# Wallbox
You can connect your Teslalogger to your Wallbox to calculate the efficiency of charging or the percentage of photovoltaics used to charge your car. 
## Supported Wallboxes
- OpenWB
- OpenWB 2
- go-eCharger
- Tesla Wallbox Gen 3
- KEBA KeContact P30 (P20?)
- Shelly 3EM for all unsupported wallboxes or without build in meter: https://amzn.to/3nUEuO0
- Shelly EM for 1 phase charging
- SmartEVSE 3
- EVCC
- WARP

# Settings
Go to admin panel and select the car you want to use for the wallbox. Go to Extras / Wallbox.
Every car has it's own wallbox settings. 

Choose your wallbox and set the host name of your wallbox e.g: http://192.168.1.174 or http://192.168.178.33:7070
Make sure you don't forget http:// or https:// at your host settings. Just the IP address won't work!

## Param
Some types of wallboxes needs some special params to work as expected.

# OpenWB
### Param:
LP1 - LP8 Charging point used for this car. Default: LP1

# OpenWB 2
Please enable "HTTP-API" in OpenWB settings
For host use https and port, example: https://192.168.1.38:8443
Per default and without params TeslaLogger uses first founded Wallbox and Grid meter.
If you have multiple Wallboxes or you have problems with automatic settings:
Param:
- "CP:26": chargepoind id = 26, grid id will be assumed from hierarchy
- "G:7|CP:27": Grid meter with id = 7 and chargepoind id = 27

# go-eCharger
Please make sure you enable HTTP API v1 in "Internet / Enhanced Settings"

# Shelly EM
### Param:
C1 or empty for channel 1

C2 for channel 2

# EVCC
### Param:
Wallbox or Car title from EVCC

# WARP
### Param:
Per default and without params TeslaLogger assumes, that wallbox has internal meter with ID 0, value_id=209 and grid meter with ID 1, value_id=209

If it's not a case, provide paramas in this format:
- "W:2:210": only Wallbox meter with ID 2 and value_id=210
- "G:2|W:0:210": Grid meter with ID 2 and default value_id=209, wallbox meter with ID 0 and value_id=210

For more information about value_ids: https://github.com/Tinkerforge/esp32-firmware/blob/master/software/src/modules/meters/meter_value_id.csv

# Dashboard
In Charging History you can see the efficiency of charging and percentage of photovoltaics if the wallbox supports this value.
