How check the power absorbed?

I’d like to check if my washer has finished to wash.
My xiaomi plug give me back the power in Watt that I’m consuming
During the washing cycle the power can go to zero sometimes for few minutes and then rise up depending what the washer is doing.
When the washer finish the power goes to zero.
There is a way in dzevents to control something like
Code: Select all
If power is =0 in the last 10 minutes then switch of
Thanx in advance

Yes, this should be possible, maybe not as easy as you suggest, but it's possible. See wiki

No, i’ve written scripts in dzevents but in this case I don’t know how start

I've just realized a script for that....
it works in this way:
a Watt consumption treshold above which it start the monitoring process and under whitch it start counting a specific amount of minutes after whitch is consider the cycle ended.
you will need an integer user variable (mine is called cycleMonit) to initialize to 0
here is the script:
Code: Select all
local delay = 20 -- minutes to wait to consider the duty cycle ended
local trig = 80 -- WATT below treshold
return {
on = {
devices = {'WAT_Lavatrice'},
timer = {'every minute'}
},
logging = {
level = domoticz.LOG_INFO,
marker = "[MonitCycle: LAVATRICE]"
},
execute = function(dz, devWat, tgInfo)
local cycleMonit = dz.variables('cycleMonit')
if tgInfo.type == dz.EVENT_TYPE_TIMER then -- cycle Monitor
dz.log('Monitoraggio attuale: '..cycleMonit.value..'/'..cycleMonit.lastUpdate.minutesAgo, dz.LOG_FORCE)
if cycleMonit.value == 2 and cycleMonit.lastUpdate.minutesAgo >= delay then
cycleMonit.set(0)
dz.notify('Fine ciclo Lavatrice', 'Credo che la lavatrice possa avere finito il proprio ciclo di lavoro')
end
elseif tgInfo.type == dz.EVENT_TYPE_DEVICE then -- WATT updater
if devWat.WhActual > trig and cycleMonit.value ~= 1 then
cycleMonit.set(1)
elseif devWat.WhActual < trig and cycleMonit.value == 1 then
cycleMonit.set(2)
end
end
end
}
based on the script... after 20 minutes of consumption under 80Watt, it consider the cycle ended

great i'll study it because i don't know so much about functions
Thanx for now

this is a function... the main script is this?

yes... i have just a dubt,
1) in device u trigger WAT_lavatrice i think is the seat plug you have in the function doesn't appears something like
Code: Select all
execute = function(domoticz, device)
but
Code: Select all
execute = function(dz, devWat, tgInfo)
i can't understand that.. what are devWat and tginfo?

Basically the same as I do with my PC. When the power is below 30watts for about 15 minutes, I switch off the zwave (in this case) switch. (Without dzvents btw)

ok... You have to understand the dzVents framework structure then...
the trigger of the script is based on 2 separates events:
Code: Select all
on = {
devices = {'WAT_Lavatrice'},
timer = {'every minute'}
},
a DEVICE info based on the update coming from the device WAT_Lavatrice (which is in my case the power consumption on the plug attached to the washingmachine)
a TIMER eventi that triggers every minute.
Why? because the device trigger must do some stuff (compare values and act by consequences) while the timer function have to count (if necessary) the minutes passed
Code: Select all
execute = function(dz, devWat, tgInfo)
dz, devWat,tgInfo are simple names... they could be even named domoticz, device, triggerinfo or foo, bar, zoo.... you just have to respect them in the code
dz (or domoticz) = the entire Domoticz table containing all the nodes, variables and other useful stuff
devWat( or device) = contain ONLY the information about the device/variable that trigger the event, in case of timer info the table in null
tgInfo = the trigger information. this is a special table that contains information about why the scripts have been triggered
hope this will helps you to better understand it

yesss, now is clear...
i'm just starting with dzevents
thanx for now
