SynapseCore Legacy

1.Introduction #


Collect your building data in just a few minutes

SynapseCore Legacy

SynapseCore Legacy is a LoRaWAN gateway designed to ensure the collection, storage, and reliable transmission of your field data to EwattchCloud.

Robust and high-performance, it can integrate up to 1,000 LoRaWAN sensors while ensuring service continuity thanks to local data storage in the event of a network outage.

Designed for demanding technical environments, it combines multiprotocol connectivity, local control, and native compatibility with EwattchCloud for centralized, secure, and scalable management of your installations.

Features
  • High-capacity LoRaWAN gateway

Natively compatible with EwattchCloud, it can integrate up to 1,000 LoRaWAN sensors and ensure long-range communication (up to 15 km in open field).

  • Secure local data storage

Data storage for more than 48 hours in case of network outage, ensuring data integrity and measurement continuity.

  • Scan to Cloud

Quick provisioning by scanning the QR code on the back of the product using the dedicated application for simplified deployment.

  • Integrated Modbus

Exposes Ewattch sensor variables via a Modbus TCP server (Modbus Table) and enables external variables to be transmitted to EwattchCloud as a Modbus TCP client.

  • Simple scheduling control

Manage up to 16 configurable schedules from EwattchCloud, with autonomous operation when offline.

  • Remote updates & maintenance

Secure software updates via VPN and simplified maintenance access.

2.Installation and commissioning #

Network Infrastructure

Network Configuration

Firewall
  • Allow: MAC or IP addresses of the gateways to communicate outbound through ports 80 (http), 443 (https) and 123 (NTP) to the server www.ewattchcloud.fr, and through port 53 to the configured DNS servers.
  • SynapseCore: allow MAC or IP addresses to communicate outbound through ports 51820 and 51821 (TCP and UDP) to wg.vpn.ewattch.cloud.
  • Whitelist: add www.ewattchcloud.fr and wg.vpn.ewattch.cloud to the firewall whitelist.
  • RAK: if present on the network, allow MAC or IP addresses to communicate with Ewattch gateways through ports 1780 and 1782 (TCP and UDP).
Addressing
  • WAN Port: By default, the WAN port is set to DHCP. Check that the gateways correctly obtain network parameters (gateway, DNS). If switching to a static IP, set the DNS to 8.8.8.8 (Google DNS) if necessary.
  • LAN Port: The SynapseCore LAN port has a fixed IP address of 192.168.25.1/24 and acts as a DHCP server.
DNS
  • DNS Access: gateways must be able to access DNS (Domain Name Service), either via the gateway (DNS relay) or directly (e.g., 8.8.8.8 on port 53).
  • Domain: gateways must be able to access the domain www.ewattchcloud.fr.
Proxy
  • HTTP Proxy: if a proxy is used, it will not be configured automatically. Configuration must be carried out directly in the gateways.
  • Authentication: authenticated proxies are not supported.

Configuration on Ewattch Cloud

The SynapseCore does not require any prior configuration from the client. It is automatically pre-configured by us before shipment. You only need to connect your sensors using the Scan to Cloud feature, an intuitive solution that simplifies provisioning in just a few clicks.
