Check PV production with sunpower (persistent data)
Posted: Thursday 10 September 2020 20:56
by riko
I'm trying to build a script to check whether my solar panels work properly. I found out that the 'Sun Power' device of Buienradar is a good predictor for the real production (real production is about 2,9 times higher than Sun power). The output is a level/color in the alert device that should be updated.
The first part of the script seems to work okay. From the moment I'm commenting the parts it is trial and error and returning error codes.
It is my first time to use persistent data with history and I think the error is caused because I'm storing a string instead of numeric values. The devices (Sun Power as well as Production) are both custom sensors. Though as you can see I've already changed the data tonumber() before adding to the database.
Does somebody know whether I'm filling the database properly and how I can retrieve these values?
Code: Select all
return
{
active = true,
on = {
devices = {
6, -- IDX van SunPower
24 -- IDX van Productie zonnepanelen in W
}
},
logging =
{
level = domoticz.LOG_DEBUG, -- change to LOG_ERROR when OK - was LOG_DEBUG
marker = 'Zonnepanelen_defect'
},
data = { solar = { history = true, maxHours = 25, maxItems = 1000 }},
execute = function(dz, item)
local round = dz.utils.round
local Solar_theoretical = dz.devices(6) -- IDX van SunPower
local Solar_production = dz.devices(24) -- IDX van Productie zonnepanelen in W
local Alert = dz.devices(46) -- Alert device
local lastTheoreticalWatt = round(tonumber(Solar_theoretical.state),1)
local lastProductionWatt = round(tonumber(Solar_production.rawData[1]),1)
dz.log('lastTheoreticalWatt: ' .. lastTheoreticalWatt .. ' W',dz.LOG_DEBUG)
dz.log('lastProductionWatt: ' .. lastProductionWatt .. ' W',dz.LOG_DEBUG)
dz.data.solar.add -- Store current values in persistent historical data
(
{
['theoretical'] = lastTheoreticalWatt,
['production'] = lastProductionWatt
}
)
-- dz.log(dz.data.solar.get(2),dz.LOG_DEBUG)
local sum_2hr = dz.data.solar.sumSince('00:01:00')
dz.log('test ' .. sum_2hr .. ' test',dz.LOG_DEBUG)

This is the error:

You store a set in persistent historical data. This is possible but if you do that you cannot use the statistical functions like sum and avg without a helper function. Explained
here .
You will make your code easier if you just store numbers (like below)
Also; Please note that having 1000 entries in persistent historical storage will have significant impact on performance.

Thanks waaren, impressed by your skills and speed! It's working. I've read the concept of the helper function, but didn't get it
Luckily I don't need it this way.
I'm now working on the alert sensor update criteria and will share the final results of the script for reuse.

This is the result. Using the status to update the alert device (IDX 46). I have to check the performance due to the big numbers in the database. The devices are updated every 30 seconds, meaning that 24 hours of data equals 24*60*2 = 2880 records

In fact it is even more as the script is triggered by both devices and you update the persistent data regardless of what triggered the script.
So 2 * 2 * 24 * 60
I would be very surprised if this is going to work (performance wise) as the script will eventually have to read and interpret 10000 rows from persistent data 4 times a minute.
Probably you will need to aggregate the data in some way

Wow I've missed this update, sorry! Great work again.
The script is running for a few days now without the aggegration and no issues yet. What kind of problems do you expect? CPU? Memory? I would like to try your aggegrating script later on. But I've made quite some adjustments in the meantime so it takes some time to integrate it.

Probably IO will be the first exhausted resource. How much time is there now between start and finish of the script? And what do you see when you look in <domoticz dir>/scripts/dzVents/data/

Only 1 second:

The data file is data folder is 260kb.
Not bad at all I think? The script is at least running every 30 sec at daytime (that is the frequency my solar panels are updating the data). Not sure how often the Buienradar data is updated (which is also triggering the script)

Indeed much better then expected. But please be aware that during the time a Lua, dzVents or Blockly script is active no other event-scripts can start and writing 240K every 30 seconds might also wear your sd-card prematurely.
For comparing you might want to check how long a dzVents script without a data section runs before finishing.

Thanks for the tips. I've put your aggegrated version of the script on my backlog. But will take some time to experiment with.
In this context: i have a lot of scripts running for instance every 5 minutes. Starting at 00:05, 00:10, etc. Is there an option to run a script every five minutes (or every hour etc) but then a bit shifted? For instance 00:06, 00:11, ...
