I am looking for help to connect an Orno meter to a Huawei inverter. Both devices have an RS 485 link, and when the devices are connected together the inverter does not see the meter. The original monitoring is built on a DTSU 666H, it also has an RS port

. And only with such a meter can it get along. A counter is not equal to a counter, a question of register addressing. You do not lose much, the information from the counter is not necessary for the inverter to operate, it only adds statistics to the cloud. If you are stubborn, you can make your own statistics, but this requires setting up a server of some kind.
