Energy meter Orno51x and modbus

Booster · February 27, 2020, 5:48pm

Hi,
I change platform from Openhab to Home Assistant, but my problem is to set energy meter orno 51x via modbus in HA,

In OH2 my cfg see like that

serial.home_freq.connection=/dev/ttyUSB0:9600:8:even:1:rtu:150:1000:none:none
serial.home_volt.connection=/dev/ttyUSB0:9600:8:even:1:rtu:150:1000:none:none

poll=5000
serial.home_freq.type=holding
serial.home_freq.id=1
serial.home_freq.start=20
serial.home_freq.length=2
serial.home_freq.valuetype=float32

serial.home_volt.type=holding
serial.home_volt.id=1
serial.home_volt.start=14
serial.home_volt.length=6
serial.home_volt.valuetype=float32

In HA i have only this

modbus:
  type: serial
  name: hub
  methos: rtu
  port: /dev/ttyUSB0
  baudrate: 9600
  stopbits: 1
  bytesize: 8
  parity: N

And error

Invalid config for [modbus]: [methos] is an invalid option for [modbus]. Check: modbus->modbus->0->methos. (See /config/configuration.yaml, line 261).

someone can help me finish the configuration so that I can get the data from the energymeter?

It should be method, not methos, as reported here: https://www.home-assistant.io/integrations/modbus/

Ok i change and now

I suggest you to test one data at a time.
Then, the example in modbus page does not leave blank lines.

atryda22 · March 19, 2021, 4:40pm

Hello Bartosz

Did you fixed your problem?
I have similar meter and similar problems
But at first you had the wrong parameter:
parity: N
It should be:
parity: E
“Even” just like you had in OH2 config.
But even after this setting, I still have a problem with reading the registers

regards

Alessandro_Lazzari · April 7, 2022, 12:08pm

has anyone been able to read the data from a three-phase orno?

Martijn45 · September 26, 2022, 10:50am

Hi,

I use a 3 phase Orno, model WE-517

For the communication I use a RS485-WiFI converter of Elfin (EW11A).

In Home Assistant I use the following lines to read the values of the energy meter.

Maybe you have something on the registerlist I use for this meter.
The “float” addresses work good, im only not sure about the non float addresses like the int16 / 32. I get some value but if its the right one I don’t know. Anyway I don’t need those myself.

spanky · September 26, 2022, 12:14pm

how did you find yourself? the reviews on Amazon are not good, both in terms of accuracy and with the count of the output current. can you tell me if the output current is displayed? I’m undecided between orno and eastron which costs twice as much. thank you

Martijn45 · September 26, 2022, 1:11pm

For me the price was the point to don’t take the Eastron but the Orno. If I would need just one meter I would had chose the Eastron. At home I needed 6 of them, and it did make a to big difference in price for me.

Why so many… My house is split-up in some apartments, a garage and a garden cabinet .

I know there are bad and good reviews on Amazon. Many reviews also go about the bad documentation and incomplete register list.

About the current, the measured current I see in the Modbus data, looks to me correct. But about the voltage I have my doubts. The measured voltage looks to me high and fluctuate allot. But its really good possible that the grid is here not stable. What is one of the reasons im investing in a storage system.
Anyway, the meters are MID certified, what should mean that the measured values should be acurate.

On the display of the meter is a lot info showed, but its not for all values clear what it is exactly.

The Modbus documentation on the site is not complete. And it did take me some time for me to figure out how to read it. If you transform the HEX addresses to DEC you get the right addresses and the Float on float32.

I still need to replace one kWh meter for a model with Modbus. That one is located directly behind the meter of the network operator. For that meter I will use a different brand/model, Victron EM24.

The Modbus data is store on two places.

for short therm use in Home Assistant
for long therm use in Influxdb with Telegraf. To analyse the usages over a long period.

Hope you have something on this info,

Kind regards,
Martin
