Great news from eWeLink Team! As many Home Assistant users have eagerly anticipated, the eWeLink-Remote Add-on has finally arrived! It supports devices such as R5, R5W, S-Mate, and S-Mate2, serving as eWeLink-Remote gateways.
To use this add-on, you’ll need to boot and run Home Assistant on iHost with a pre-flashed microSD card. However, it works seamlessly on most Home Assistant instances. Additionally, make sure Home Assistant’s Bluetooth functionality is available - BT hardware is required for this.
Note from developers: 64-bit x86 architecture isn’t currently supported. We plan to work on it next week. So don’t despair, mini PC users

It provides full control over the Sonoff R5 BLE MQTT remote using MQTT Discovery-based device triggers. It supports all six buttons with three click types: Single, Double, and Long Click. To use it, your Sonoff R5 must be discovered via MQTT and expose device triggers.
Happy computing
