I made a mistake again, I took the "06" feature index from the spec, but your K750 uses "09" as index for 4301 Solar Dashboard. 06 is an unknown hidden feature, 1DF3. Hopefully this did not break anything :P Can you try: ./shell hidw /dev/hidraw0 10 02 09 0f 01 01 Explanation (so you can check it yourself): 10 - short HID++ message 02 - device index 2 (presumable K750 device) 09 - feature index 9 (for Solar Dashboard feature) 0F - function 0 (SetLightMeasure), software ID 0xF 01 - report count (one time) 01 - report interval (one second) A notification should appear within a second of the request.
