Thanks - it worked for me like that:

19:59:47 CMD: rule 1 19:59:47 SRC: WebConsole from 192.168.0.166 19:59:47 RSL: Group 0, Index 1, Command RULE, Data 1 19:59:47 MQT: stat/sonoff/RESULT = {"Rule1":"ON","Once":"OFF","StopOnError":"OFF","Free":436,"Rules":"on power1#state=1 do publish stat/sonoff/TIME {"Time":"%timestamp%"} endon "} 20:01:02 HTP: Main Menu 20:01:05 HTP: Console 20:01:08 HTP: Main Menu 20:01:10 SRC: WebGui from 192.168.0.166 20:01:10 MQT: stat/sonoff/RESULT = {"POWER":"ON"} 20:01:10 MQT: stat/sonoff/POWER = ON 20:01:10 RUL: POWER1#STATE=1 performs "publish stat/sonoff/TIME {"Time":"2019-04-15T20:01:10"}" 20:01:10 SRC: Rule 20:01:10 RSL: Group 0, Index 1, Command PUBLISH, Data stat/sonoff/TIME {"Time":"2019-04-15T20:01:10"} 20:01:10 MQT: stat/sonoff/TIME = {"Time":"2019-04-15T20:01:10"}

Mosquitto is doing fine too:

Client mosqsub|13000-raspberry received PUBLISH (d0, q0, r0, m0, 'stat/sonoff/POWER', ... (2 bytes)) stat/sonoff/POWER ON Client mosqsub|13000-raspberry received PUBLISH (d0, q0, r0, m0, 'stat/sonoff/TIME', ... (30 bytes)) stat/sonoff/TIME {"Time":"2019-04-15T20:01:10"}

the only issue for now is that it’s ‘One-Shot’ even if it says it’s not (“Once”:“OFF”)
