I use running in a Raspberry Pi as the main hub to automate all my smart home devices. It is set up to connect to my , with a basic interface to start, pause and dock the cleaner. The is more advance, able to map the plan of my home as it scans and cleans the place. Home-Assistant Xiaomi Mi Roborock vacuum cleaner Mi Home app The vacuum cleaner works really well to clean the whole house automatically. But if I want to just clean a particular room at home, I have to use the Mi Home app to draw a rectangle (zone) around the room in the house plan to start the zone cleaning. The app does not save this, so each time I want to clean a different room, I have to repeat the same steps. Wouldn’t it be great if I can automate this? made me realized it may not be difficult to achieve this. This post Hey Google, clean the bedroom The goal is to be able to issue a command to Google Home to tell the vacuum cleaner to clean just a small area at home. Here is step-by-step of what I did: Find out the coordinate of a corner of a room to figure out the scale of the coordinates Map out the coordinates of each room at home Create an recipe with , and to call my Home-Assistance server. IFTTT Google Assistant as the trigger webhook as action Testing app_goto_target command in service dev tool in Home-Assistant Home-Assistant service dev tool can be used to call services for any devices connected to it. There is a command called that can be used to send the vacuum cleaner to any coordinates. app_goto_target The docking point of the vacuum cleaner always have the coordinate [25500, 25500]. This is somewhere in my study room. Through trial-and-error, I figured out the coordinate of a corner of my study room. It can be any point in the house. It will provide a reference to draw a map later with scale later. Screenshot of the Mi Home app that is used to control the Xiaomi vacuum cleaner The Mi Home app has my entire home plan mapped out. I took a screenshot of that, opened it in Sketch and overlaid grids to draw out the x and y-axis. This provides a rough estimate for all the coordinates in the house. Screenshot of my home plan created by the Mi Home app, with grids and coordinates overlaid in Sketch app. The green dot with coordinate [25500,25500] is the vacuum cleaner docking station. The vacuum cleaner supports a command for zone cleaning called . It takes in a array 5-digit-numbers, each describes a rectangle called zone — the first two digits are the coordinates of the bottom left corner of the zone, the second two digits for the top right corner of the zone, and the last digit for number of times to clean a zone. app_zoned_clean With all room coordinates mapped out, I tested them in Home-Assistant and made small tweaks if I have to. The zone can be slightly bigger than the room, but it should not overlap into another room. Testing app_zoned_clean command in service dev tool in Home-Assistant With all the rooms in my house mapped out, the next step was creating IFTTT recipes to allow Google Home to communicate with Home-Assistant to send these commands to my vacuum cleaner. Each recipe was created by choosing Google Assistant as the IFTTT trigger, and webhook as action. Google Assistant as IFTTT Trigger, and Webhook as Action to call API in Home-Assistant It is also possible to create a recipe to get the vacuum cleaner to clean the area a few times because the 5th digit sets the number of times to clean the area. Hey Google, clean the kitchen 3 times Google Assistant as IFTTT Trigger, with option to say a phrase with a number The field takes in an , so it is possible to create an automation that cleans an area with a customized shape. For example, when the vacuum cleaner is mopping the floor in my living room, I would like to exclude the area where the rug is. params array of zones Hey Google, mop my living room Screenshot of the Mi Home app showing the 4 zones in my living room, excluding the area where the rug is That’s it. Now I can ask Google Home to clean any rooms at home.
