Additional Topics of CZ-NS4P
The extension board CZ-NS4P only connects to the main board using CN-CNT (and some Powersupply-Pins). So there has to be some additional commands like limiting power consumption (which is done by 0-10V Intervace on CZ-NS4P).
It would be awesome if this commands could be implementet in HeishaMon.
I hope CN-CNT-Bus is shared and all Commands of CZ-NS4P can also be sniffed on external CN-CNT-Connection, no need to intercept between CZ-NS4P and main board.
@seitfa we need user with cz-ns4p board and connection to pc via ttl-usb. I can provide all instructions how to do :)
If nobody already has cz-ns4p I'll buy one and resell it afterwards.
Are there any spezial requirements for the TTL Interface? I would have bought this one because of the housing and the abilitiy to switch voltage.
@seitfa plese remember about connecting/sniffing points. Since you are going to "borrow" CZ-NS4P it will be no good to solder anything on it. The easest way will be to use additional CN-NMODE connector on HP mainboard. ( in readme you can find siutable plug for it). You can also make a Y cable ,but i belive it is more time consuming. And this TTL interface what you linked is ok. And it will be great ,that for testing you will have either 7Pcs of NTC 10kOhm ( that's are easy to get) ,or at least 10kOhm resistors to simulate sensors.
@MiG-41 Any Ideas on running CZ-NS4P without a HP? (i currently don't own one)
Especially the powersupply seem not to be documented, just the connections to the mainboard.
Probably CZ-NS4P will need hex answers from HP. I'm not able to forseen i.e. what happen ,when CZ-NS4P will send a command to HP sending to set some particular temperature (i.e. Pool) , and not receive a proper answer... Teoretically it could be possible to set a Internet bridge You get command from CZ-NS4P ,and this command is sent to someones HP .... But that's needs to prepare some solution.
Hallo, ich habe eine CZ-NS4P, leider funktioniert die Kommunikation mit meinem Usb-232 TTL Converter nicht. Dieser funktioniert aber mit einen Arduino (softwareserial). Würde die Daten gerne bereitstellen.

Welche Unterstützung brauchst du um die Daten bereit zu stellen?
Hallo, habe einen 5kw Monoblock WH-MDC05H3E5. Ich wollte vorerst die Daten von der CN-CNT Schnittstelle mitloggen. Leider bekomme ich keine Daten von dort. Getestet mit einem USB-232 TTL Converter als auch mit einem Arduino Uno. Angeschlossen Pin 5 GND und Pin 2 TX CN-CNT so wie in der Beschreibung.

Please read all information!
Hello,
Has progress been made on this matter?
At the moment I understand that the power of the machine cannot be modulated in function of a photovoltaic solar installation, correct?
Regards
To be honest also CZ-NS4P is not doing this well.... In my opinion better to wrote some smart flow in node-red using frequency /power input signal and steering with temperature. Optional PCB is doing it finally in this way.
To find out all CZ-NS4P features somone needs to have it and make a full logs in all state of work.

Hello,
And with the 0-10 volt input that the machine has, you cannot modulate the nominal power?
For example, using an arduino-type microcontroller so that the voltage value varies according to photovoltaic surplus through a pwm output?
Yes you can , but you will be suprised , how this works . You give 0V ,and expecting that HP slow down to minimum (20Hz) ,but it doesn't , it is still around 40Hz , when the water temperature is lower then set. Maybe @gregor-samosir will describe it better , since that his opinion ( i was only able to test it - simulate CZ-NS4P via command , and observe the same).
So summarizing , still better to wrote smart integration and increse presset temperature when PV generates surplus.
Hello, I have the CZ-NS4P board, is it possible to read the data from the sensors connected to it?
Regards.
If you have the sensors connected to the PCB you have this temps in Heishamon. eg. TOP47, TOP48
