Rolling PIN Code

[KoBra]

Use the following functions to set plan/widget pin code. For widget you need specify both plan ID that contains the widget and the widget ID. Plan ID / widget ID can be found in the window title when editing.

Important: pin code value must be a string. New pin code must have the same length as the previous.

Code:

function setplanpin(planid, pincode)   local json = require('json')   local structure = storage.exec('hget', 'app:visu:main', 'structure')   local function setpin(items)     for _, item in ipairs(items) do       if item.id == planid then         item.pincode = pincode         return       end       if type(item.children) == 'table' then         setpin(item.children)       end     end   end   structure = json.decode(structure)   setpin(structure)   local data = json.encode(structure)   storage.exec('hset', 'app:visu:main', 'structure', data) end setplanpin(41, '123456')

Code:

function setwidgetpin(planid, widgetid, pincode)   local json = require('json')   local key = 'widgets:' .. planid   local widgets = storage.exec('hget', 'app:visu:main', key)   widgets = json.decode(widgets)   for _, widget in ipairs(widgets) do     if widget.id == widgetid then       widget.pincode = pincode       break     end   end   local data = json.encode(widgets)   storage.exec('hset', 'app:visu:main', key, data) end setwidgetpin(41, 42, '123456')

Could i load the PIN from a 250byte string object?
In this way i could write the PIN to the datapoint when i load it from the PIN Generator at the tennis federation (in this case)
