Node-Red Battery temperatures

I currently sense two battery temperatures using Wemos D1 Mini and send the data over MQTT.

Is it possible for Node-Red (large-image running on the Rpi) to write these temperatures to the GX part as Battery Temp 1 and Battery Temp 2 instead of using and ADC?

Node-Red can read from a temperature sensor (there is a node for that) but can it write values?

Thanks.

Hi. Indeed not possible at the moment. It was discussed, and for sure would be cool; but needs someone to go and develop that

I use OpenHab to integrate and controll my Victron setup over Mqtt, also other sensors on ESP32 board over Mqtt. Nice GUI in HABpanel. Lots of possibilities to create rules and calculate virtual parameters/items to do anyting you want ;-) !
