Average power for the last clock hour - Rune - 06.11.2022
Hi guys!
Part of the energy cost in Norway is defined by the three hours in the month were the user spent the most power.
Can someone help me with a script that calculate the average power of the last clock hour? It would be nice to have that to confirm if I exceeded my 5kW limit or not.

I think I have one of those.. we'll talk tomorrow ?

If there is more than a screenshot of half a script, then ok.
No, wait, I have KNX Basic course this week.

Why not use Trends for this?
RE: Average power for the last clock hour - tomnord - 07.11.2022
I agree with Admin, a nice trendview would give you what you need.
RE: Average power for the last clock hour - Rune - 07.11.2022
Uhm.. Because I want it as a value in my other user interface. :|

You can get values from trends and write them to objects: https://openrb.com/docs/trends-new.htm

I couldn't understand how to transform that to a script that could be useful, so I googled lua average value and found this in another thread:
-- storage key
key = 'temp_average'
-- time between average value send (in seconds)
maxtime = 60 * 60
-- resulting average value
result = '4/3/34'
time = os.time()
data = storage.get(key)
if not data then
data = { values = {}, time = time }
end
value = event.getvalue()
table.insert(data.values, value)
delta = time - data.time
if delta >= maxtime or delta < 0 then
storage.delete(key)
avg = 0
count = #data.values
for _, value in ipairs(data.values) do
avg = avg + value
end
grp.write(result, avg / count)
else
storage.set(key, data)
end
Is there a way to make this start the count at the beginning of the clock hour?

you can use 'Scheduled' en put the scipt there.
Set running for every hour at 00 minutes

But if I do that, since it is a event script today triggered by "4/6/1", how do I insert that GA into the script before I change it to a sceduled script?

Event script:
Code:
local st_name = 'average' -- Local table name
local value_in = '4/6/1' -- GA data input
local st_table = storage.get(st_name)
if not st_table then
log('Table Created')
local st_values = {}
storage.set(st_name, st_values)
end
table.insert(st_table, grp.getvalue(value_in))
storage.set(st_name, st_table)Scheduled script sent every 0 minute:
Code:
local st_name = 'average' -- Name on local table
local result_avg = '4/3/34' -- GA for result output
local st_table = storage.get(st_name)
if st_table then
local size = 0
local sum_val = 0
for i, v in pairs(st_table) do
sum_val = v + sum_val
size = size + 1
end
local avg_val = sum_val / size
grp.write(result_avg, avg_val)
local reset_table = {}
log(avg_val)
log(size)
storage.set(st_name, reset_table)
log(storage.get(st_name))
end
