Tasmota voltmeter (#1397)
* added millivolts to tasmota_ to get ANALOG/Range value * allow to print_thresholds in tasmota plugin * Experimented with different graph settings to obtain best axis labels If voltage limits were eg 11 and 14 volts, the labels and limits default terribly to 10 to 20, and if you fix limits, then labels read "11, 11, 11, 12, 12, 12, 13, ...". alt-y-grid and alt-autoscale seem to improve this a lot * get_value -> get_status to better reflect what it's doing * millivolts() forgot to account for invalid value "U" --------- Co-authored-by: Tim Connors <tconnors@rather.puzzling.org>
