Reset counter object each month

[Mr.D]

Hi,

I have iEM 3150 Power Meter running and are continuously counting my power consumption. I have mapped the power consumption to an KNX object  (1/1/1) so it shows me the total power consumption. However, this counter is not possible to reset.

I would like an object let say (2/2/2) that starts each month showing 0 as consumption and as the month progresses it increases. Then, the first day of each month, it starts all over again. This way I am able to track my consumption during the month and se how it progresses.

This is how i would do it

Add this as a event script to your total power consumption object.

Code:

kwhtot = event.getvalue()
kwhstart = 'kwh_usage_month_start'
kwhoutput = '2/2/2'

if storage.get(kwhstart) == nil then
 storage.set(kwhstart, kwhtot)
end

grp.write(kwhoutput, kwhtot - storage.get(kwhstart))

And this one as scheduled script with cron time 0 0 1 * * ,this would run 1 day every month.

Code:

storage.set('kwh_usage_month_start', nil)
grp.write('2/2/2', 0)

Is it possible to add to this script another object '3/3/3' that registers the last maximum value of the object '2/2/2'? so we can visualize the last consumption of the previous month.

Hi,

possible to use different variants, as use trends:

https://forum.logicmachine.net/showthrea...umentation

but I think for you easiest way is create scheduled scripts, and write to the different groups data of power consumption at 0:00 every 1st day for every month (you will have 12 scheduled scripts). So you will see consumption for starting of month:

Consumpted_Energy = grp.getvalue('33/5/30') -- Group of your Energy meter with consumed energy
grp.write('33/7/13', Consumpted_Energy) -- April. There will be saved data of consumed energy for 0:00 of 1st April

The same for May and so on..:

Consumpted_Energy = grp.getvalue('33/5/30') -- Group of your Energy meter with consumed energy
grp.write('33/7/14', Consumpted_Energy) -- May. There will be saved data of consumed energy for 0:00 of 1st May

For previous month just EnergyPrevious = grp.getvalue('33/7/14') - grp.getvalue('33/7/13') -- For April. You should think also about other month..

Just easy calculations Of course such way you can show consumption for every day/week... etc. For me I show consumption from month start:

(Add this to event script for group where is recorded your consumed energy. So all recalculations will be done automatically when data upgrades (in example 33/5/30)).
MonthConsumed = grp.getvalue('33/5/30') - grp.getvalue('33/7/13' --

Also there you can add cost of energy:
EnergyCost = 0.16 -- (EuroCents per kWh) your cost

MonthEnergyConsumedCost = MonthConsumed * EnergyCost

grp.write('33/5/50', MonthEnergyConsumedCost) -- group you will store cost of consumed energy

This is just description of easy steps, let's try to play with..

Add this at the start of scheduled reset script (before 2/2/2 value is set to 0):

Code:

grp.write('3/3/3', grp.getvalue('2/2/2'))

Add this at the start of scheduled reset script (before 2/2/2 value is set to 0):

Code:

grp.write('3/3/3', grp.getvalue('2/2/2'))

Thank you very much Admin, it works.

In my opinion after the reset, this script is missing a counter status send. The monthly meter needs a first value to start the account. If it is not sent, a small value is lost in consumption.

After the reset, I added this script.

Code:

grp.write('1/1/1', grp.getvalue('1/1/1'))
