This description aims to document the data format that Hoymiles
|
||||||
die aktuellen Betriebsdaten der Wechselrichter auslesen.
|
micro inverters use to communicate their current operating state.
|
||||||
|
|
||||||
Ohne Umweg über die "Cloud".
|
The original Hoymiles setup requires connectivity to "the cloud",
|
||||||
|
see [this section below](#system-description).
|
||||||
|
|
||||||
|
With the information documented here, it is possible to interact with
|
||||||
|
a set of Hoymiles micro inverters in a purely "offline" way, i.e.
|
||||||
|
without requiring internet access or any connectivity to a "cloud".
|
||||||
|
|
||||||
|
The only required hardware is a Nordic "NRF24L01+" wireless module.
|
||||||
|
|
||||||
|
The `ahoy` project at [5] collects software for various platforms,
|
||||||
|
including Aduino and RaspberryPi.

The information in this document was gathered in a large community
|
||||||
|
effort which started out with [this post][1]
|
||||||
|
on the German [mikrocontroller.net][2] forum.
|
||||||
|
|
||||||
|
As of April 2022, this effort is still ongoing. Not all details have
|
||||||
|
been documented yet, and not all secrets have been uncovered.
|
||||||
|
|
||||||
|
Multiple members of the community have already successfully retrieved (and
|
||||||
|
continue to successfully retrieve) data from their Hoymiles micro inverters.

lautet die Shockburst-Zieladresse also (0x32, 0x88, 0x81, 0x72, 0x01).

- encode the final 8 digits of the serial number in BCD format:

`0x72, 0x81, 0x88, 0x32`

- reverse the order of the bytes:

`0x32, 0x88, 0x81, 0x72`

Initial protocol analysis focused on the data exchanged on link (C) in figure (3).
|
||||||
|
Not all the frames observed on this link will result in an actual RF transmission,
|
||||||
|
and some translation/mangling/processing happens inside the NRF24LE1E, in particular
|
||||||
|
|
||||||
|
- replacement of serial numbers
|
||||||
|
- recalculation of CRCs
|
||||||
|
|
||||||
|
These packets (which are all framed in 0x7e...0x7f bytes) are described in section
|
||||||
|
[Encapsulated Packets](#encapsulated-packets) below.
|
||||||
|
|
||||||
|
More recent efforts focus mainly on the actual "Enhanced Shockburst" packets
|
||||||
|
that are transmitted over the air. These packets are described in section
|
||||||
|
[Enhanced Shockburst Payloads](#Enhanced-Shockburst-Payloads), and the
|
||||||
|
information contained in this section is more up to date.

Enhanced Shockburst Payloads
|
||||||
|
----------------------------
|
||||||
|
|
||||||
|
- These are the packets that are exchanged between inverters and DTU via the Nordic
|
||||||
|
"Enhanced Shockburst" protocol.
|
||||||
|
- Each payload is preceded by a preamble, and terminated by a 16-bit CRC, as described
|
||||||
|
in the [Nordic datasheet][3]. See also figure 4 above.

|

|
- This message will cause the inverter to transmit a CMD=0x01, CMD=0x02, and, occasionally, also a CMD=0x83 message
|
||||||
|
to the DTU with serial number DTU_SER#.
|
||||||
|
- Values of "0xb0, 0x00" and "0x11, 0x00" have been observed for "UK1". Their meaning is unknown.
|
||||||
|
- "SEQ" was observed to contain increasing numbers when sent by a Hoymiles DTU. In particular,
|
||||||
|
each issued "command" (e.g. "switch inverter on", "switch inverter off") appears to increase this
|
||||||
|
value. A constant value of 0x0000 or 0x0005 appears to work just fine.
|
||||||
|
- Repeatedly sending the same TIME information (instead of correctly increasing time)

[has been shown](https://www.mikrocontroller.net/topic/525778?page=2#7021386) to result

in identical behaviour, the inverter still replies as described above.
