Using variable %topic% in berry script

[waltkind]

Hi, I want to generalize a rule I have in all my tasmota devices.
There I have a rule:

def mqan()
  import mqtt
  mqtt.publish('tasmota/az-touch_1/LWT','Online')
  mqtt.publish('tasmota/az-touch_1/ip', tasmota.wifi('ip'))
end
tasmota.add_rule("MQTT#Connected=1", mqan)

I would like to change the specific devicename with %topic% to have the same code for all devices.
When I replace 'az-touch_1' with '%topic%' it is published as %topic% but not replaced by the topic of the device.
I tried many variations with brackets and quotes, but no success.

Rule variables are indeed not a part of the Berry Tasmota integration. You can access many values via commands, like this:

var topic = tasmota.cmd('Topic')['Topic']
mqtt.publish(f'tasmota/{topic}/LWT','Online')

That's done the trick.
Thank you very much. I didn't find this in all my search.
