Display time of object

[Dré]

You will need two scripts for this.
1. Event script mapped to control or status object if the load:

Code:

value = event.getvalue()
key = 'ontime'
out = '32/1/5'

if value then
  if not storage.get(key) then
    storage.set(key, os.time())
    grp.update(out, '0m')
  end
else
  storage.delete(key)
  grp.update(out, '')
end

2. Scheduled script that runs every minute:

Code:

key = 'ontime'
out = '32/1/5'

time = storage.get(key)
if time then
  delta = os.time() - time
  minutes = math.floor(delta / 60)
 
  hours = math.floor(minutes / 60)
  minutes = minutes % 60

  if hours > 0 then
    res = hours .. 'h '
  else
    res = ''
  end
 
  res = res .. minutes .. 'm'
  grp.update(out, res)
end

32/1/5 is the object that shows the load ON time, set data type to 250 byte string. If you need multiple status outputs then use a unique storage key for each load (ontime in this example).

I have a question, i try to use this script more times
i change the names value, key and out on both of the script on all places.
so both scripts use different names.

but if i trigger the seconds action, the first timer start for 0 again, some know what i do wrong?

my first event script for Laptop Table

Code:

Laptop_Table = event.getvalue()        --'0 WCD Woonkamer - laptoplader eettafel (tm)'
ontime_Laptop_Table = 'ontime'
output_Laptop_Table = '32/1/201'    --'Laptop eettafel [timer on]'        

if Laptop_Table then
  if not storage.get(ontime_Laptop_Table) then
    storage.set(ontime_Laptop_Table, os.time())
    grp.update(output_Laptop_Table, '0 m')
  end
else
  storage.delete(ontime_Laptop_Table)
  grp.update(output_Laptop_Table, '')
end

my first Resident script for Laptop Table

Code:

ontime_Laptop_Table = 'ontime'
output_Laptop_Table = '32/1/201'            --'Laptop eettafel [timer on]'    

time = storage.get(ontime_Laptop_Table)
if time then
  delta = os.time() - time
  minutes = math.floor(delta / 60)
  
  hours = math.floor(minutes / 60)
  minutes = minutes % 60

  if hours > 0 then
    res = hours .. 'h '
  else
    res = ''
  end
  
  res = res .. minutes .. ' minuten'
  grp.update(output_Laptop_Table, res)
end

my second event script for Kitchen

Code:

Kitchen = grp.getvalue('1/4/4')            --'0 Verl. Kitchen (tm)'
ontime_Kitchen = 'ontime'
output_Kitchen = '32/1/202'            --'Kitchen [timer on]'    

if Kitchen then
  if not storage.get(ontime_Kitchen) then
    storage.set(ontime_Kitchen, os.time())
    grp.update(output_Kitchen, '0 m')
  end
else
  storage.delete(ontime_Kitchen)
  grp.update(output_Kitchen, '')
end

my first Resident script for Kitchen

Code:

ontime_Kitchen = 'ontime'
output_Kitchen = '32/1/202'            --'Kitchen [timer on]'

time = storage.get(ontime_Kitchen)
if time then
  delta = os.time() - time
  minutes = math.floor(delta / 60)
  
  hours = math.floor(minutes / 60)
  minutes = minutes % 60

  if hours > 0 then
    res = hours .. 'h '
  else
    res = ''
  end
  
  res = res .. minutes2 .. ' minuten'
  grp.update(output_Kitchen, res)
end

another thing,
for me it looks like line 1 and line 4 of the Resident script look like do the same thing, or m i wrong?
