Hello everyone,
my energy meter is running very well with ESPHome and the modbus configuration.
The adress which I have to reset is:
And the value to write is 0
function code 16 (0x10)
here my code which is not working:

Hi, you may want to take a look at the great work @rodgon81 has done (esphome/esphome/components/dxs238xw at dev · rodgon81/esphome · GitHub ). His integration has an action to reset the total energy. I have used it and it has reset the meter counter on my DDS238-4 W.
Regards
Done with this code for my DDS238-2 ZN/S:
switch:
- platform: modbus_controller
modbus_controller_id: rs485
name: "Reset command"
id: reset_partial
register_type: holding
address: 0
write_lambda: |-
ESP_LOGD("main","Modbus Switch incoming state = %f",x);
// return false ; // use this to just change the value
payload.push_back(0x04); // device address!
payload.push_back(0x10);
payload.push_back(0x00);
payload.push_back(0x00);
payload.push_back(0x00);
payload.push_back(0x02);
payload.push_back(0x04);
payload.push_back(0x00);
payload.push_back(0x00);
payload.push_back(0x00);
payload.push_back(0x00);
payload.push_back(0xe2);
payload.push_back(0x63);
return true;
Thank you for this hack.@martin8310

How do you handle Low and High registers for calculations. For example: In many GitHub examples, Total Current Energy = Current Enery Low + Current Energy High. I don’t know if I’m adding them correctly
- platform: template
name: "Current Total Energy"
unit_of_measurement: "KW"
lambda: |-
return (id(Energy_Low).state + id(Energy_High).state);
Thank you all
