Some ideas?

                                const deviceClassId = data.buffer.slice(0, 4).readUInt32BE();
                               ^
TypeError: Cannot read properties of undefined (reading 'buffer')

☝️ Looking at the relevant code:

            // Read device class (U32, ENUM).
            client.readHoldingRegisters(30051, 4, function(err, data) {
                const deviceClassId = data.buffer.slice(0, 4).readUInt32BE();
                deviceType = data.buffer.slice(4, 8).readUInt32BE();
                deviceClass = SMA_DEVICE_CLASSES.get(deviceClassId) || `unknown ${deviceClassId}`;
                registerInverterDiscoveryIfComplete();
            }.bind(this));

That's blindly reading data and is ignoring err altogether 😬 This is one of the last remaining patterns of code remaining of the original codebase that I forked from (https://github.com/codyc1515/homebridge-sma-inverter).

Question: Modbus TCP/IP is enabled?

funx1 commented 6 months ago

TCP is active on the STP and SBS. Actually I can access the SBS from the HA SMA implementation but not the STP. But I was able to access values over iobroker and modus.

Actually I can access the SBS from the HA SMA implementation

Last time I looked, the Home Assistant integration was scraping the inverter's web UI 😨

But I was able to access values over iobroker and modus.

How does iobroker get the data? And what is "modus"?

funx1 commented 5 months ago

I give up on this. Using now HA with modbus to read out values. Integrations I tried did not work. Previously with iobroker I was using modbus too. After switching to homebridge I lost these values. But I will start reading them with modbus again.
