It sits on your home network and talks by radio to your iNELS Wireless units. That lets you control them from the **iNELS app** and voice assistants, see their state, and run **scenes, time schedules and heating programs**. Units you have already paired by hand keep working on their own. The gateway adds the app and the automation on top. See [Transmitters, receivers and gateways](/inels-home/inels-wireless/transmitters-receivers-and-gateways.md). ![eLAN-RF-103](https://2503278529-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FkoLW6hWCvDgagoswDVfD%2Fuploads%2FryLUcN18hqITj1tTbtrm%2Felan-rf-103.png?alt=media) ## At a glance | | | | ------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | Role | Gateway between iNELS RF units and the iNELS app, voice assistants (Google Home, Amazon Alexa) and other third-party devices | | Units it can handle | Up to 70 | | Versions | **eLAN-RF-103** (network cable) · **eLAN-RF-Wi-103** (network cable and Wi-Fi) | | Radio | RFIO2, two-way, 866–922 MHz, up to 100 m in open space | | Network | Ethernet RJ45, 100 Mbit/s. The IP address comes from your router (DHCP) by default | | Power | Adapter 110–230 V AC / 5 V DC, 2 A, USB-C connector (included) | | Set-up | iNELS app and the built-in web interface | | Antenna | Internal AN-I included. External AN-E can be fitted on the SMA connector | | EAN | 8595188180443 | ## What it does * Sends and receives commands for up to **70 units** and runs the programs you set for automatic control. You can start with one unit and add more later. * Because the radio link is **two-way**, it shows the current state of each unit. * The iNELS app can: regulate hot water or electric underfloor heating · measure temperature with wireless sensors · switch appliances (garage doors, blinds, fan, irrigation, sockets) · dim lights · switch by time (for example delayed light-off when you leave a room) · remote control · scenes (one press runs several commands). * Works with the voice assistants Google Home and Amazon Alexa. ### Limits | What | Maximum | | ------------------------------------- | ----------------------------------------------- | | Units (actuators) | 70 | | Rooms | 60, with up to 32 units in one room | | Scenes | 30, with up to 30 actions in one scene | | Temperature zones | 16 | | Heating and cooling units in one zone | 10 for heating and 10 for cooling (20 in total) | | Time schedules (timetables) | 20, with up to 20 assigned units in the plan | | Intervals in one time schedule | 8 | | Central heat / cold sources | 5 | ## eLAN-103 or eLAN-204? Both are gateways for iNELS Wireless. The main differences are listed below. For the [eLAN-204](/inels-home/inels-wireless/devices/system-units/elan-204.md) see its own pages. | | eLAN-103 | eLAN-204 | | ---------------------------- | ----------------------------------------------------------------------------- | ------------------------------------------------------------------------------------- | | Connection to your network | Network cable (Wi-Fi only on the eLAN-RF-Wi-103 version) | Built-in Wi-Fi 2.4 GHz (access point and client) | | Radio protocols | RFIO2, 866–922 MHz | RFIO, RFIO2, RFIO3, 868 MHz | | Radio range, open space | up to 100 m | up to 200 m | | iNELS Wireless units | up to 70 | up to 70 | | iNELS Home devices | — | up to 20 | | MQTT for third-party systems | — | yes | | Push notifications | — | yes | | Web interface | Settings, configuration backup, firmware update (units are set up in the app) | Tabs for Devices, Rooms, Scenes, Heating/Cooling, Time Schedule, Automations, Service | | Antenna | Internal AN-I, external AN-E optional | Integrated | | Shape and weight | Box 90 × 52 × 65 mm, 136 g | Round, Ø 95 × 25 mm, 92 g; also wall or ceiling mounting | {% hint style="info" %} The **RFRP-20N repeater** can extend the radio range of both gateways — see [RFRP-20N repeater](/inels-home/inels-wireless/devices/system-units/rfrp-20n-repeater.md). {% endhint %} ## First start {% stepper %} {% step %} ### Connect power and network Connect the eLAN-RF-103 to the power adapter and, with an Ethernet cable, to your router. The router gives the eLAN an IP address. By default the eLAN is set to get its address automatically (DHCP). {% endstep %} {% step %} ### Find it In the iNELS app open the account / gateway administration menu and press **+**. The app searches your network and lists the eLAN-RF-103 it finds, with its IP address. Your phone must be on the same home network. You can also use the **ELKO Finder** program (on the product page). {% endstep %} {% step %} ### Open the web interface Type the IP address in the address bar of a web browser. The login page