MQTT and ioBroker

Hardware diyBMS
1

Hello,

Now my first controller and 7 Modules are running very well.
Unfortunately, I have a issue with MQTT and ioBroker. The values are not separated. I looks like a high number of values are only in one value. See attached pictures. I was searching in the web but not find a solution. Hope somebody could help me.

Thanks to Stuart for the nice project!

Thats correct - its a JSON payload

If you familiar with Blocky, just use this block.

It does the job for you

in case of future questions, feel free to ask.

Hi Chris,

yes, I made same blocky´s . Puh that means I have to separate all values by self. Please, do you have a part of a screen shot for me? That I could copy it.
Thanks. BR Tom

@stuart thanks for splitting this up :wink:

The question ist, why? What you going to do with all this values. if you only like to view them in your visualisation, just use the .json table. If you are using some of this values in calculation or else use the block above to receive the needed value.
At least, this would be the way I would do it.

Hi Chris,
I would like to sent notifications if something is happen.

I wrote a script this works well and could modified.
Only add the relevant objects in Biobroker

Hello,

please can someone post their IObroker and diyBMS MQTT settings here?
I’m doing something wrong :frowning:

Thanks, Frodo

Hi, which the important is, that you define the same Port, User and PW on both sides and define the IOBroker side as MQTT broker not slave.
Be aware, if you have also tasmota or something else (MQTT based) running you may have conflicts with the ports.
