It is working, but....

[MBj1703]

Got my board today and just tried it. It is working in general.

I got the MQTT Topics into my Smarthome:

Now I would like to "translate" this information in readable format.
Therefore I would to like to know, what the different topics mean.

Something like: updatedRegister_data_1 48 = Batterie at 48%

Also I would like to know, how to send.
From the example I can see this JSON:
{
"requests" : [
{
"updateRegister" : {
"register" : 2,
"value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]
}
},
{
"operation" : {
"airCon" : "on"
}
}
]
}

turns on cooling for 10 minutes.
So what are the other commands?

Also here a "translation table" would be helpful.

Thanks a lot!

I don't actually have the car anymore so I can't really test any of this, however to explain...

The reason it kinda works only some of the time it due to the way the code handles the encryption of the payloads, I never figured out a way to get the keys 100% of the time, but the car leaks the current key which is then used to send commends.
If you get lucky it will work, but there's also a retry mechanism to get around the fact some of the commands fail.

the register 2 is to control the timer and the heat mode, if I recall the 7th byte is the mode, first 4 bits are the time and second 4 bits are the mode, you can see the definitions here

https://github.com/phev-remote/phevcore/blob/57d89c2d9dd175eba613d74ce856aa5f766dbb50/include/phev.h#L87

[MBj1703]

Ok, thank you. It is a beginning :-)

If I look on your code I found this

`switch(time)
{
case T10MIN: val |= 0; break;
case T20MIN: val |= 16; break;
case T30MIN: val |= 32; break;
}

uint8_t data[] = {0, 0, 255, 255, 255, 255, val, 255, 255, 255, 255, 255, 255, 255, 255};`

So 10 Minutes would add 0 on number 7 = {0, 0, 255, 255, 255, 255, 0, 255, 255, 255, 255, 255, 255, 255, 255}

But this doesn't fit with the example saying 10 Minutes: [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]

[MBj1703]

I think the timing stuff is clear.

{ "operation":{"airCon":"on"} turns on AC.
How can I send heat?
I can find this in the code.

[papawattu]

This command sets the mode, then use the aircon on to switch it on.

{
"updateRegister" : {
"register" : 2,
"value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]
}

[MBj1703]

Now I total confused.

"value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]
What does it set exactly? On the main page is written: The command above sets the aircon to ten minute cool.
With the exact same value??

Sorry if I'm stressing with all my question. Just learning... :-)

[MBj1703]

I just started the board in the car and receiving MQTT topics.

When I send

{ "requests" : [ { "updateRegister" : { "register" : 2, "value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255] } }, { "operation" : { "airCon" : "on" } } ] }

nothing happens.

Has anyone got this working?

[papawattu]

"value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]

The only value that matters is in bold.

so its set to 1 above which means 10 mins heat

1= HEAT
and then logic OR with the time 0 which is 10 mins

[MBj1703]

okay, thanks, understood.
But unfortunately, not working.

In the meantime, I got additional readings (which is cool):
`

status_battery_soc	94	2021-02-17 21:48:09
status_dateSync	2021-02-17T20:51:56Z	2021-02-17 21:52:21
status_hvac_mode	2	2021-02-17 21:48:09
status_hvac_operating	false	2021-02-17 21:48:09
status_hvac_time	2	2021-02-17 21:48:09

`

But what is HVAC Mode and Time?

[papawattu]

30 mins cool

NONE = 0
HEAT = 1
COOL = 2
WINDSCREEN =3

10MIN = 0
20MIN = 1
30MIN =2

[MBj1703]

Yes it is cooling, that's why it goes to "false".

I'm still struggling sending HEAT.

[runestone74]

I change the mode from the official app and then change from heat to cool twice a year :) I just send the start HVAC command ons 17 feb. 2021 kl. 22:03 skrev MBj1703 <[email protected]>:

But what is this command?

The JSON what papawattu said is not working:

`"value" : [0,0,255,255,255,255,1,255,255,255,255,255,255,255,255]

[MBj1703]

I changed my MQTT server and now I can see something comming in.

When I send to the ESP, I can see the following in the monitor:

I (27053) PHEV_SERVICE: Phev message command F6 reg 02 type 00 length 0F
I (27053) PHEV_SERVICE: Sending air con on command
I (27053) PHEV_SERVICE: Phev message command F6 reg 04 type 00 length 01

So looks like it receive something, but nothing happens?

[MBj1703]

Today, after testing around, heating started once.
Since then, never again :-(

The connection in general is really fragile. The ESP is restarting often.
For me it looks like you need to hit the exact point in time to make the command working.

Also hvac_mode and time are not changing. Both are always 2, like mode are false, even if the heating is starting by schedule.

Here are more logs when sending:

I (44983) MQTT: MQTT_EVENT_DATA
I (44983) PHEV_SERVICE: Phev message command F6 reg 02 type 00 length 0F
I (44993) PHEV_SERVICE: Sending air con on command
I (44993) PHEV_SERVICE: Phev message command F6 reg 04 type 00 length 01
E (51593) PHEV_CORE: Unknown encoded command 79 or 78
E (52523) PHEV_CORE: Unknown encoded command 26 or 27
E (52523) PHEV_PIPE: Could not extract message

[MBj1703]

Today I played again and got the heating working...just 1 time....
The module is dropping a lot of errors and rebooting every 3 minutes.
