In Italy, energy sent to the grid is paid to a price proportional to the ENTSO-e price, that varies every 15 minutes.
Below an example (this is hourly price, actually price changes every 15 minutes)

The used energy price has a different type of cost: it may be

* change 3 ...

Hi.
I believe it will be very useful to have two electricity price devices:
1. imported electricity price : what we pay for each kWh from the grid. This price should be applied to all "usage" meters
2. exported electricity price : what we receive for each kWh to the grid. This price should be ...

Energy dashboard is really nice!
I'd also like to have more energy meters, and it should be nice to have another power source, for those who have two solar inverters or solar + wind.

I see that sometimes it works, sometimes it doesn't work.
I've got no data on 10, 14 and 15 December. Today it works here.

Thanks for your message. I read about the plugin. I never used any plugin. Is it just instaaling a plugin or does this also require any setting in the solaredge converter?

You just need to install the plugin, no need to configure the inverter. It uses ModbusTCP protocol to fetch data from the ...

You're right! Since 2 days it does not work, hoping the solaredge hardware can be fixed soon.
In the meanwhile, I suggest to install the domoticz-solaredge-modbustcp-plugin that permits you to fetch data directly from the inverter every 10s or less. API permits to get data every 5 minutes.

Wow, you have written many plugins!
You can register to the wiki and add them by yourself to the page https://wiki.domoticz.com/Integrations_and_Protocols

Also I suggest to add your plugins to
PPManager plugin https://wiki.domoticz.com/Python_Plugin_Manager
and
Domoticz Plugins Manager https ...

I’m using DomBusTracker2 to control the two motors of the solar tracker. It has wind protection, night and morning configurable positions, and can be monitored and controlled easily from Domoticz by using the available plugin.

Good to know a book exists. I believe it should be linked inside the www.domoticz.com website as like as Domoticz Wiki!

Description: very nice to have a notification when rain rate is greater than a threshold, but you have to divide the rate value by 100.
Actually, I set a notification for rain rate > 800 to have a notification when rain rate is greater than ...

My Inverter was installed in 2019, HD-wave SE6000H-RW000BNN4, has already the 11502 TCP port active.
I can stop the plugin, and telnet IPnumber 11502 and it works.
In the wiki page you mentioned it's written how to connect to your inverter by WiFi and enable the ModbusTCP port. I'm not sure that ...

I suggest to try the "Solaredge via LAN interface" already integrated in Domoticz (I didn't know about it), verify how it works and let us know replying in this forum.

You can also install the Python Plugin manager that permits to add new unofficial plugins for new hardware.
Have a nice day.

When you say "is not named in the Wiki" you should specify the URL of the wiki pages.
I'm using both plugins, the "SolarEdge via LAN interface" is better because you can get data every 10s (vI got it from https://github.com/addiejanssen/domoticz-solaredge-modbustcp-plugin ), while the plugin that ...

Your script can be called every minute, so you can use a variable to manage time to know what you have to do.

Please note you have also the "AFTER" keyword: I never tried, but maybe it works
commandArray[device]="On for 10 seconds after 7200 seconds"
Check it, it may not work as I expected.

Just one question : if the contact is "On" before the sequence, is this command will do the same or is it necessary to turn it off before ?

If it was on, you don't need to turn off than on for 10 seconds, but you may experience strange behaviours.

Try with this:
commandArray["stop_electrolyseur"] = "On FOR 10 seconds"

If it's easier for you (as for me), you can enable logging to a file, modifying /etc/init.d/domoticz* (if you're using Linux) and restarting domoticz.

To debug messages exchanged by MQTT, you can also subscribe to all topics by using the cmd (from linux shell)

Can you use a counter?
Selecting counter, then enter Utility panel and edit the new device, getting the following parameters that you can configure as you prefer.

Thanks for informing me about NL.
I understand: if you promise your citizens that all you produce in Summer you'll get back in Winter for free, you're doping the photovoltaic market!
We did the same in Italy in 2006-2012, with a very high revenew on each kWh produced (don't care if that energy is ...
