# This script is developed by LJB due to a lack of decimal number support when calling the volts value from system health. It is only tested and verified with ROS 7.19.4 on an RB2011UiAS-RM # Battery volts offset measured in dV (deciVolts) - do not add a period or comma :local offset "22" #define …

23.45 dot pos [find dot] part 1 = pick from start to dot pos = 23 part 2 = pick after dot pos to end = 45 final= part1 + part2 = 2345 done.

My initial try I failed several times to pick part two as referenced in your reply hence the different approach above.

Ok, I have to ask. What (the heck) is the initially set voltage offset? A difference (measured with a multimeter or oscilloscope or whatever) between the voltage reading of the board and the actual voltage? Why decivolt? The board measures in volts - dot - hundreths of volts, doesn't it? The "l…

Hi @jaclaz The offset specified is to compensate for the volt difference I have between the router and the battery source due to a long-distance cable. Perhaps one can start with a zero-rated offset. I am updating the original post. deciVolt is a tenth of a single Volt, not a hundredth. Perhaps, i…

@rextended Great, with magic you make it appear so simply and easily. I am just a beginner. Perhaps one day I'll be at your level. The :tonum function sounds interesting. I will have to note that down for next time.
