Smart Meter Deye MR1-D5-W: Error when trying to add

[benoitfouc]

Description

Hello there, i recently buy a Smart Meter Deye MR1-D5-W in order to see my electricity consumption and give some directives to my IZY POWER TITAN 2400 batterye (charging or decharging).

But using the Solarman integration on my Home Assistant, i can't add the smart meter (and the battery) correctly.
I connect them to my "Solarman" android APP (and "Energy ease" app, the new version of Solarman APP including batteries) correctly.

Reproduction Steps

Go to the Solarman integration into the HA
Add a new device
Put the IP adress of the smart meter
Add the device

Hi @benoitfouc, support for this device is not implemented because we do not have Modbus RTU documentation. Try contacting Deye support and asking about it and maybe we can do something about it.

Hello there @davidrapan, the support send me the files per email, i will try to attach them to this message. If you need anything else let me know, my ticket is still open with the Deye's support

Can you show me device detail page from Solarman/Deye Cloud? So I can try to find relevant registers?

[davidrapan]

And try to configure the device using this small PoC custom profile and let me know:

info:
  manufacturer: Deye
  model: Smart Meter

default:
  update_interval: 60
  digits: 6

  - group: Info

I'm sorry i don't find this by myself. The deye support send me that, but looking to the SN, it's my inverter, not le Smart Meter.

And try to configure the device using this small PoC custom profile and let me know:

info:
manufacturer: Deye
model: Smart Meter

default:
update_interval: 60
digits: 6

parameters:

• group: Info
  update_interval: 3600
  items:
  • name: "Device"
    class: "enum"
    rule: 1
    registers: [0x0000]
    icon: "mdi:information"
    lookup:
    • key: 0x0000
      value: "Unknown"
    • key: 0x0103
      value: "Off-Grid Inverter"
    • key: [0x0002, 0x0200]
      value: "String Inverter"
    • key: [0x0003, 0x0300]
      value: "Single-Phase Hybrid Inverter"
    • key: [0x0004, 0x0400]
      value: "Microinverter"
    • key: [0x0005, 0x0500]
      value: "LV 3-Phase Hybrid Inverter"
    • key: 0x0006
      value: "HV 3-Phase Hybrid Inverter"
    • key: [0x0007, 0x0600]
      value: "HV 3-Phase Inverter 6-15kw"
    • key: [0x0008, 0x0601]
      value: "HV 3-Phase Inverter 20-50kw"

I do that and i have an error "Cannot open connection" so i check the network configuration of the SM, all seems to be good.
I ask to the support and they tell that's normal because "I have consulted with the pre-sales engineer, and his response is that Solarman currently does not use this 8080 feature externally and does not support your local API"

So, i think, it's gonna be complicated to implement this SM right ?...
