This adapter can listen to this communication and extract many useful information. The often used energy meter E380 CA is also supported. -Important parts are based on the project [open3e](https://github.com/abnoname/open3e). -A python based implementation using MQTT messaging is also availabe, see [E3onCAN](https://github.com/MyHomeMyData/E3onCAN). +In parallel UDSonCAN service ReadByDid is supported.

Next step will be to implement services readByDid and writeByDid according to UDSonCAN protocol. Then, same functionality as with open3e will be available. +Important parts are based on the project [open3e](https://github.com/open3e). + +A python based implementation of a pure listening approach using MQTT messaging is also availabe, see [E3onCAN](https://github.com/MyHomeMyData/E3onCAN). + +**Present implementation is restricted on listening and reading via UDSonCAN (ReadByDid).** One of next steps will be implemention of UDSonCAN service WriteByDid. + +During first start of adapter instance a device scan will be done providing a list of all available devices for configuration dialog. + +# Getting started + +**Preconditions:** +* You have a (USB to) CAN bus adapter connected to external CAN bus of Viessmann E3 device +* CAN adapter is up and visible in system, e.g. as "can0" (use ifconfig to check) +* Refer to open3e project for further details + +All services provided by this adapter are based on device list of your specific Viessmann E3 setup.

This step is **mandatory**. The instance will restart, connect to the CAN adapter and do a scan for devices available on bus. **Please be patient** - this may take 10 to 20 seconds. You may watch the activities in a 2nd browser tab by looking on the logging info of the adapter. +* When scan was successfull two new tabs will get visible in adapter confuration: "LIST OF UDS DEVICES" and "ASSIGNMENTS TO EXTERNAL CAN ADAPTER". +* Go to the "LIST OF UDS DEVICES" and check the list of devices. You may change the naming on 2nd column. Those names will be used to store all collected data in ioBoker's object tree. Again press "SAVE" button when you did your changes. Again this step is **mandatory**. +* Instance will restart again and after a few seconds you are ready to configure schedules for collecting data on tab "ASSIGNMENTS TO EXTERNAL CAN ADAPTER". +* For **energy meter E380** (if available in your setup) you just can activate or not. Please notice the value "Min. update time (s)". Updates to single datapoints are done no faster than the given value (default is 5 seconds). By choosing zero every received data will be stored. Since E380 is sending data very fast (more than 2 values per second), it's recommended not to use zero here. This would put a high load on the ioBroker system. +* If you have connected E3 devices via CAN bus, e.g. Vitocal and VX3, you can collect data exchanged between those devices in realtime by listening. Press "+" to add a line, check "active" chackbox, select a device and edit "Min. update time (s)". It's feasable to use 0s here, however, I recommend to keep to the 5s. +* Finally, you may add schedules for requesting data via UDSonCAN protocol. Again press "+" button and edit the setting. You may have several schedules with different (!) timings. By this you can request some datapoints more often than others. Default value of 0 for "Schedule (s)" means, those datapoints will be requested just once during startup of the instance. +* If you have configured a CAN adapter connected to the **internal CAN bus**, a tab "ASSIGNMENTS TO INTERNAL CAN ADAPTER" is visible. Please configure the devices for colletion there. UDSonCAN is not supported on internal CAN bus by E3 devices. +* That's it.

By just listening you will receive available data in realtime right on changing. So you can get fast changing data (e.g. energy flow values) and slowly changing data (e.g. temperatures) directly on each change.
