Im Anhang ist ein ZIP die du in NodeRed importieren kannst.
IPs VIs User/Pass anpassen und dann sollte es gehen.
Ich kann auch ein kleines Plugin für den Loxberry schreiben wenn du nicht extra Node-Red installieren willst.

hismastersvoice nur aus Interesse warum verwendest du nicht das node-red-contrib-loxone. Gibt es hier vor oder Nachteile?
Hatte gar nicht gewusst das man auf dem Miniserver per http im Sekunden takt schreuben kannKommentar

Hab einen herkömmlichen Heizstab mit Sicherheitstemperaturbegrenzer und einen Chiemtronic 3phasen 0-10V Schwingungspaketsteuerung.
T-Drive 3Ph compact - Chiemtronic
Je nach Leistung muss das Ding auch TAB/TAEV tauglich sein damit du kein Problem mit deinem Netzbetreiber bekommst.
I use same T-Drive from Chiemtronic:
1) Did you installed some EMI filter at the input stage ?
2) Also, do you protect the T-drive with fuses or via magnet-breaker ?Kommentar

To reduce lime scale problem, I installed a 9 kW e-cartridge and I'm driving it no more than 50% (I have a 6 KW PV on the roof). In this way I can get a quite low power density (W/cm2) on the cartridge, this helps working longer before cleaning it.Zuletzt geändert von Pippo74; 25.09.2022, 07:38.Kommentar

Yes if your 9 kW e-element has the same power density (W/cm2) of a 4 kW element...
In practice wirh 9 kW I have double the cartridge surface... and I can do lime-scale cleaning one times less compared to a 4 kW element. J
I mean it's a simple trick with more or less same cost between the two cartridges.Zuletzt geändert von Pippo74; 27.09.2022, 08:33.Kommentar

Dear AlexAn
Are u always using Thyristorsteller for boiler & PV eccess ?
I'm now facing two main issues:
1) Chiemtronic thyristor unit have a quite high stand-by power, I measured about 3 W 1phase, 5 W for the 3 phases.
Since I also have another 2 x 1p Chiemtronic units to warm the towel/heaters. So 3 + 3 + 5 it's about 11W on top of my already high stand by...
I then believe will always enable them (terminals 1 and 2 in short) and will use a power relay to enable then just in case of sufficient PV power, say P>200 W.
2) From the time I use 3p-12A thyristor to drive my 9kW e-cartrdige I've noticed a mismatch between the energy consumption given by my Fronius energy meter and the Energy-company fiscal one. In details I've seen a difference of about 30 % higher from the official meter !!!!
How this is possibile ?
In theory Fronius Smartmeter has a 4096 Hz sample rate, so that I should not loose any energy even at low rate thyristor driving....
I'd like to get your valuable feedback.
Thanks a lot.Kommentar

Den Leistungssteller schalte ich erst per Schütz frei wenn ich ihn tatsächliche nutze und von daher habe ich die Standby Verluste nicht.
Die Regelung mache ich mit dem Zähler des Netzbetreibers und nicht mit dem Fronius Zähler der da eventuell ein Problem haben könnte da er auch die Messklasse 2 hat und nicht Messklasse 1 wie der vom Netzbetreiber.
Welchen Leistungsteller hast du? Wellenpaket oder Phasenanschnitt?
Der Fronius Ohmpilot von meinem Bruder macht das ganz sauber:

Thanks Alex!
Wow, this sound to be the perfection :-) Don't actually know if Ohmpilot has the same principle as the Chiemtronic.
I have all models "Schwingungspaket"
Today I've also powered the thyristors with a contactor, and shorted pins 1 and 2 to always have the unit enabled when powered.
About the meter, unfortunately the Class 1 from the grid is not close to my Loxone cabinet, since it's close to the external fence of my house at about 20 m. Which way are you reading it ? Via IR and Loxone Air ?
Anyway there must be something wrong, or not properly calculated, from the Fronius Smartmeter... I have it located as feed-in, so on top of all other Loads from the house & inverter Gen24.
Kind regards.

Lese mit dem Zählerinterface von Loxone aus aber Tasmota geht genauso.
Dein Fronius Smartmeter dürfte ein bekanntes Problem haben - Austausch veranlassen wenn möglich:

Yep, Thanks I read the Fronius issue.
They recently work with a new Energy meter which is the TS-65A-3 (Gavazzi re-branded) instead of the usual 63A-3 (IME re-branded which I have)
The new Fronius Energy meter claims to read with a Frequency of 4096 samples / second, which is more than sufficient to read power coming from a burst-fireing thyristor controller.
If I had a phase-cut thyrystor it would be possible to have EMI issues or harmonics, but with the burst-firing not, since it's a zero crossing technique.
Now I've another counter (new off the shelf, never been used. J) from Algodue company (it seems it Italy we have many energy meter manufacturers !), will put this in series of the Fronius to get a 1:1 comparison...
About the Ohmpilot:
1- Time to close the loop, reading - reacting, is way shorter than passing via Modbus TCP from Loxone + Preparation time of the Energy Manager which takes away another 30s, which is a life !
2- Interesting to know which kind of controller it's: thyristor with burst-firing too ?Zuletzt geändert von Pippo74; 28.05.2023, 22:26. -
Ob und welcher Zähler das tatsächlich richtig erfasst kannst nur du mit einer Referenzmessung klären!
Hatte den Chiemtronic vor der 5sec Modbus Grenze schon eingebaut und damals hatte ich Probleme mit einem Schwingen der Leistungen und Auswirkungen auf andere geregelte Lasten wenn ich zu schnell geregelt habe. Von daher halte ich die Berechnung je 1Minute schon für OK auch wenn es auf den 1.Blick zu langsam erscheint. Bei einem Elektroauto/Wallbox möchte ich auch nicht alle 5sec die Werte ändern. Im Solarweb wirst du das gar nicht richtig merken.

Yes, I see, thanks !
I see you have a 10 kW PV, what about the EHZ in the boiler ?
- my PV is 6.3 kWp, with a Symo Gen24Plus 6.0
- Resistor of the boiler is 9 kW (I got it so big in order to reduce the surface Kalk), so with maximum ideal situation I drive the Thyristor at 50% to cover my surplus of 4...5 kW.
That means when I drive the resistor at 50%, only 25 full cycles (the half of 50 Hz) are driven in a second, and in that time the resistor is anyway driven at 9 kW, that means 4.5 kW from PV + another 4.5 kW from the grid... which are possibly the ones calculated from my supplier, but probably not from the Energy meter :-)
I believe I should then replace the resistor with a smaller resistor, maybe 3 or max. 4 kW. (and who cares about cleaning it frequenly... because I have 13 °D Kalc). This, in order to have the P of the resistor within my maximum PV excess.
p.s. U right about the E-car charging, is even no good to connect/disconnect the car once in a minute, that's why for the wallbox I just care about the current PV available power (not excess !), and if it's at least 1.5 kW I won't stop/hold the charge.Zuletzt geändert von Pippo74; 29.05.2023, 10:37.

Dear AlexAn
- Do u have Phasenanschnitt thyristors or schwingungspaket ? It maybe with Phasenanschnitt should be able to better control the power without spikes taking current from the Grid. I choose schwingungspaket because they said it's better for controlling resistors avoiding conducted radiations, harnonics etc.
- which power size is your resistor ?Kommentar
