Multiple Value true

You need to use storage to save current fault state so message is sent only once on status change:

Code:

FAULT1 = grp.getvalue('14/1/34') -- Status FAULT1
FAULT2 = grp.getvalue('13/1/34') -- Status FAULT2

fault_status = storage.get('fault_status', false)

subject = 'FAULT'
message = 'FAULT'

subject1 = 'OK'
message1 = 'OK'

if FAULT1 == 10 or FAULT2 == 10 then
 if not fault_status then
   mail('@', subject, message)
   storage.set('fault_status', true)
 end
else
 if fault_status then
   mail('@', subject1, message1)
   storage.set('fault_status', false)
 end
end

Perfect as always.
Thank you so much.
