Has someone already a script which shows electricity prices today and tomorrow in a text device?
I'm struggeling already for hours with it. User vars do show correct values.

This is wat i use for the hourly price today:

Code: Select all

return {
    active = true,

    on = {
        timer = { 'every hour' ,-- 'every minute',
                 'at 0:07' },

    },

    execute = function(domoticz, trigger)
        local TEXT_IDX = 436
        local PRICE_SENSOR_IDX = 444 -- has to be set to correct value below near the end of the script, i was lazy!!!
        local headerText = 'Zonneplan stroomprijs (€/kWh)<br>━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━<br>'
        local URL = 'http://127.17.0.2:80/json.htm?type=command&param=getuservariable&idx=9'

        local function spaces(n)
            return string.rep('&nbsp;', n)
        end


        -- 1. TIMER → HTTP ophalen
        if trigger.isTimer then

                callback = 'zpPrices'
            })
            return
        end

        -- 2. HTTP RESPONSE → verwerken
        if trigger.isHTTPResponse then

    end
}

My Domoticz runs in Docker on a Synology nas so i use 'http://127.17.0.2:80' to reach inside the container, adjust accordingly

I get the stats for Zonneplan from the Enever website at midnight once and these are stored under user-variable 9.
Every hour the correct hour is highlighted and a custom sensor is updated with the price of the hour.

This works 99% of the time correct but this script will become somewhat obsolete after the 1st of august because Zonneplan is moving to quater hourly prices then.
The script works good for me on a windows laptop showing chrome, don't know how it wil look on other devices..

to what refers : getuservariable&idx=9 (enever name? if so pls which?)

RonkA · Post by **RonkA** » Sunday 05 July 2026 18:18

That is the uservariable IDX where in my Domoticz the string of data from Enever (Enever_Electricity_22) is stored, see Setup-More Options-User variables what your IDX is.

Why a text device? Why not create a custom template page for it like the screenshot below

Nice!! Personally i have not tried custom template's yet, but what i have running now is simple and easy to read on the dashboard by the whole family here... And i'm a fan of textdevices..(i use them a lot

)

BartSr · Post by **BartSr** » Monday 06 July 2026 9:35

Is custom template a new feature? I am not aware until now.
Re. enever plugin: is it normal behaviour thet uservar tomorrow shows now (9:33h) values of today as the tomorrow value is available kn the afternoon .

RonkA · Post by **RonkA** » Monday 06 July 2026 10:12

Yep, the tomorrow data of yesterday is not cleared at midnight, but i don't use the Enever plugin anymore since the plugin stopped functioning 2 months ago for a view Weeks..

I have this separate script to get the user variables updated, it uses 5 requests per day so it's well under the 250 request limit from the Enever account..
It's a simple script and it just works 99% like i want it to do.. (for now...)
The reason of the timing in the script to not to run exactly on midnight is because Enever site can take a view minutes over the hour updating the new data..

Code: Select all

return {
    active = true,

    on = {
        timer = {

I've created a Domoticz Zonneplan plugin for personal use (provided as-is): https://github.com/frepke/Zonneplan-Domoticz-Plugin

With the included dzVents script below (which depends on the plugin and a text device), you can get this:

Hi gizmocuz, "Why not create a custom template page for it like the screenshot below"
You mean the custom html page in the templates map?
With what graph engine did you create that page? Grafana? Could you please post an example HTML of yours?
Thanks!

Quick remark,
Zonneplan is just 1 Dutch energy supplier, also Enever is supplying data for a lot of Dutch energy suppliers..
So not all the users of Domoticz wil this be useful if they use another supplier and certanly not useful for people living outside the Netherlands..

Yes that's correct, but the Enever prices aren't always the correct ones for Zonneplan so I decided to make a plugin which shows the same prices as the Zonneplan app/website because it uses Zonneplan as source.

Ok, my remark was pointed at infoed's post, it's not about your plugin..

To your contribution to this thread i want to say that the plugin looks great on your dashboard!! and i will try to install and use it in the near future in my setup..
The text-device created is IMHO waayy to long and spacious for my liking so i wil not be using that in it's original form but maybe rewrite it sometime to keep it at 24 hours displayed with 3 hour history in the text-device..

Why not use ENTSO-E API

BartSr · Post by **BartSr** » Thursday 09 July 2026 12:32

Do you have info about it?

No worries, I wasn't feel attacked. I just clarified why I made the plugin.

The text file created by the plugin with all the json content you can simply disable in the devices tap (it will st work), the other text file filed with the data from the dzVents script was a quick script I've made as an example what maybe @Bartsr can use if he want.

I designed a new Day-Ahead Electricity Prices plugin and Claude coded it.

You can find it @ https://github.com/Poppinkpop/domoticz- ... rts-prices
It gets prices from energy-charts.info for 10 countries/bidding zones: Netherlands, Belgium, Germany-Luxembourg, France, Austria, Denmark West, Denmark East, Norway South, Poland, Spain. Add the hardware again with a different country to track more than one at once.

I installed it and it is running OK, but I see an error on the log:

Code: Select all

Error: dzVents: Method updateCustomSensor is not available for device "Enever Price Sensor" (deviceType=General, deviceSubType=Text). If you believe this is not correct, please report.

What does this mean?

That is an error from a dzvents script and not related to this plugin.

Right. I installed the code from the top of this topic, that throws the error.
