multiple module instances overwrites itself values

[BenRoe]

Ok other question.
If i setup a module twice in the config, do they share the variables from the code?

[DazDavid]

Any news here?

[BenRoe]

@DazDavid nope

Would it work if u give them names like MMM-FHEM1 and MMM-FHEM2?

Cause if u add two instances with the same name in the config i can imagine, that he will read the first value and overwrites them in the second instance. Like

var variable = 1;
var variable = 2;

Output would be 2.

@bobbob601 thx for the answer. Do you have a example how to write a module with multi-instace support?

Having the same problem with my module… A theoretical solution could be to make node_helper multi instance aware by appending some identifier to the notification unique to the instance: ie GET_WEATHER_001… The helper triggers on GET_WEATHER and builds an array with the different notifications and payloads. It then periodically runs through the array getting the appropriate requests and sending out notifications like WEATHER_001 with the specific payload.

Haven’t built it yet though…

@bobbob601 I got it working by passing a unique ID to the node helper and passing it back from the node helper.

Hope this helps.
