[SOLVED] Mysensors nodes are not updating

Configuration
21

Update: Based on the advise of @firstof9 I started with setting up a new gateway with 2.3.0. As my original gateway was based on an Arduino Nano with a W5100 ethernet shield, I decided to go for a RPi now. After it was setup, I switched over to the RPi and connected it to HA (changed the IP adres in HA). What a diffrence this makes! The RPi took over seamless. Both sensors are now attached to the new gateway. HA is showing updates without any interuptions. So the only conclusion I can come up with is is that the Arduino gateway, or more specific the W5100 is the problem. The RPi feels more stable and is a solid entity in my home network (has a proper MAC for example). So for now the Arduino gateway is retired and the RPi is the new gateway. @firstof9: thanks for your support. You pointed me in the right direction andhelped me deduct to the root cause.

Problem solved!

To be fair I use an Adafruit Feather M0 with RFM96 radio as a gateway works fine, I use their W5500 (i think it’s that I’d have to check) ethernet wing and use a PoE splitter to power it.

Glad you got your’s fixed!

I know this is an old thread but I thought I’d post what I believe is the issue in case anyone else has a similar issue. The W5100 Ethernet gateway can only have one controller connected to it. So, connecting the MYScontroller and Home Assistant at the same time will cause issues. If you need more connections you can use SOCAT and Node-Red. That’s what I do and it has been working great for years.
