Daily grid consumption? Ambient temperature...

[peteDDD]

The one piece of data I am not finding in the Modbus protocol is the current daily grid consumption. Am I missing this somewhere? That would be the input that would be used in the red-circled area of this flow:

Also, to your experience, have you found the Ambient Temperature (temperd register 0x0223) reading to be anything logical? On my inverter, it always reads 120 deg C.

I wasn't able to find a relevant register that would provide a grid power value. To provide that information I simply created a template sensor on the ESPHome device that would compute the power value from the Grid Current and Grid Voltage. You'll see it in the YAML code, "id: srne_grid_power".

The temperature readings I get are fairly accurate. If you take a look at the YAML you see that it requires reading as signed int. What register are you pulling temp from?

This is what I've got right now...

Regarding "Ambient Temperature" here is the code on that. What temperature do you see when reading this value?

• platform: modbus_controller
  modbus_controller_id: srne1
  name: "Ambient Temperature" #name for HA
  id: srne_Temperd #id for HA
  register_type: holding
  address: 0x0223 #register address (see modbus manual)
  value_type: S_WORD
  state_class: measurement
  unit_of_measurement: "°C"
  accuracy_decimals: 2
  device_class: temperature
  filters:
  - multiply: 0.1

Re grid power... yes, I have the power number. I would like to get an accurate energy number (kwh) per day for the grid input. There are historical numbers but for some reason, no register for the current day. (that I can find) Very odd that this is the one value I can't find.

Another question... does the "reset machine" function just turn relock the machine (the opposite of the "Unlock Modbus Device" function? (I don't want to use it if it resets some of my other settings too...). (Currently, I can unlock the modbus but am not sure how to re-lock it).

THANKS AGAIN FOR YOUR GREAT WORK!
