dzVents version of the Solar Data Script [SOLVED]

[BakSeeDaa]

I get these errors sometimes too.
Perhaps the script could be changed to first save at an other tmp file and if that file is 0 bytes, the old file could be in place.
If the bytes are close to the previous file the file could be copied over the old one.

The error message just indicates that there is no Weather underground data to read. It can happen due to several conditions. Probably the Weather Underground server did not respond in time for some reason.

There is nothing to worry about really unless you get these error messages every 5 minutes (e.g every fetchIntervalMins). In such a case you'd need to investigate what's going on.

The dzVents version of the Solar Data Script informs you about the error condition but a single missing response from the Weather Underground server now and then shouldn't be any reason for worry.

I now get the following error:

2017-10-19 17:56:02.711 Error: dzVents: Error: SOLAR 2.1.1: There is no device with that name or id: 204
2017-10-19 17:56:02.712 Error: dzVents: Error: SOLAR 2.1.1: An error occured when calling event handler Solar Data

I just checked and there is a device 204. So I wonder where this comes from, and how to fix it

[hairynoggin]

anyone had success with this and windows? what are your settings? I keep getting

SOLAR 2.2.0: Could not read wuAPIData from file: C:\Domoticz\tmp\wuData.json

is this the correct format? local tmpFileWU = 'C:\\Domoticz\\tmp\\wuData.json' -- Temporary storage of WU API json result

I can't say. It's very little information to go on.

Did you define a cloud cover device? Is it a percentage device?

Make the script output some debug messages. Quote them here together with the configuration part (remove sensitive parts like the wuAPIkey). Also provide info about what dzVents version that you are using. The script requires dzVents version 2.3.0 or higher. Thanks.

The script requires curl in order to work. The script makes a few OS calls. For example:

Code: Select all

			os.execute('curl -s "'..url..'" > '..tmpFileWU..'&')

The above won't work on Windows. Feel free to experiment with it though. I add a note about it in the initial post. Thanks.

I should add that the temporary files that the script produces are all empty. the script definitely connects but for what ever reason no data is saved. this happens every 5 minutes

Thanks I will do some more testintg

Still having problems with this script

O, didn't see the newest version out

[BakSeeDaa]

O, didn't see the newest version out

OK, then after upgrading...

1) Did you define a cloud cover device?
2) Is it a percentage device?
3) Make the script output some debug messages. (

Code: Select all

level = domoticz.LOG_DEBUG

)
4) Quote debug output together with the configuration part (remove sensitive parts like the wuAPIkey).
5) Also provide info about what dzVents version that you are using. The script requires dzVents version 2.3.0 or higher.

Thanks.

[EdwinK]

Ah... Oaky. Just did a check and it seems that on the Synology version we are still on 2.2.0. Guess I'm out of luck for now, until Jumbotroll releases a new version of domoticz and that will only be after there is a new stable version ;(

[gajotnt]

Can you please add the UV index info from Weather Underground to this script?

[BakSeeDaa]

Can you please add the UV index info from Weather Underground to this script?

I have plans to release a brand new dzVents script for pulling Weather Underground data from a city or a specific PWS. The UV index will most likely be handled by that script. So hang on a while and watch out for any news in the dzVents Lua Framework forum table

Cheers!

[EdwinK]

Will do so

[gajotnt]

Thanks

just installed dzVents version, local scriptVersion = '2.2.1'

Two issues:
1) I have not created variable warnNoCloudDataHours, was waiting for the error but nothing (also there is NO info in the Wiki)
2) round error below

Suggestions?

Result:

Requires Domoticz v3.8551 or later

- What is your version?

In case you missed the prerequisite part and you'd like to upgrade to a Beta Version of Domoticz you'd need to wait because I created a nasty bug that hasn't been fixed yet.

[renerene]

Problem solved; it was in the new 'round' method. I was on 'stable' update, with old dzVents version.
I did see your advice just now, after the update.

Since Beta 39794, all timers based on sunrise/sunset do not function...

--> Oh well,if that is the only problem: no worry, will use my LUX variable for that now

Don't forget to backup first in case you need to revert for some reason. Cheers!

Good to know. Need to change some stuff then.
