This detailed guide explains every step of checking, connecting and pairing for optimal operation with Zigbee2MQTT and Home Assistant. Follow these precise instructions to replace a faulty switch without difficulty.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Je_verifie_bien_le_modele_recu\"><\/span>I check the received model<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>Many references of Zigbee modules exist on the market, each with different specificities. The model I received clearly bears the reference KR2303 engraved on the case. This identification is crucial to ensure compatibility with available firmwares and tutorials.<\/p>\r\n<p>This model KR2303 is distinguished by the lack of an integrated energy monitor. Unlike other more advanced versions, it focuses only on on\/off switching, making it ideal for simple applications such as controlling lighting or basic electrical appliances without the need for consumption tracking.<!--more--><\/p>\r\n<p><a href=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-rotated.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6059\" src=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-rotated.jpg\" alt=\"View of the case KR2303 with visible reference\" width=\"279\" height=\"372\" srcset=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-rotated.jpg 1500w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-rotated-600x800.jpg 600w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-225x300.jpg 225w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-768x1024.jpg 768w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101542-1152x1536.jpg 1152w\" sizes=\"auto, (max-width: 279px) 100vw, 279px\" \/><\/a> <a href=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-rotated.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6060\" src=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-rotated.jpg\" alt=\"KR2303 module connector detail\" width=\"279\" height=\"372\" srcset=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-rotated.jpg 1500w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-rotated-600x800.jpg 600w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-225x300.jpg 225w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-768x1024.jpg 768w, https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/20240120_101546-1152x1536.jpg 1152w\" sizes=\"auto, (max-width: 279px) 100vw, 279px\" \/><\/a><!--more--><\/p>\r\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-6407\" src=\"https:\/\/www.sigalou-domotique.fr\/wp-content\/uploads\/2024\/01\/taille.png\" alt=\"Compact dimensions of the KR2303 module for table installation\" width=\"281\" height=\"143\" \/><\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Jai_trouve_lexplication_des_connecteurs_S1_et_S2\"><\/span>I found the explanation of connectors S1 and S2<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>The S1 and S2 connectors correspond to the inputs for external switches in 2-way mode (two-way).
