dzVents version of the Solar Data Script [SOLVED]

[Bishop]

Since a few days I noticed my Lux value wasn't update every 5 minutes. So I went to check the logs and every now and then, few times per hour, it seems Domoticz is unable to reach ogimet.com. Is anyone else experiencing the same?

I can't seem to get the script working:

I really want to change to the dzVents version because the LUA one seems to run every second (after a while).
Does anyone has a solution for this nil value thing?

I'm a domoticz newbie and interested in the automation of my Somfy sunscreen.
Is it possible to use this script in Belgium en with adaptations have to be made?
How can the dzVents script be activate in the domoticz event system?
Can somebody help me please?

@Bruno, to activate this- or any other dVents script in domoticz please read the dzVents wiki and specific the Using dzVents with domoticz section.

Script should work in Belgium without changes if you enter all the right settings in the config part. (between lines
-- Variables to customize ------------------------------------------------

and

-- Please don't make any changes below this line (Except for setting logging level)

@ waaren

Thank you for your quick answer and the link.
I'll do my best to try to understand the explanation and to create a dzvents event in domoticz but i am not a programmer at all
All other parameters in the wuSettings file have been entered as asked.

I also wasn't a programmer, but... Just start
I use the dzvents wiki a lot and combine it with examples from other scripts in the forums.

Hi all,

As many of us have surely noted, WU does not give anymore free API keys, so new users of WU (and Domoticz, like me) do not have a way to get the pressure data needed by this script.

But I've noticed that the Ogimet service (at least the station I'm using) does report such pressure values, so a single query to Ogimet can give both cloud cover & pressure values. I'm now in the process of modifying the script to use only Ogimet but, in the meanwhile, does anybody know of a reason to prefer the pressure values reported by WU instead of the ones from Ogimet?

I'm wodering, also, about the reason to use the latitude/longitude values from WU instead of those in Domoticz settings. I'll try to modify the script to use these.

But, be patient, I'm really new to domoticz (just 2 days) and to Lua (just a few hours).

Regards.

hello,
Lua script is working properly, DzEvent script not really, virtual sensors are not updated, and there is not any error reported. Strange
Any idea?
Thanks

I decided to finaly replace the old LUA version of the script by the DzVents version.

I copied the script from the initial post and came across these errors:

line 207:

Code: Select all

if(sinAzimuth		local sunstrokeDuration = math.deg(2/15 * math.acos(- math.tan(math.rad(latitude)) * math.tan(math.rad(declination)))) -- duration of sunstroke in the day . Not used in this calculation.

This 'error' is displayed when I view the post with the tapatalk app only. Opening this topic in a web browser displays the correct code:
if(sinAzimuth<0) then azimuth=360-azimuth end
local sunstrokeDuration = math.deg(2/15 * math.acos(- math.tan(math.rad(latitude)) * math.tan(math.rad(declination)))) -- duration of sunstroke in the day . Not used in this calculation.

Line 253:

Code: Select all

elseif sunAltitude = -7 then -- apply theoretical Lux of twilight

Should be:

Code: Select all

elseif sunAltitude == -7 then -- apply theoretical Lux of twilight

[JCLB]

Someone should adapt the script by using data from other sources, and use domoticz virtual sensors whenever possible, why try to get data from WU or Accu or DarkSky as they're all included in domoticz, script would be more simple and concentrate on maths and not API calls:

• pressure read from weather sensor (with idx for each one, up to you to choose between real ones and virtual
• latitude, longitude, altitude set manually
• cloud cover fetched from DarkSky API in this script instead of the dying ogimet or from a local virtual sensor with this script viewtopic.php?f=61&t=22090&p=188573 and then change the calcul to use % instead of octa

Hi,

I just discovered this script and since the WU API is not available anymore, I took the liberty to adapt the dzEvent script to use Dark Sky API.
I made some changes to follow JCLB's advices about :
- the pressure (which is defaulted to Dark Sky but can be taken from a device)
- latitude, longitude and altitude have to be set manually since I didn't find another way to detect them
- Cloud cover is retrieved from Dark Sky API and the subsequent algorithm is modified (even if I didn't renamed the variable "okta")

It's a shame that the cloud cover isn't supported by the Dark Sky hardware in DZ. I could have made it "datasource independent" so that it relies only on dz devices.

The script is avaiblable at https://github.com/russandol-sarl/dz-solarData.

