All M+M commands are sent to ID 0x69D

Connect M+M

At initial connect, two commands are sent. This example was run on on Nov 07 15:45:45:

24 50 15 0b 07 

15 0b 07 is the date: 0x15 = 21 0x0b = 11 0x07 = 7

24 51 0e 2d 00 

0e 2d is the time: 0x0e = 14(+1) 0x2d = 45

Additional 69D commands seen at M+M connect:

Nov 08 11:39:57 80 04 19 59 11 00 00 04
Nov 08 11:39:57 80 04 19 5a 11 00 00 04

Modify Charge Current

Modification of immediate charge current ("Sofortladen") leads to four different commands:

80 14 29 59 13 45 00 01
c0 00 02 00 0a 00 00 00
c1 08 4f 70 74 69 6f 6e
c2 65 6e

In details:

80 14 29 59 13 45 00 01

80 14 is possibly the command indicator,
59 (fixed ?),
13 is a counter that's incremented for each packet,
45 00 01 (fixed ?)

c0 00 02 00 0a 00 00 00

c0 (and c1, c2) are additional parameters for the initial 80 command
02 seems to be "climate w/o batt only" (06 is with batt)
0a is the current parameter (10A - other values: 0x0d=13A, 0x05=5A, 0x20=max)

c1 08 4f 70 74 69 6f 6e

(no details known yet)

c2 65 6e

(no details known yet)

c1 and c2 contain the same data as in the 69E c2/c3 OCU commands for climate control (see end of this text):

C2 1E 1E 0A 00 00 08 4F
C3 70 74 69 6F 6E 65 6E

Seen commands:

Nov 07 15:53:01 c0 00 02 00 20 5a 5f 00  # 0x5a = 90
Nov 07 15:53:01 c1 00 1e 0a

Climate timer 1 to Sunday, no repetition

Nov 06 14:45:31 80 08 29 54 15 0b 07 0c # Sunday is 2021-11-07, i.e. 15 0b 07; 0c is hour-1
Nov 06 14:45:31 c0 32 81 03 00 # 32 is minute; 81 is 0x80 (sunday) | 1 (no repeat)

Activate timer 3 (1 & 2 already active)

Nov 06 14:47:01 29 53 07 00 -> 7 is 1 | 2 | 4

OCU commands climate on

(taken from OVMS source) 5A7 60 16 00 00 00 00 00 00

69E 80 20 29 59 21 00 00 01
69E C0 06 00 10 1E FF FF 00
69E C1 FF FF FF FF 01 78 00 # 78 = 22 deg
69E C2 1E 1E 0A 00 00 08 4F
69E C3 70 74 69 6F 6E 65 6E

5A7 60 16 00 00 00 00 00 00

69E 29 58 00 01 # 01 = on, 00 = off?

These OCU commands seem to have an effect on the following parameters:

• min. SOC to 30% (0x1E?)
• charge current to 5A (?)
• 22 deg (0x78) climate with battery (06?)
• start climate now
