But can you give me specific addresses you tested so I know which doesn't work?
Can you repost here screenshots of your whole sensor list? And also some screenshots of your Solarman App? Which profile are you currently using?
Yes it looks like that register is invalid for your device. Can you also list all sensors which works? (Shows correct value) It’s really hard to tell just from screenshots,...
Can you give me full output of Developer tools >> ACTIONS >> Solarman: Read Holding Registers (Modbus Function Code 3)? * Select your device * Register set to 1600 *...
Can you try it w/ some other values in ranges? * 1600 -1700 * 20 - 125
Can you continue probe the range between 1600 - 1700?
But the profile reads some registers from 1680-1700 range so some has to work. I just wanted to see others in their proximity...
It's very easy, just do multiple separate requests w/ following parameters: * Register: 1620, quantity: 20 * Register: 1640, quantity: 20 * Register: 1660, quantity: 20 * Register: 1680, quantity:...
Mhhh a lot of zeroes.. this address space should contain values for Energy Import/Export, etc. 😕 So another possible way to find out which registers holds these values is to...
That's not what i mean. It has nothing to do w/ modbus directly but sniffing traffic using wireshark (tcpdump) and MITM between inverter and the internet. 😉
