan RPM

[Jozziej]

Is there a way to make sure that when the ESP8266 reboots, the Duco does not go to High? Simply I always have the Duco at Permanent Low, which is changed to 20% in the Duco box itself.

After reboot it is assumed that the fan is running in automatic mode. https://github.com/arnemauer/Ducobox-ESPEasy-Plugin/blob/master/_P150_DucoRFGateway.ino#L21

After initialising the CC1101 chip the gateway will send a subscribe message to the Ducobox to get the current ventilation mode.

For some reason the ventilation does go to High every time the esp8266 lost connection or did a reboot. Is there a way to force a certain ventilation value, like permanent low?

Do you use mqtt? Could you try to disable that controller and reboot? Is de ducobox still changing ventilation mode to high after a reboot?

[Jozziej]

Yes I use MQTT to Home Assistant, when I disable the MQTT controller and reboot the ESP, the Duco box does not change the Fan to High. As soon as I enable the Mqtt controller again, instand change to Fan High.

It is not the plugin changing the ventilationmode. If you open the mqtt controller configuration page, do you have the retain checkbox on?

[Jozziej]

Yes

[arnemauer]

Uncheck it...

[Jozziej]

Tried that, and makes no difference

Hi Arne you can close this issue. For some reason the Mqtt broker retained the Ventilation High cmd. Solved that.
