I have that add on. I had previously read that it doesnāt connect to Home Manager. I just installed the beta version and no - doesnāt connect to home manager 2.0

Do you have a switch in between or something similar, because normally the device should appear in your router. Sometimes the devices are a bit stubborn. I would try unplugging the device and plugging it back in or resetting it. I know this from the HM1, where I suddenly had problems with the connection for inexplicable reasons.
I can see the device in the router (unifi network) but I canāt navigate to the device through IP.
Have you looked at the links I gave you or described your problem in the forum? Unfortunately, I can only recommend that because I no longer use SMA.
As already described, I also had problems even though I had been using the device for several years.
I am using the SMA Energy Meter Add-On to read data from my SMA Home Manager 2 - and it (nearly) works great through the Mosquitto MQTT broker into my Raspberry Pi 4-based Home Assistant.
My only problem with it is I get āspikesā of high power on āpconsumeā every 30 minutes (+/1 one minute) (which can affect my integral to kWh). The spikes on āpconsumeā come from spikes on āp2consumeā (but p1consume and p3 consume are fine).
As you can see below, there are spikes on p2consume - but u2 and i2 are fine. I canāt imagine the Home Manager is making a computational error - but Iāve no idea where the problem can be occuring.
I can start dreaming of ways to filter the spikes out, but of course, it would be better to eliminate them at the source.
Anyone have any ideas ?

Hello,
Iām trying to create an Esp/Tasmota based emulation of an SMA meter. My cabinet is full and I already have all necessary info from the P1 port of the utility meter. I found several examples of such an emulation and based my implementation on those. However my inverter still indicates faulty communication for the speedwire meter. Can somebody post a hex dump of a udp packet of an actual SMA meter. That would be of great help.
I already found a solution, thanks to the excellent speedwire library at GitHub - RalfOGit/sma-emeter-simulator: An SMA(TM) emeter simulator written in C++.
just fyi, i had a lot of problems with the sma integrations but the follow integration (HACS) solved all my problems : GitHub - littleyoda/ha-pysmaplus: home assistant custom integration for pysma-plus also the Home Manager is now working perfectly without modbus etc.
The update that occurred yeterday has broken my SMA Energy Meter. Even with the watchdog turned-on, the add-on stops within a minute or 2 of being restarted. The MQTT data gets updated, but then the logs show this:
00:12:50 INFO - p3supply every 60s
00:12:50 INFO - cosphi every 60s
00:12:52 WARNING Unknown SMA serial number 4294967295. If you want to use this device,please add SERIAL_NR and HA_PREFIX to SMA_DEVICES

The unknown SMA serial number changes each occurrence - I donāt have any devices with numbers anywhere near that large.
MQTT is certainly still active - MQTT Explorer shows other devices still updating.
Where can I find the previous version of the add-on to install ?
