Using External Relays
External relay connectivity is a new feature. Please provide feedback, if you have any findings/issues in your environment.
From version 0.92 Arska supports external relays in addition to GPIO relays connected to the ESP32 board.
To define external relay, set relay type, IP address, and relay id in the channels definition page. Relay configuration does not support password protection, so use relays only in a properly firewall-protected local network.
Shelly Gen 1 supported devices and API. Relay id is a number of connected relay port, starting from 0.
This feature is tested with Shelly 3 EM (relay functionality), version v1.12-3EM-gcf4f7c2
Shelly Gen 2 supported devices and API. Relay id is a number of connected relay port, starting from 0.
This feature is tested with Shelly Pro 2, version: 0.11.0 . (Shelly Gen 2 relays support a minimal set of Gen 1 functionality, so newer Gen 2 devices seem to work also with Gen 1 relay type setting.)
Tasmota is an open-source firmware for ESP devices. Relay id is a number of connected relay port, starting from 1.
Tested with an ESP8266 relay board with Tasmota 12.1.1.
