This guide provides detailed steps for installing and configuring an MID Meter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is an MID Meter?<\/h3>\n\n\n\n<p>An MID (Measuring Instruments Directive) Meter is a certified power meter that records the energy consumption of your Wallbox charger installation with high accuracy. Complying with the MID standard, it provides precise energy readings, ensuring that you can use this data for billing or reimbursement purposes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. Before Starting: MID Meter and Installation Requirements<\/h2>\n\n\n\n<p>Wallbox supports two types of MID-certified power meters, which can be purchased from our online shop:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Three-phase MID power meter<\/strong>: Suitable for three-phase installations (up to 65A).<\/li><li><strong>Single-phase MID power meter<\/strong>: Suitable for single-phase installations (up to 100A).<\/li><\/ul>\n\n\n\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">We recommend using an&nbsp;<strong>STP Cat 5E cable to perform the installation<\/strong>. <\/span><\/p>\n\n\n\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">Before you begin,&nbsp;<\/span><strong><a href=\"https:\/\/support.wallbox.com\/en\/knowledge-base\/how-to-download-the-mywallbox-mobile-app\/\" target=\"_blank\" rel=\"noreferrer noopener\">download the Wallbox App<\/a><\/strong>, <strong><a href=\"https:\/\/support.wallbox.com\/en\/knowledge-base\/how-to-create-a-mywallbox-account-and-log-in-from-the-app\/\" target=\"_blank\" rel=\"noreferrer noopener\">create an account<\/a><\/strong> and <strong><a href=\"https:\/\/support.wallbox.com\/en\/knowledge-base\/how-to-add-your-charger-to-your-account-by-scanning-its-qr-code-with-the-mywallbox-app\/\" target=\"_blank\" rel=\"noreferrer noopener\">add your charger<\/a><\/strong> to complete the configuration.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2.
