Access light sensor from Touch 70

Node-RED

I’m building a campervan and would like the intensity of some lights to be adjusted based on ambient light conditions (namely LEDs on switches that I don’t want to be overly bright when it’s dark). I haven’t been able to find an easy-to-use light sensor. But it seems the Touch 70 screen has it’s own light sensor that it uses for screen brightness. It’d be great if I could access this through NodeRed, but I can’t find an Input Node for it. Am I missing something? If not, can Victron add this to their list of features to add? Anyone have a suggestion for an alternate way to get ambient light level detection into the Cerbo/Node-Red environment? (If not, I might just control the brightness based on time of day – but that’s less ideal.)
