Pv systemen uitlezen met raspberry en domoticz.

[Jaconet]

Ik heb 2 Pv systemen mastervolt xs3200 en xs 2000. Deze wil ik uitlezen met raspberry en domoticz. Op de raspberry heb ik de p1 slimmemeter al werkend. Maar de 2 Pv systemen lukt me niet. RS485 -- RS 232 usb converteren op usb raspberry uitlezen lukt niet en ook niet zichtbare op domoticz. Graag sugesties Hoe ik dit kan oplossen of is dit niet mogelijk?

Original question in dutch, but rule of forum is to use english:
therefore reply in that language (although quoted URLs in dutch, because first/only found by my Google).

Which type of interface do you apply for read-out of your Mastervolt-inverters type xs3200 and xs 2000 by means of an adapter RS485<>USB?
See https://www.mastervolt.nl/producten/mas ... nterfaces/
Or this PC-Link which has capability to read all inverters on the RS485-bus?

Not very useful posts if you can't speak Dutch.

@Jaconet

To be expected that the PC-Link delivered by Mastervolt has interface-functionality included in the companion-software for PC, but that obviously is not a solution for your setup with Raspberry+Domoticz.

Looking in Domoticz' list of interfaces under Setup/Hardware, I don't see a specific choice for Mastervolt => no quick & easy integration
[but if somebody has better information ....]
Therefore 'Simple' connection of your Raspberry to the Mastervolts' RS485-bus-interface by means of a 'general' converter RS485<>USB probably will not work, and you have to find another solution.

Searching through Domoticz' Wiki & Forum and further on the Internet is first effort to possibly find a compatible script to load to a Raspberry with Domoticz.
If no result from that search (which would surprise me, considering the amount of Mastervolt inverters in operation), then a script needs to be developed:
- as basic interface-information you need to know the interface-protocol of the Mastervolts plus the identification information of each inverter.
- look around at the Domoticz forum for a script which can handle the RS485-interface plus the Mastervolt interface-info mentioned above plus the 'translation' to Domoticz
[several 'bits & pieces' availableat the Wiki & Forum which perform those functions:
e.g. look for other implementations of inverter-interfaces and for read-out of Energy-meters like DDS238-1ZN and Eastron SDC120
