036 is missing. It is the option to set the state of logging and it is one of the ‘special’ binary options. It should be added to the options list with shading as it may need to be included in the command to maintain the state of logging.
Thanks for this info DaveC, I referenced the API document only to find my logging had been turned off when adjusting wl (watering level) 8-(
Bit of a trap when the API Document is incorrect.
