I TWIST SO BAD: SWITCH SHELLY PLUS 2PM VIA MQTT AND NODERED

[faithl5x]

Hello together

I am currently learning MQTT and want to implement what I have learned together with NodeRed and Shellys.

Yesterday I finally managed to read out my Shelly Plus 2PM with AddON via MQTT.

But now I'm faced with a problem. I would also like to send switching commands via MQTT so that the Shelly logically also switches.
At the moment it looks like this:


I use the MQTT Explorer program for better debugging. There it looks like this:


The code of switch:1 looks like this ("output" toggles between true and false)

{"id":1, "source":"WS_in", "output":true, "apower":0.0, "voltage":232.8, "freq":49.9, "current":0.000, "pf":0.00, "aenergy":{"total":0.000,"by_minute":[0.000,0.000,0.000],"minute_ts":1708102380}, "ret_aenergy":{"total":0.000,"by_minute":[0.000,0.000,0.000],"minute_ts":1708102380},"temperature":{"tC":56.4, "tF":133.5}}

No matter what I do, I can't manage to switch the Shelly... 😞
What do I have to do so that I can switch the Shelly from NodeRed?

Thanks for your help.
