Car domoticz project

[korniza]

As I use my car daily and a lot of hours behind the wheel, somehow I feel my car as a second home. I thought if someone has created a project dedicated to car. Attaching an odbII, reading news by voice, traffic notifications, emergency situation, even alarm & geofence can be part of this project.
So on basics, a ODBII interface required to communicate with domoticz. Well guys, hope there are other crazy guys like me to build this project.

Hi Korniza, I own a cheap OBDII > USB thing. I use an USB OTG cable to connect it to my Android phone. There are several apps that are able to use the connection. I personally use it for car diagnostics only. I have it in my car as standard, so that when I get a check engine light for example I can check if it's something I can drive home with or not. However it can give engine temperature information, consumption, RPM, speed and a lot more in real time. There are WIFI, Bluetooth and USB versions available. I have the USB version because the sample rate is higher and I don't want to screw around with batteries.

There are several projects you can see online. It's especially popular with people who replace their head unit with a tablet. They go all Fast and Furious with the dials on their dash and some replace their ECU with an aftermarket one so they can change maps on the go and whatever. Expensive hobby.

Anyways, these cheap OBDII dongles are generally ELM327: https://en.wikipedia.org/wiki/ELM327
A lot of info is available on this stuff online.

As I said, I only own a cheap 10 buck dongle, OBDLink is more expensive, but is generally considered to be better. I'm sure that with some programming knowledge you're able to make it work for what you want it to do.

I got 10€ ODB2 BT dongle + torque Android app.

On my syno a torque webserver ( https://github.com/econpy/torque
Using a syno you need to use mariadb and create db by hand)

Torque app send data to my server every time i finish a run.

Then a script update 2 devices on domoticz :
- % of fuel remain
- km left before empty

A cron update device 1 time a day

Of course you can get all device your car is able to provid via odb2.

I’m just new in Domoticz, and found this post.
I’m also intrested in reading the OBD statistics in Domoticz.

Somebody already started with this project?
I would really like to test...

Thanks.

Hi,

To what brand of car do you want to connect?
Some discussion has been started after my post.
See: viewtopic.php?f=38&t=26549

Hi,

I use a Kia Sportage, but I think the brand is irrellevant. Because OBD 2 is a standard for all cars after 1995.
I just bought a OBD2 Wifi key. It would be nice when the car is close at home, Domoticz could read-out the OBD info.
And while driving with the car, you could log information on your smartphone which you could upload in Domoticz when arriving home.

Thank you,

Pieter

Hi,

The reason of my question was that e.g. Home Assistamt supports several car brands out of the box.
And if it is possible with HA, it should also be possible with Domoticz. See my integration with Volvo.

For ODB2 a node exist for node-red. See: https://www.npmjs.com/package/obd2
Perhaps this is useful and with MQTT you can push it forward into Domoticz.

If this might be adapted to Domoticz you have to try. I see that most solutions use MQTT.

Best regards
