no response from register_scan #23

Closed JanSchmidt3 closed 1 year ago

JanSchmidt3 commented 1 year ago

I enabled verbose output. For some registers the device seems to answer, but register_scan gives no output. What happens and how should I try to debug?

My device is a "SUN600G3-EU-230" with

Firmware version MW3_15U_5406_1.471

Scanning input registers

The Deye inverters respond only to read_holding_registers (function 0x03). Also the registers in the example here are too high. Try in the range(0, 700). Alternatively you can install the library I've been working on lately and use the deye-read command.
