I found myself asking the very same question a few weeks ago.
It is possible to set the ‘Manual mode’ setpoint using the latest node-red-contrib-ewelink-cube node v1.2.1, but not the auto mode setpoint. My solution is also really quite clunky as it is not possible to send a setpoint value, instead i used a switch node with integer inputs.
Can you share your flow?
Thank
I’ve done it, but this way is crazy. You should be able to send the number directly

I agree mate.
In the end I chose to use the iHost to set the Time/Temp profiles in Auto mode and with the help of some Node-RED code from psavie, switch the boiler on/off.
The last bit was setting all the Sonoff TRVs back to AUTO every hour.
