Trying to get -set dps output

You need to use a dash before the set -set So

node njstuya.js -ip <deviceip> -id <deviceid> -key <devicekey> -set "{ \"dps\": 1, \"set\": true }"
node njstuya.js -ip <deviceip> -id <deviceid> -key <devicekey> -set "{ \"dps\": 1, \"set\": false }"

Thank you! I overlooked this in my comment, as stated this was already working.

I'm particularly interested in the MQTT-end of this code. Do you know which device is sending the final MQTT command to my device or where I can find this code? By using this wrapper I can connect to it and control it. On the other hand, sorry for bothering you with this question, I know this might not be the best place for it..

I think you are on the wrong git page. I think you might want https://github.com/TheAgentK/tuya-mqtt

I haven't run tuya-mqtt before and it's too much effort to set up, but I did have a quick look at the code and made some changes. I'm not too hot on mqtt so I may be wrong but it doesn't look like you can send dps directly using that code. I made some minor changes so it might work but I haven't tested it. So try using my modified tuya-mqtt file. It's just a couple of functions if you want to add them to your existing setup.

So there already are functions to publish the data, I added a couple that receive messages that should send the dps commands to your device. So I used a similar format as they are published. But it's not exactly, I don't know if that means it won't wok.
I added two topic or whatever, dps and dpsJ. The J means that the DPSCOMMAND goes through a JSON.parse before being sent on.

 type + "/" + tuyaID + "/" + tuyaKey + "/" + tuyaIP + "/" +dps +"/" +DPSCOMMAND"
So something like this 
socket/32kdjtuyaIDsdfdf/3dfxtuyaKey/123.123.1.0.1/dps/"{ \"dps\": 1, \"set\": true }"

socket/32kdjtuyaIDsdfdf/3dfxtuyaKey/123.123.1.0.1/dpsJ/"{ \"dps\": 1, \"set\": true }"
