Hi to all!
Can you explaine me how to set values for Dummy Switch with mqtt command?
I have this config on my esp:

This command:

Code: Select all

mosquitto_pub -h xxx.xxx.xxx.xxx -t "sonoff_esp/Boot_State/OnBoot_On" -m 1

don't do anything for esp dummy switch (

You need to use this topic:

Code: Select all

sonoff_esp/cmd

And this payload:

Code: Select all

TaskValueSet,2,1,1

Edit: if TaskValueSet isn't accessible through mqtt then you'll need to create an event.

Please refer to the wiki.

Thanks.
Now all works with http request. With mqtt no lucky.

Now that's not good. What's your setup for MQTT?

[tribal]

MQTT setup in ESP or in MQTT broker server?

PS dummy switches don't save values after reboot.. all switches have "0". That's not what I respect
I try to make an external control for boot state of relay after reboot. Maybe I do something wrong?

[grovkillen]

Controller setup in esp.

Regarding losing values on reboot, every device does this. We would need to add support for a EEPROM module or other backup memory.

This is my setup:

In advanced settings:
MQTT Retain Msg: on
Message Delay: 1000 [ms]

If all states are lost, how to save values for preferred boot state?
The modules has many free space, why it don't save any values on it? This not logical and uncomfortable.

Due to a limited life time of the flash chips, we reduce all write cycles to a minimum.

[grovkillen]

Yes that is the reason for not using the main flash for storing values. It's completely logical and how it should work.

Until we have support for external EEPROM (not sure if we will add it), you can use retained messages since the broker will always store these and then they'll be re-imported on boot.

Or you could make a rule that set the trask values on system#boot

how can I do it?
for now it don't get retained messages. Maybe it depends from espeasy software?
in mosquito I activate retained messages.

Under the advance page. If you study the wiki you will find info like this.

[tribal]

In advanced settings:
MQTT Retain Msg: on
Message Delay: 1000 [ms]

I do it when flash the device. But nothing changed. If it will works for me, I don't ask how to do this!

[grovkillen]

So then you need to make sure that the dummy is reporting to the broker. Once every minute or so? Then you need mqtt import to get them back from the broker. But if this is over you knowledge I will make a guide for others to follow, don't have the time right now but soon.

[tribal]

I understand the logic, but I don't understand why it doesn't work in my case!
Maybe it's because I have GIT version: mega-20180104 ?

I will make a guide for others to follow, don't have the time right now but soon.

It will be greate. Don't rush you, It's not urgently.

Upd. the retain for gpio pins now working (in openhab config was disabled retain policy)
But I still can't change the values of dummy switch with mqtt!
