⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact customer support for warranty service if, after following all self-resolution and verification steps, the device exhibits persistent failures not caused by misuse, incorrect installation, or electrical/Wi-Fi network issues. This includes manufacturing defects such as permanent failure of one or more relays without overload, the module not powering on even with correct input, or the Wi-Fi module failing to connect to the network after multiple attempts and infrastructure checks. Refer to the seller's warranty and marketplace return policy for details.