Feel free to share ! If you have any improvements in mind, you can tell me and I'll see what I can do.

Hi,
I've writen a DzVents script to get values from DarkSky, with pressure and cloud cover => all put in dz device
It works fine except for the rain because rain sensors are a strange thing in Domoticz - I work on it when I time and when it's raining
I also have rain expectation for the next 1h, 12 and 24h (for a future watering system)
This could be a start to split the datasources from the algorithm

Meteo_V0R9d
from https://www.domoticz.com/forum/viewtopic.php?t=22090 (Cloud cover from darksky by aleph0)

to read: https://darksky.net/dev/docs

extract from several emails with DarkSky support to understand their data:
<<precipProbability is the probability of any precipitation at all in the corresponding hour,
while *precipIntensity* is the expected amount of precipitation.
Technically *precipIntensity* is a rate, but it is per hour, so the number is also the expected amount for the hour for which it's reported>>
<<for the next 24 hours, you simply want to sum precipIntensity for each hour,
since it is the expected precipitation amount per hour for those hours>>
<<Regarding the probabilities for "current" conditions:
think of the probabilities as representing our uncertainty about events rather than a direct probability of an event occurring.
Because there are not stations at every location in the world and their data is not perfect, even historical observations have some uncertainty>>

Hi,
I've writen a DzVents script to get values from DarkSky, with pressure and cloud cover => all put in dz device
It works fine except for the rain because rain sensors are a strange thing in Domoticz - I work on it when I time and when it's raining
I also have rain expectation for the next 1h, 12 and 24h (for a future watering system)
This could be a start to split the datasources from the algorithm

<..>

The logs tells me:

HI
sorry my comments in the script were not very accurate. I've changed them
So
local dev_rain1h = youridx -- dummy receive 1h expected rain in mm / Custom (mm)
local dev_rain12h = youridx -- dummy receive 12h expected rain in mm / Custom (mm)
local dev_rain24h = youridx -- dummy receive 24h expected rain in mm / Custom (mm)
local dev_cloudCover = youridx -- dummy receive cloudCover / SubType Custom Sensor (no unit, I put a / in the unit besause it is mandatory)

=> all this sensors are custom to summarize !

(for the last one I choose custom to be able to change the icon, I could not on a % type ; you could choose % as a unit and multiple by 100 if you want )

Hope this help!

Sorry, i don't understand your comment.

The values in the script are:
local dev_rain1h = 105 -- dummy receive 1h expected rain in mm / Type Rain -> Custom (mm)
local dev_rain12h = 106 -- dummy receive 12h expected rain in mm / Type Rain -> Custom (mm)
local dev_rain24h = 107 -- dummy receive 24h expected rain in mm / Type Rain -> Custom (mm)

All 3 are Dummy devices and the sensor type are set to Rain sensor.

The script is avaiblable at https://github.com/russandol-sarl/dz-solarData.

Feel free to share ! If you have any improvements in mind, you can tell me and I'll see what I can do.

You did an awesome job, thanks!
But, there is something wrong with the script or i made a mistake myself implementing it.

Currently it is cloudy in the netherlands and the current indicated Lux value 13370.

The Lux wiki tells me that a clouded day is around 1000 Lux.
So 1337 Lux should be very cloudy

I think the "0" in the end should not exist or i made a mistake with the script and idx values but i've checked them three times so far so i don't know how i could do something wrong..

Ok, thanks for the info!

What settings do u use for cloudcover?
Because i still receive the following error message:

Meteo: Method updateCustomSensor is not available for device "CloudCover" (deviceType=General, deviceSubType=Percentage). If you believe this is not correct, please report.

For some reason i can not get this to work properly.
What am i doing wrong?

ocal dev_rain1h = 105 -- dummy receive 1h expected rain in mm / Custom (mm) =>> not rain type but custom type
local dev_rain12h = 106 -- dummy receive 12h expected rain in mm / Custom (mm) =>> not rain type but custom type
local dev_rain24h = 107 -- dummy receive 24h expected rain in mm / Custom (mm) =>> not rain type but custom type

Ok, thanks for the info!

What settings do u use for cloudcover?
Because i still receive the following error message:

Meteo: Method updateCustomSensor is not available for device "CloudCover" (deviceType=General, deviceSubType=Percentage). If you believe this is not correct, please report.

device "CloudCover" => General Custom Sensor /!\ not a % device
after in the axis of the custom sensor you put what you want, there is no unit for the cloud sensor
