TeltoCharge can communicate with a dedicated smart energy meter and adjust its power consumption based on the meter's readings. This functionality helps protect the home's electrical grid from overload during peak hours and optimizes energy usage to match the user's habits. The smart energy meter should always be installed in the main electrical cabinet, as shown below.

== SMART METER AND TELTOCHARGE COMMUNICATION ==
== MODBUS RTU METERS ==
Smart meter and TeltoCharge communicates via Modbus RS-485 protocol. In order to achieve smooth communication, it is recommended to use communication cable according to this protocol. Check example below.
To access energy measurement through Modbus RTU, connect both the charger and the meter together using RS485 terminal for meter.
 
[[File:DLB meter.png|frameless|808x808px]]
 
=== RS485 communication ===
For RS485 communication it is recommended to use a twister pair communication cable. Check example below.

== LOAD BALANCING CONFIGURATION ==
To ensure everything works correctly, please apply the following setup :
# Open user menu
# Open "'''''Installer Menu'''''"
# Open "'''''Dynamic Load Balancing'''''" menu
# Enable "'''''Load Balancing'''''"
# If smart meter is connected with RS485 wires, press "'''''Search For Device'''''"

== MODBUS TCP/IP METERS ==
To access energy measurement through Modbus TCP/IP, connect both the meter and your charger to your network. Charger has two options: either Wi-Fi or Ethernet cable.
=== Connecting Shelly 3PRO ===
Download the '''Shelly smart control''' app and setup the device to connect to your network. After it is configured, find the IP address given to the meter.
[[File:Shelly wiki.png|frameless|935x935px]]
'''''Note:''' Copy the IP as it will be used in EV charging app to connect the meter to the station''
=== Connecting HomeWizard P1 ===
Follow this full guide for easy installation: [[Media:HomeWizard P1 guide.pdf|HomeWizard P1.pdf]]
Or in short - install the HomeWizard meter to the P1 port of your utility meter.
[[File:Wizard p1 utility meter.png|frameless|284x284px]]
Download the '''HomeWizard''' app and follow the setup for the meter to connect to your network. After it is configured, find the IP address given to the meter.
[[File:Homewizard wiki 1.png|frameless]] [[File:Homewizard wiki 3.png|frameless|592x592px]]
'''''Note:''' Copy the IP as it will be used in EV charging app to connect the meter to the station''
=== Load balancing using Network meter ===
The example below is for Shelly 3Pro smart meter integration, but is identical when using HomeWizard P1.
To connect the meter to the station, go to '''load balancing''' section in the app, choose '''network meter''' and the model you're using.
[[File:Shelly DLB 1.png|frameless|938x938px]]
After that select the '''IP address''' as was shown in the Shelly app. Set '''max grid load''' to match the value allowed by the grid. If everything is done right - the status should indicate that the network meter has successfully connected.

As it is possible to change the EVSE settings by using the TeltoCharge mobile application, it is recommended for the primary device to read, compare, and change settings as needed based on user preferences and real-time requirements, ensuring a seamless and secure charging experience for electric vehicle owners. Continuous monitoring and adjustment of EVSE settings enable the primary device to stay synchronized with user inputs, maintain optimal charging conditions, and promptly respond to any changes initiated through the TeltoCharge mobile application, thereby enhancing overall efficiency and user satisfaction.
