ESPeasy 2.0 MQTT Broadcast

[nigelbe]

Hello,

I just discovered ESPeasy and it is wonderful: But there is one thing missing and that is the ability to subscribe to any random MQTT topic that does NOT use %sysname%.

I already have quite a few Wemos D1 Mini devices around my home, each one using software I developed myself. All these subscribe to "LED" and each returns a ACK to the controller.
I use the payload (ON or OFF) to turn the BUILTIN_LED on or off. The ACKs allow me to see that the device is alive. Alternating commands are sent every 30 seconds from my home automation.

My home automation is "Premise SYS" http://cocoontech.com/forums/forum/51-p ... e-control/ which is 20 years old, Free, but not open source.

MQTT Import is the answer... You can import any topic. To publish any topic you should use rules. More is found on the wiki:

Hello,

I have looked at MQTT but I don't understand it. So I tried this:

and I ended up with this:

What's all the 4 values about and why ADC(TOUT)?

I am bemused by it all.

The MQTT Import plugin work as such:

You can have up to 4 imported values per device/task. This doesn't mean that you HAVE to use them all.

The name is the name you use in rules etc. internally within ESP Easy.
MQTT Topic 1-4 is the topics you want to listen to, one per imported value.
Value Name 1-4 is the name of the VALUE that you use internally within ESP Easy.
In general you wont need to use formula, and if no formula is needed you do not need to add any information to that box. So %value% is not necessary.

You may use the MQTT Import together with Rules as this:

For the rules you could use the imported value as such:

Code: Select all

on sniff#cmdMQTT=1 do
  Publish %sysname%/IP,%ip%
endon

on sniff#cmdMQTT=2 do
  Publish %sysname%/Time,%systime%
endon

on sniff#cmdMQTT=3 do
 Publish %sysname%/status,Rebooting
 Reboot
endon

I hope this gives you an idea of how to use the MQTT Import plugin.

Further to this:

I see IMPT : BAD Import MQTT Command LED in the Log
also IMPT : Illegal Payload OFF LED

You should not give both the task and the value same name. You call the task/device LED, and the value LED. You should use something like "sniff" (I personally like to call the MQTT Importer , a sniffer), and then I generally use the same value name as the topic that I'm sniffing for .

I hope this gives you an idea of how to use the MQTT Import plugin.

I don't have the OPTIONAL section of LED import

Which build should I be using?

[grovkillen]

Also forgot. As of now ONLY NUMBERS are allowed to be imported. Thus my use of only integer.

I've use this both for R147 and the new 2.0.0-devXX versions. No problem what so ever. Your problem is probably the use of non-integer payload (message content of MQTT topic LED should be 0 and not OFF).

I made a wikipage for this plugin: https://www.letscontrolit.com/wiki/inde ... QTT_Import

More information will probably follow...

Thanks a lot

[nigelbe]

Thanks a lot, I got it working just by changing to another topic name and numeric payload as you suggested.

I've tried to compile it but I'm in Library Hell

You got official test versions here:

Thanks grovkillen, that's the binary I'm using.
