Are there any possibilites to see the internal Multiplus temperature of Mosfet/Transformer?
Using the dashboard V1, V2, VRM or any variables by NodeRed?
No there is not. A few people have however used the temp sensor that comes with it and attached it to the transformer.
In the photo I opened a 10k and a 5k Multiplus. There seems anything inside the torroid transformer like a NTC. Blue cable pair goes to controller pcb. Obviously this signal only reports a binary overtemperature alarm bit format not a temperature value.
The strong temperature derating of Multiplus is explained here why it would be usefull to read the value what the devices sees itself to estimate the usable output power. Possibly it could be realized by FW update ?
