Identifying that the server would benefit from being low power, Milos opts for a&nbsp; Raspberry Pi 3B+ (though any Raspberry with a wireless LAN connection will work), while the nodes will be a Raspberry Pi Pico W and an Arduino MKR 1000 (both could be done with a Pi Pico W, but Milos notes that the Arduino has already been a part of the project for the past five years!). Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;. Using the Raspberry Pi 3B+ it will work as the message coordinator, so all communication goes through it. Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls. You can find more information on setting up Node Red and Mosquitto for this project below, be sure to check the official documentation with the latest downloads.</span><span>&nbsp;</span></p> <p><span data-contrast="auto">After setting up the broker Milos quickly has a way to receive commands on his nodes and a way of sending the sensor data to the server.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-03-81/PXL_5F00_20240328_5F00_071346012.MV_7E00_2.jpg" /></span></p> <h2 id="mcetoc_1hssqmj0j1"><span data-contrast="auto">The Arduino Node</span><span>&nbsp;</span></h2> <p><span data-contrast="auto">Again, please be aware that this project can involve working with high voltages.

Identifying that the server would benefit from being low power, Milos opts for a&nbsp; Raspberry Pi 3B+ (though any Raspberry with a wireless LAN connection will work), while the nodes will be a Raspberry Pi Pico W and an Arduino MKR 1000 (both could be done with a Pi Pico W, but Milos notes that the Arduino has already been a part of the project for the past five years!). Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;. Using the Raspberry Pi 3B+ it will work as the message coordinator, so all communication goes through it. Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls. You can find more information on setting up Node Red and Mosquitto for this project below, be sure to check the official documentation with the latest downloads.</span><span>&nbsp;</span></p> <p><span data-contrast="auto">After setting up the broker Milos quickly has a way to receive commands on his nodes and a way of sending the sensor data to the server.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/PXL_5F00_20240328_5F00_071346012.MV_7E00_2.jpg" /></span></p> <h2 id="mcetoc_1hssqmj0j1"><span data-contrast="auto">The Arduino Node</span><span>&nbsp;</span></h2> <p><span data-contrast="auto">Again, please be aware that this project can involve working with high voltages.

Identifying that the server would benefit from being low power, Milos opts for a&nbsp; Raspberry Pi 3B+ (though any Raspberry with a wireless LAN connection will work), while the nodes will be a Raspberry Pi Pico W and an Arduino MKR 1000 (both could be done with a Pi Pico W, but Milos notes that the Arduino has already been a part of the project for the past five years!). Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;. Using the Raspberry Pi 3B+ it will work as the message coordinator, so all communication goes through it. Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls.

Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;.

Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls.

In their &lsquo;smart room concept&rsquo; we can see what he wants to control and how he intends to interact and control them. With separate nodes for each component, controlling window access, lighting along with sensors and the base server with communications.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing1-_2D00_-Room-Control-Concept.PNG" /></span><span>&nbsp;</span></p> <p><span data-contrast="auto">Milos has three main components to this project; these are a server and two nodes. Identifying that the server would benefit from being low power, Milos opts for a&nbsp; Raspberry Pi 3B+ (though any Raspberry with a wireless LAN connection will work), while the nodes will be a Raspberry Pi Pico W and an Arduino MKR 1000 (both could be done with a Pi Pico W, but Milos notes that the Arduino has already been a part of the project for the past five years!). Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;. Using the Raspberry Pi 3B+ it will work as the message coordinator, so all communication goes through it. Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls. You can find more information on setting up Node Red and Mosquitto for this project below, be sure to check the official documentation with the latest downloads.</span><span>&nbsp;</span></p> <p><span data-contrast="auto">After setting up the broker Milos quickly has a way to receive commands on his nodes and a way of sending the sensor data to the server.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/PXL_5F00_20240328_5F00_071346012.MV_7E00_2.jpg" /></span></p> <h2 id="mcetoc_1hssqmj0j1"><span data-contrast="auto">The Arduino Node</span><span>&nbsp;</span></h2> <p><span data-contrast="auto">Again, please be aware that this project can involve working with high voltages.

Identifying that the server would benefit from being low power, Milos opts for a&nbsp; Raspberry Pi 3B+ (though any Raspberry with a wireless LAN connection will work), while the nodes will be a Raspberry Pi Pico W and an Arduino MKR 1000 (both could be done with a Pi Pico W, but Milos notes that the Arduino has already been a part of the project for the past five years!). Going for a standard protocol for the components to talk together, Milos uses MQTT, with the server running Node Red.</span><span>&nbsp;</span></p> <p><span>&nbsp;<img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/Drawing2-_2D00_-How-MQTT-Works.PNG" /></span></p> <p><span data-contrast="auto">With Milos&rsquo; decision to use MQTT it requires a broker which will be set up on the &lsquo;server&rsquo;. Using the Raspberry Pi 3B+ it will work as the message coordinator, so all communication goes through it. Any connected nodes can either subscribe or publish data to the &lsquo;topics&rsquo; (which are like messaging channels) that the MQTT broker controls.
