MQTT import ??

[Asco]

Hello,
I would like to use the plugin "MQTT import" on a ESPeasy_01 module to get sensor values from another ESPeasy_02 device.

I have read a lot of post about this but can't understand how to use the plugin, perhaps someone can help me please ?

using red-node debug I can get:

Code: Select all

23/09/2018 à 12:01:33node: bf8fd352.782658domoticz/in : msg.payload : string[57]
"{"idx":225,"RSSI":10,"nvalue":0,"svalue":"21.30;58.40;1"}"

This is from a ESPeasy_01 who send DHT22 reading to a Domoticz server, it can correctly get the 2 values in Domoticz

How can I get thoses datas in the second ESPeasy, does using the pluggin MQTT import the good way to do that?

Thank you in advance!!

MQTT import is simple so you cannot use JSON formatted messages, only a single float value is supported.

If I where you I'd use rules and push a simple messages on change of that first device. Then on the receiving unit I'd just subscribe to the topic.

Hello grovkillen,
Thank you for your help,

As you can understand I'm very new to MQTT

I don't understand what you mean by "push a simple message" and I don't understand "subscribe to the topic"

... SO I think I have to read more about espeasy before coming back to ask a question.

Regards

Hello,

I have been able to write rules to publish from ESP_02 the 2 datas I need to read on the other ESP:

Code: Select all

chris@L750D:~$ mosquitto_sub -h 192.168.1.3 -t ESP_02_BALANCE/#
"poidsLili":2.20
"poidsMiha":3.10

On the ESP which has to receive the datas I have set a controller:

Capturecontroller.PNG

and a device:

Capturedevice.PNG

But I can't get poidsMiha and poidsLili on the second ESP.

Can you help me with this?

Thank you in advance!

MQTT Import is kinda its own client. You will set the subscription inside the task settings, not the controller settings.

Thank you grovkillen,

is there an example somewhere, I am able to use MQTT with node-red, domoticz and mosquitto, but can't understand how it works with ESPeasy ?

I think there is something wrong with phpBB ;impossible to put 2 images inline..

Regarding attached pictures, you should just upload them and the forum will place then in the end.

I will need to put some love to the wiki regarding MQTT import. I'll give you a holler once it's done.
