Controlling Temp with timer

[ajgarcia.reyse]

Hi all,

I am monitoring water temperature with LM and KNX, but I need send email when current temperature is higher than "max limit" during one period of time (e.g. 60 min).

Anyone could help me? Thanks

Create an event script mapped to temperature object:

Code:

12345678910111213

temp = event.getvalue() curr = temp > 22 prev = storage.get('temp_over') if curr ~= prev then   if curr then     storage.set('temp_time', os.time())     storage.set('temp_notified', false)   end   storage.set('temp_over', curr) end

Then create a scheduled script that runs every minute to check whether e-mail needs to be sent. Change delta time if needed (60 * 60 = 1 hour in seconds).

Code:

123456789101112

curr = storage.get('temp_over') notified = storage.get('temp_notified') if curr and not notified then   now = os.time()   time = storage.get('temp_time', now)   delta = now - time   if delta > 60 * 60 then     -- send email     storage.set('temp_notified', true)   end end

Thank you very much!! Script works perfectly on my LM. Is there any handbook or manual to learn advanced scripts in LUA???

Common LM/Lua functions are documented: http://openrb.com/docs/lua.htm

As for more advanced things, have a look at example in forums and on our website. There are some many possible solutions and approaches that it's just not possible to document them.

Hello,
This function is very useful.
I use it to check a temperature for 5 minutes if it goes above 23 ° C so I send an email.
If possible, I would like to send an email when the temperature drops below 23 ° C.
This email must be sent only after a temperature fault and not every time the temperature is below 23 ° C.
thank you. B. R.

Event script:

Code:

12345678910

temp = event.getvalue() curr = temp > 23 prev = storage.get('temp_over') if curr ~= prev then   storage.set('temp_time', os.time())   storage.set('temp_notified', false)   storage.set('temp_over', curr) end

Scheduled script:

Code:

12345678910111213141516171819

notified = storage.get('temp_notified') if not notified then   curr = storage.get('temp_over')      now = os.time()   time = storage.get('temp_time', now)   delta = now - time      if delta > 5 * 60 then     if curr then       text = 'temp over limit'     else       text = 'temp under limit'     end     -- send email     storage.set('temp_notified', true)   end end