opens. Factory login: name **admin**, password **elkoep**. {% endstep %} {% step %} ### Set it up You can log in as **Administrator** (all rights), **Owner** (limited rights for setting and control) or **User** (control only). Cloud connection is set up with the app. {% endstep %} {% endstepper %} {% hint style="warning" %} Change the factory login after the first start. The same default password is published in the manual. {% endhint %} ## Adding your units How to put receivers and transmitters on the gateway is on one page for all gateways: [Adding paired devices to a gateway](/inels-home/inels-wireless/devices/system-units/adding-paired-devices-to-a-gateway.md). The eLAN-103 is configured in the iNELS app. ## Web interface | Part | What it is for | | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------- | | eLAN RF (top bar) | Shows firmware, hardware, API, web and MAC information | | Overview, Logging | For service. Logging saves a record of events that you can download or delete | | Settings → Device | Change the name of the device and choose the radio frequency | | Settings → Account | Change login name and password | | Settings → Network | DHCP or static IP address; date and time (read from an SNTP server by default; manual setting possible); time zone; automatic summer / winter time | | Settings → Cloud | Switch the cloud connection on or off and see its status. The cloud is set up with the app | | Configuration backup | Create a backup in the eLAN memory, download it to your computer, restore it from memory or from a file | | FW update | Load new firmware: pick the downloaded file (it must end in .efw) and press Update | After a firmware update the eLAN restarts and keeps your settings (IP address, login data, visualisation panel). **Do not switch it off or press Reset during the update.** ## Reset button | Hold the button on the front panel | What happens | | ---------------------------------- | ---------------------------------------------------------------------------------------------------------------------- | | Short press | The eLAN restarts | | More than 5 s | Network settings are reset | | About 10 s | Complete reset to factory settings. IP address and login are reset, and the eLAN goes back to automatic address (DHCP) | ## LED reference | LED | Meaning | | ----------------- | ------------------------- | | STATUS — green | Normal mode | | STATUS — orange | Start-up / initialisation | | STATUS — red | Error | | RF (green) | Radio communication | | Ethernet — green | Operating status | | Ethernet — yellow | Communication | ## Placing it * Keep at least **1 cm** between the gateway and the units it controls. * If the eLAN sits in a **metal switchboard**, use the external AN-E antenna for a better signal (tightening torque of the antenna connector: max. 0.56 Nm). * If the signal between the eLAN and a unit is weak, use the **RFRP-20 / RFRP-20N** repeater. ## Troubleshooting | Symptom | What to do | | ----------------------------------- | --------------------------------------------------------------------------------------------------------------- | | The app does not find the eLAN | The phone must be on the same home network as the eLAN. Try the ELKO Finder program | | You do not know the IP address | The app lists it when you search (+ in the gateway menu), or use ELKO Finder | | Login or address is wrong or lost | Hold Reset for about 10 s — IP address and login return to factory settings | | A unit is not reached from the eLAN | Check the distance (open space up to 100 m), use the external antenna in a metal switchboard, or add a repeater | ## Technical parameters | | | | ------------------------------- | --------------------------------------------------------------- | | Radio | RFIO2, two-way addressed message, 866–922 MHz | | Range | Open space up to 100 m | | Antenna | AN-I 1 dB (internal), SMA connector for AN-E | | Network | Ethernet 100 Mbit/s (RJ45); Wi-Fi on the eLAN-RF-Wi-103 version | | Supply | 5 V DC / 0.5 A; adapter 110–230 V AC / 5 V DC, 2 A (USB-C) | | Operating / storage temperature | −20 to +50 °C / −25 to +70 °C | | Protection / pollution degree | IP20 / 2 | | Working position | Any | | Dimensions / weight | 90 × 52 × 65 mm / 136 g | ## Downloads * [Instruction manual eLAN-RF-103 (PDF, EN)](https://www.elkoep.com/media/import/Elko/eLAN/eLAN-RF-103/EN/Manual_eLAN-RF-103.pdf) * [Datasheet eLAN-RF-103 / eLAN-RF-Wi-103 (PDF)](https://www.elkoep.com/media/import/Elko/eLAN/eLAN-RF-103/EN/Datasheet_eLAN-RF-103_eLAN-RF-Wi-103.pdf) * [Product page](https://www.elkoep.com/smart-rf-gateway---elan-rf-103) — firmware and the ELKO Finder program are on this page
