Multi-day weather forecast to control device [Solved]

[Atis]

Hello,

I would like Multi-day weather forecast to control device. How can I set up that I can Using the forecast to control domoticz device?
I see 8 day forecast in domoticz, but I can not use this information to control the sprinkler or something else.
i added another weather forecast but in domoticz it only shows the current value.

I need temperature and rain forecast. Possibly if the amount of precipitation can be solved.

Thank you,

This information can be collected from openweathermap.org if you have a (free) API key and can be processed using a dzVents script.

What would you like to see in domoticz based on the data from openwathermap and on what devicetype(s)?
How would the control need to look like if you know the expected average-, min- and max temperatures and the expected amount of rain in mm per day for the next 7 days?

Hello Waaren,
I think 5-7 days max. celsius forecast divided into days. This info in temperatures sheet.
The rain data in mm for the next 5-7 days in weather sheet.

Could look like below. rain forecast data is in custom sensors (in the utility tab)

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents enabled' is checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state."

Hello Waaren, Thank you your script. Script is working but I have the problem with data:

Temperature: The script said 48 h and next 8 days max temp. 24.7 and 24.6. But I see the openwethermap page the teperature in next 8 day max 28-30Celsius.

Rain forecast: The domoticz said no rain today and the next 48 hours. But the wether site said light rain tomorrow 0,34 mm/h. 8 days rain forecast data not right. Can you help me?

The only things that can cause this are different lat / lon settings in domoticz compared to what you entered on the site or a problem at the openweathermaps.org site's data. The script will only process the data it gets from the site by summing, determining the max. There is no other interpretation in the script.

The figures I get using this API, match with what I see on the openweathermap for my city.

Which api using from weather api?


I have this:
Weather Current weather and forecast Free plan Hourly forecast: unavailable
Daily forecast: unavailable
Calls per minute: 60
3 hour forecast: 5 days

I see in json that correct rain and temp, but in domoticz data not good. I dont understand.

Can you please share your lat /lon (use PM ) to help me debug ?
I guessed Budapest and the data from openweathermap GUI matches the API exactly when grabbed at the same time. Maybe the script execution frequency should go to once per hour if you want it to be more accurate for the next couple of hours ?

What devices are you looking at and have you executed the script just before comparing it with the call from your GUI ?

This is what I see and that looks about right

Thanks for sharing your nice script! I want to add the minimum temperatures but I get an error that I can't resolve myself.

Updated script with option to add virtual sensors for minimum temperature 48 hours and minimum temperature temp 8 days.

Updated version with optional average temperature sensors. Also include a warning in the comments

Please note that dzVents requires acces to domoticz at a sufficient level to retrieve the location settings
including the latititude and longitude. It can only get these if the Local Networks (nu username/password)
include 127.0.0.1 (and ::1 for systems using IPv6)

@ waaren,

Thanks for sharing your script I have setup the requirements in domoticz: user variable, long, lat etc and the script runs, if i don't create the any virtual devices the script completes without errors;

The function deviceExists is not available in your version of dzVents. it was introduced in dzVents 2.4.28
You can find the dzVents - domoticz version relation here

@ waaren,

Thanks for the quick reply, that solved that mystery, better update to latest stable them

Emerson

[spider85]

Updated version with optional average temperature sensors. Also include a warning in the comments

Please note that dzVents requires acces to domoticz at a sufficient level to retrieve the location settings
including the latititude and longitude. It can only get these if the Local Networks (nu username/password)
include 127.0.0.1 (and ::1 for systems using IPv6)
Also explained in the wiki

        This script collects rain en temperature forecast data from openweathermap.org

        Next you need to create a uservariable (type string) and enter the openweathermap API key as value

Hi Waaren,

How and where do i need to put the APi and lat long?

There is a Pull Request on Github (https://github.com/domoticz/domoticz/pull/4284) for a big update of the OpenWeatherMap module in Domoticz which also includes the 8 day weather forecast as separate sensors including min and max temperature, probability of precipitation (rain, drizzle, snow, etc), etc.

If/once this Pull Request is merged into the beta, it can be tested to see if it has enough possibilities to control things like garden sprinklers, etc.

Tnx, got it working, is it possible to get the max temp for 24h (for the next day)?
If it is possible i could make a timing thing for my garden sprinklers.
