Single high/low notification real time power smar meter

[GasDeKu 0]

Hi everyone, I need some advice.

I would like to ensure that when the power (watts) of a smart meter device (ID 855) falls below a threshold it is notified by a push/email notification and the same when the power falls within the set limits.

I made this script but unfortunately the notifications are continuous while I would like the notification to be only one. Could you give me a suggestion? Thanks

 

--[[
%% properties
855 power
%% weather
%% events
%% globals
--]]

local startSource = fibaro:getSourceTrigger();
if ( tonumber(fibaro:getValue(855, "power")) >= 10 ) then
    fibaro:call(2, "sendDefinedEmailNotification", "351");
    fibaro:call(859, "sendDefinedPushNotification", "351");
else
     fibaro:call(2, "sendDefinedEmailNotification", "350");
    fibaro:call(859, "sendDefinedPushNotification", "350");
end

Just a quick idea:
I would store something in a global var and
then check what the last message was (before sending)

sorry but I'm not a lua code expert.

What I wrote is the result of conversions from block diagram > lua plus something I found on the net.

Could you be more specific, perhaps with an example.

maybe like this:

if ( tonumber(fibaro:getValue(855, "power")) >= 10 ) then
    if hub.getGlobalVariable("LastMessage") == "351" then
     -- do nothing
    else
       -- send something
       hub.setGlobalVariable("LastMessage", "351")  -- set Variable
    end
else
    if hub.getGlobalVariable("LastMessage") == "350" then
     -- do nothing
    else
       -- send something
      hub.setGlobalVariable("LastMessage", "350")  -- set Variable

   end
end

Unfortunately it continues to send more than one notification.

 

--[[
%% properties
855 power
%% weather
%% events
%% globals
--]]

local hubID = 855

if tonumber(fibaro:getValue(hubID, "power")) >= 10 then
    if fibaro:getGlobal("LastMessage") == "351" then
        -- do nothing
    else
        -- send something
    fibaro:debug("Power OK")
        fibaro:setGlobal("LastMessage", "351")  -- set Variable
    end
else
    if fibaro:getGlobal("LastMessage") == "350" then
        -- do nothing
    else
        -- send something
        fibaro:debug("Power DOWN")
        fibaro:setGlobal("LastMessage", "350")  -- set Variable
    end
end
