Display time of object

[Nir70]

Make sure you use a scheduled script that runs every minute not a resident script with low or 0 sleep time.

I did not understand, I used your scrap, I should change something there (in scrap)?

This solution consists of two scripts:
1. Event script which saves the time when the load has been turned on
2. Scheduled script that calculates the run time every minute
If you say that you get high CPU load then check that the second script is not a resident script with 0 sleep time.

This is how the scheduled script should be configured:

i change my event based script (a little), i had the problem, when i again get a off on my event, i got my value twice or more 'Last Run: '..Last_Run..' on'..time

so on my visualization i saw 'Last Run: Last Run: Last Run: 00:06 on Thu, 30-12 on Thu, 30-12 on Thu, 30-12'

Code:

Laptop_Seat = event.getvalue()            --'0 WCD Woonkamer - laptoplader Seat (tm)'
ontime_Laptop_Seat = 'ontime_Laptop_Seat'
output_Laptop_Seat = '32/1/202'            --'0 WCD Woonkamer - laptoplader Seat [timer on]'

if Laptop_Seat then
  if not storage.get(ontime_Laptop_Seat) then
    storage.set(ontime_Laptop_Seat, os.time())
    grp.update(output_Laptop_Seat, '00:00')
  end
elseif               -- <------------ and this to elseif
         storage.get(ontime_Laptop_Seat) then        --  <------------i add this line
  Last_Run = grp.getvalue(output_Laptop_Seat)
  time = os.date(' %a, %d-%m',time)
  grp.update(output_Laptop_Seat, 'Last Run: '..Last_Run..' on'..time)
  storage.delete(ontime_Laptop_Seat)
end

Modified script version that has total and current running time.
1. Add to Common functions:

Code:

function formattime(output, seconds)
  local minutes = math.floor(seconds / 60)
  local hours = math.floor(minutes / 60)
  local days = math.floor(hours / 24)
  local res = {}

  seconds = seconds % 60
  minutes = minutes % 60
  hours = hours % 24

  if days > 0 then
    res[ #res + 1 ] = days .. 'd'
  end

  if hours > 0 then
    res[ #res + 1 ] = hours .. 'h'
  end

  if minutes > 0 then
    res[ #res + 1 ] = minutes .. 'm'
  end

  if seconds > 0 or #res == 0 then
    res[ #res + 1 ] = seconds .. 's'
  end

  res = table.concat(res, ' ')
  grp.update(output, res)
end

2. Event script mapped to load on/off status:

Code:

value = event.getvalue()

key_curr = 'ontime_curr'
out_curr = '32/1/5'

key_total = 'ontime_total'
out_total = '32/1/16'

time = storage.get(key_curr)
now = os.time()

if value then
  if not time then
    storage.set(key_curr, now)
    formattime(out_curr, 0)
  end
else
  if time then
    time_total = storage.exec('incrby', key_total, now - time)
    formattime(out_total, time_total)
   
    storage.delete(key_curr)
  end

  grp.update(out_curr, '')
end

3. Scheduled script that runs every minute (or a resident script with sleep time > 0 if finer time resolution is needed):

Code:

key_curr = 'ontime_curr'
out_curr = '32/1/5'

key_total = 'ontime_total'
out_total = '32/1/16'

time_curr = storage.get(key_curr)
if time_curr then
 
  time_curr = os.time() - time_curr
  formattime(out_curr, time_curr)
 
  time_total = storage.get(key_total, 0)
  formattime(out_total, time_total + time_curr)
end

In both scripts key_curr, out_curr, key_total, out_total variables should be adjusted as needed. Make sure that these variables have the same values in both scripts.
