All connected but no data

[yvansandoz]

D1 mini configuration and wiring all good. In HA, the device is recognised and provides 10 entities with data value "unknown". My meter is a Iskra AM550 and I am in Switzerland.

Where should I start to look for a solution?

You could connect to that esp directly (telnet/netcat to port 23) and see what's coming in.

Also, make sure the default baudrate matches your specific smart meter.

I'm guessing the IP address is not the one assigned to the esp. you wouldn't need to do anything with portforwarding, assuming home assistant is on the same network.

I reach the limits of my knowledge... I did play with my router to open the port 23, looked for any other possibilities, but I always get:

That doesn't look good. I have some code in the repo to try out different baud rates, but not sure if that would help.

This is not my area of expertise.

Those are the parameters of my Iskra AM550:

General characteristics

• Connector: RJ12 on the upper right side of the meter, labeled "P1 interface
• Interface: according to P1 DSMR V5.0
• Protocol: DLMS/COSEM
• Payload length per frame: 154 bytes Configuration of the counter interface
• 115200bds
• 8 bits
• No parity
• 1 stop bit Data transmitted in DLMS The data are transmitted by Push mode every 5 seconds.

[DavyLandman]

Things you could try:

• Replacing the 10k Ohm resistor with either 1k or 3.3k
• change SERIAL_BITS to SERIAL_7N1 and see if that works?

otherwise: no idea, I've looked at posts on the internet, more people have been able to read that AM550 P1 port without problems.
