Telegram message with blocking - AlexLV - 30.10.2022

Hi,

Boiler status I receive from powertag, updating periodically. I want message to telegram should be sent only once, when status changed. But my simple script not working, could not find where is the problem..

Can you please check where I am wrong..

Code:
require("user.telegram")

local statuss = event.getvalue('42/2/10')----Boiler status
local alarm = event.getvalue('0/0/102') ---alarm status
--log(statuss)
--log (alarm)
if statuss == true then 
if alarm == false then 
     message = 'Бойлер включен' ---message is not working, boiler is on
telegram(message)
grp.write('0/0/102', true)  -- trying to block next alarm
    alarm = true -- t
end
else 
 message = 'Бойлер выключен' --message working, boiler is off
  telegram(message)
    grp.write('0/0/102', false) -- trying to unblock next alarm when statuss is changed
  alarm = false
end

event.getvalue() does not accept any arguments. You need to use grp.getvalue() for all other groups than the event source.
Your script blocks multiple "on" messages but does not block "off" messages. Use this instead:

Code:
require('user.telegram')

key = 'boiler_status'

curr = event.getvalue()
prev = storage.get(key)

if curr ~= prev then
  message = curr and 'boiler on' or 'boiler off'
  telegram(message)
  storage.set(key, curr)
end
