USR-W630 IncompleteReadError #282

Closed swildig closed 6 months ago

Issue related to

Sunsynk / mbusd Home Assistant Add-On

Describe the issue/bug

I'm having trouble connecting to a sunsynk 8.8kw ECCO via a USR-W630. It doesn't even log the serial number from the inverter and every read errors with an "IncompleteReadError".

The inverter shows an ID of "01" so I've tried setting the "MODBUS_ID" to both 1 and "01" but neither seem to have any effect. I've also set READ_SENSOR_BATCH_SIZE to 8 as I've seen mentioned but that doesn't seem to help.

I've tried all 4 "Data Transfor Mode"s on the W630 and both inverter drivers in the addon.

I'm at a bit of a loss for what else to try, any help would be appreciated.

Just an update for anybody else reading this, after buying a simple USB RS485 adapter and running mbusd on a PI, I'm still unable to connect to an 8.8kW ECCO inverter over the RS485 port. Ran through the troubleshooting steps again now that I've ruled the gateway out and it turns out there's no voltage on the A/B pins from the inverter - last time I measured I neglected to unplug from the W630 which was pulling the voltage up.

For now using the RS232 port seems to be working okay.
