The guides cover reading energy flows day to day, configuring the building and the equipment with their KNX links, then energy control: load shedding, solar surplus, tariff periods and EV chargers (IRVE). ## Getting started 1. [Find the menus](https://wiki.can-nx.com/en/guides/emergy-access/): **Dashboard**, **Equipment**, **Building Config**, **Energy Control**, **IRVE** and **Chart'nX**. Check the project name in the top bar: demo mode offers only **Dashboard** and **IRVE**, with simulated data. 2. [Install access on your device](https://wiki.can-nx.com/en/guides/emergy-install/) with **Install app** or, on iPhone and iPad, with **Share** then **Add to Home Screen**. ## Main tasks **Monitor and control day to day** - [Read flows and consumption](https://wiki.can-nx.com/en/guides/emergy-dashboard/): **Solar**, **Battery**, **Grid** and **Building** cards in instantaneous power (W or kW), **Conso** breakdown and **Equip.** cards. - [Choose Auto, OFF or ON](https://wiki.can-nx.com/en/guides/emergy-control/) for a piece of equipment: **Auto** hands control back to automation, **OFF** and **ON** request a forced stop or forced operation. For a setpoint, [send a custom value](https://wiki.can-nx.com/en/guides/emergy-custom/). - [Monitor EV chargers](https://wiki.can-nx.com/en/guides/emergy-irve/) in **IRVE**. - For history and measurement export, [open Chart’nX](https://wiki.can-nx.com/en/guides/chart-open-emergy/). **Configure the building** - [Power network and tariffs](https://wiki.can-nx.com/en/guides/emergy-building-network/): **Basic**, **Off-Peak** or **Tempo** plan, then grid meter measurements over KNX or Modbus, with **1 signed reading** or **2 readings (one per direction)**. - [Solar production and battery](https://wiki.can-nx.com/en/guides/emergy-building-production-storage/): **Bus (KNX / Modbus)** or **Huawei** source, the inverter then being read over Modbus TCP. - [General meter](https://wiki.can-nx.com/en/guides/emergy-building-meter/), [weather location](https://wiki.can-nx.com/en/guides/emergy-building-weather/) and [Presence/Absence and Summer/Winter feedback](https://wiki.can-nx.com/en/guides/emergy-building-signals/). **Configure equipment** - [Create equipment](https://wiki.can-nx.com/en/guides/emergy-equipment-create/), then [fill in its characteristics by type](https://wiki.can-nx.com/en/guides/emergy-equipment-types/): domestic hot water, pool, heating, air conditioning, ventilation, lighting, production or charger. - [Map its KNX measurements and commands](https://wiki.can-nx.com/en/guides/emergy-equipment-knx/), with the group addresses and DPTs validated for the installation. - [Configure an EV charger](https://wiki.can-nx.com/en/guides/emergy-evcp-config/) and its optimization options: **EVlink Pro AC**, **Terra AC**, **LEKTRI.CO**, or **Other** with KNX links. **Control energy** - [Load shedding and solar surplus](https://wiki.can-nx.com/en/guides/emergy-energy-thresholds/): threshold levels in watts and commands sent to each piece of equipment. - [Off-peak, peak and red peak hours](https://wiki.can-nx.com/en/guides/emergy-tariff-control/): equipment concerned, order and, during off-peak hours, switch-on delays. - [Summer/winter and presence/absence variants](https://wiki.can-nx.com/en/guides/emergy-energy-scenarios/) of these settings. ## Troubleshooting [Common questions and troubleshooting](https://wiki.can-nx.com/en/guides/emergy-help/) answers frequent cases: menus hidden by TV mode, sections limited to the demo, **Conso** or **Equip.** missing, **ON** with no effect. To find or delete a configuration, see [the equipment list](https://wiki.can-nx.com/en/guides/emergy-equipment-list/).
