Perhaps you want to turn on the light automatically when you enter a room? Or get a notification when someone walks up on your driveway? At Acconeer we use it in our office to detect and display if a meeting room is occupied or empty. Follow the steps below to make your own implementation.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=&#8221;in_container&#8221; full_screen_row_position=&#8221;middle&#8221; column_margin=&#8221;default&#8221; column_direction=&#8221;default&#8221; column_direction_tablet=&#8221;default&#8221; column_direction_phone=&#8221;default&#8221; scene_position=&#8221;center&#8221; text_color=&#8221;dark&#8221; text_align=&#8221;left&#8221; row_border_radius=&#8221;none&#8221; row_border_radius_applies=&#8221;bg&#8221; overflow=&#8221;visible&#8221; overlay_strength=&#8221;0.3&#8243; gradient_direction=&#8221;left_to_right&#8221; shape_divider_position=&#8221;bottom&#8221; bg_image_animation=&#8221;none&#8221;][vc_column column_padding=&#8221;no-extra-padding&#8221; column_padding_tablet=&#8221;inherit&#8221; column_padding_phone=&#8221;inherit&#8221; column_padding_position=&#8221;all&#8221; column_element_spacing=&#8221;default&#8221; background_color_opacity=&#8221;1&#8243; background_hover_color_opacity=&#8221;1&#8243; column_shadow=&#8221;none&#8221; column_border_radius=&#8221;none&#8221; column_link_target=&#8221;_self&#8221; column_position=&#8221;default&#8221; gradient_direction=&#8221;left_to_right&#8221; overlay_strength=&#8221;0.3&#8243; width=&#8221;1\/1&#8243; tablet_width_inherit=&#8221;default&#8221; tablet_text_alignment=&#8221;default&#8221; phone_text_alignment=&#8221;default&#8221; animation_type=&#8221;default&#8221; bg_image_animation=&#8221;none&#8221; border_type=&#8221;simple&#8221; column_border_width=&#8221;none&#8221; column_border_style=&#8221;solid&#8221;][vc_video link=&#8221;https:\/\/www.youtube.com\/watch?v=Jh9ZiQ0msT0&#8243;][vc_column_text]\n<h2>HARDWARE SETUP<\/h2>\n<p>To implement this proof of concept, we used the following hardware:<\/p>\n<ul>\n<li>XM122 + XA122 + regular coin-cell battery. Find out more and how to buy them on the <a href=\"https:\/\/www.acconeer.com\/products\/\">product page<\/a>.<\/li>\n<li>Raspberry Pi version 3 or later with BLE support<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>SOFTWARE<\/h2>\n<p>The software for this application is included in the XM122 SDK, and it is easy to get it up and running with a few simple steps.<\/p>\n<h3>XM122<\/h3>\n<ul>\n<li>Download the XM122 SDK from <a href=\"https:\/\/developer.acconeer.com\/\">https:\/\/developer.acconeer.com\/<\/a><\/li>\n<li>Install the application called ble_monitor_presence on your XM122<\/li>\n<\/ul>\n<h3>HOME ASSISTANT<\/h3>\n<ul>\n<li>Install Home Assistant on the Raspberry Pi as described <a href=\"https:\/\/www.home-assistant.io\/installation\/\">here<\/a><\/li>\n<li>In Home Assistant install the Passive BLE monitor integration as described <a href=\"https:\/\/custom-components.github.io\/ble_monitor\/Installation\">here<\/a><\/li>\n<\/ul>\n<p>Now the XM122 should be discovered as a motion sensor by Home Assistant.<\/p>\n<p>&nbsp;<\/p>\n<h2>IMPLEMENTATION TIPS<\/h2>\n<p>Depending on the distance you want to detect people or moving objects you will need to change the settings in the ble_monitor_presence. What the settings should be depends a lot on the specific environment and use case, it is recommended to try this out using exploration tool. Once you know your settings you should update the c code for the app.<\/p>\n<p>&nbsp;<\/p>\n<p>Keep in mind that the battery life will vary depending on your measurement frequency, since more frequent measurements of course consume more power. In our example we use a 0,2m \u2013 3,2m default range and measure two times per second.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<h2>TRY IT ON YOUR OWN AND GET IN TOUCH<\/h2>\n<p>To build your own version of the smart home presence setup, make sure you have all the <a href=\"https:\/\/www.acconeer.com\/products\/\">hardware<\/a> you need according to above. Combined with a PC running our Exploration Tool you can play around with this and many other use cases. To get started, head over to our <a href=\"https:\/\/developer.acconeer.com\/\">Developer site<\/a> where you find software downloads, getting started guides and more.<\/p>\n<p>&nbsp;<\/p>\n<p>If you try this, or work on something else, we\u2019d love to hear about your project!
