Telegram message with blocking

[AlexLV]

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:

12345678910111213141516171819

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:

123456789101112

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
