Domoticz on Synology NAS with P1 USB interface gives no data from ISKRA MT382

Synology NAS DS716+II with DSM 6.2.2-24922 with Domoticz 4.10717 from www.jadahl.com
Installed NAS USB drivers: UsbSerialDrivers_braswell-6.2_6-4.spk (all latest versions)
P1 cable: FTDI USB TTL RJ11 6P4C Cable For Iskra ME382 EN MT382 P1 Port Dutch Slimme Meter Cable
At home (Dutch): "My" Slimme meter: ISKRA type MT382[/b]
Domoticz: hardware Slimmemeter with “P1 Smart Meter USB” (@default)port: /dev/ttyUSB0 9600 Baud
Domoticz: installed “apparaat” : actually tried almost all meters, no one gives data.

Problem: meters do not display any data, however: communication with “slimme meter"works, looking in Log Domoticz it also found the connected Gas meter, so I assume communications does work.

Already tried: (found some forum data, in case “what to do”:
Access (chmod777) USB driver: /dev/ttyUSB0 (with PuTTY with ROOT login by sudo –i)
Access (chmod777) to /volume1/@appstore/domoticz/rules.d
I looked for the connected USB ports and devices with: lsusb (with PuTTY): root@NAS/etc# lsusb
>Bus 003 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

However: in Domoticz, when I stop and start again the hardware “P1 Smart Meter USB”,
And if I look into the Domoticz log / status, I find:
2019-05-30 11:46:56.656 Status: P1 Smart Meter: Worker stopped...
2019-05-30 11:46:59.534 Status: P1 Smart Meter: Using serial port: /dev/ttyUSB0
2019-05-30 11:46:59.552 Status: P1 Smart Meter: Worker started...
2019-05-30 11:47:09.183 Status: P1 Smart Meter: Found gas meter on M-Bus channel
2019-05-30 11:47:09.320 Status: P1 Smart Meter: Meter is pre DSMR 4.0 - using DSMR 2.2 compatibility

So there is communication with the P1 bus, but all Domoticz "Apparaten" show no data.
Perhaps the Jadahl version for Synology only supports 8bits P1 meters?I saw that the ISKRA MT382 uses 7 bits.

Can anyone give me a hint?

All thanks for the input; the error was completely on my side.
With Domoticz, I used to work with Sonoff and Tasmota, and there you create a Dummy Hardware, and from that one you create a virtual sensor. I did the same with the P1 meter, but that is useless.
On the page Equipment (Apparaten), under the tab -All Equipment- (Alle Apparaten) I foud the working P1 hardware. Piece of cake....
