Since my air fryer notification I’ve bought 2 more Esp32 Dev boards from The Greal Mall of China- AliExpress. A couple days later I’d read about MMwave sensors and purchased a couple of those too....
The ld1115h. Best thing is it’s much better than the aqaras and cost about 2/3 the price. It was free shipping over £8 so that’s around what it cost to make.
For anyone else wondering how I’m keeping track of who’s where, espresense.com
I tried Room Assistant a year or 2 ago and it SUCKED. I have a 4 storey townhouse and had 2 nodes running Room Assistant and I could be stood next to 1, two floors away from the other and that’s the one it said I was closest to.
The idea is that by detecting the strength of the Bluetooth signal, the node with the best signal was closest, but it just didn’t work (for me).
Anyway espresence is better, especially because I’ve doubled up and I bought 4 esp32 boards with pins off AliExpress for under £12, and arrived within a week.
You connect the little chip to your pc and flash a firmware from Google Chrome, then hook it into your WiFi, go to its page and give it a name, and hook it into your MQTT.
4 boards later I have a node per floor.
Next I added our phones to it by pairing them to it, then deleting the pairing on the phone. Add the Bluetooth connection to HA config and you’re away! Well…
So you have to connect what the boards say to what it means in HA yourself. You get “bedroom” off Espresence and have a Bedroom zone but you have to put the pieces together yourself.
I ended up making binary sensors for each room in Node Red. Did I leave the room? Who else is there, nobody? Ok mark it clear… You could just make helper switches and use them but I was feeling fancy. I’ve already posted recently about the Binary sensor.
But once you’ve done that, you just base your automations off the state of the switches you made.
So the age old “The front room motion sensor stopped detecting, should the lights go off?” question, now becomes…
Huh I must have stopped typing there…
…much easier to solve. I can still have the old “TV on?, wife’s laptop connected to Bluetooth?” bits in, but having Bluetooth presence detection AS WELL makes it much more reliable, for a measly £12
You pair the device to a base station once to create an entity but you don’t have to if you know the mac of your phone. So there’s no pairing involved in the tracking.
You can use the HA app to create a beacon on your phone when you’re on your home WiFi and not pair anything, just plumb the id into HA.
The speed is quite fast but there is still a lot of false positives. I’ve sat and watched mine and my wife’s phones just pinging around the house, but if you add some “for X seconds” to your automations it becomes much more stable.
I’ve got 3 android phones and an iPhone tracked at present
The secret is not caring it’s 4m away as long as it says you’re closest to that one. It’s not accurate, it’s a guess made with software.
As I’ve said I’ve sat at my PC on the front room and watched it say I’m in my bedroom and kitchen.
So for example my front room lights are based around an input boolean. They’re triggered on by motion but back off by whether the TV is on, my wife’s laptop is connected to the WiFi, the pc is switched off, and everyone’s presence is not in the front room. I already did all that and now I have presence as well.
It used to be that my wife would be sat there on her phone and the lights would go out, now because her phone is on her person they stay on.
Like I say, they’re not perfect but they are better than not having them.
I don’t think I’ll ever have my music follow me around the house.
Oh also try instead of basing automations around whether you are in a room, instead use “is not”
So for example when I get out of bed and get up for work by bedroom lights come on with my alarm. When I go downstairs and make a brew I am no longer in the bedroom so my automations turn off the lights in there. Is not “bedroom”
It’s triggered by the motion sensor outside my bedroom door, then it waits for my presence to be anything other than bedroom. Since I’m moving around the house it’ll trigger at some point.
Similarly my sleep automation turns off when the bedroom is no longer occupied. But that’s when my wife gets up 2 hours after me. It’s also triggered by motion, but then waits until my bedroom presence sensor no longer reads anything
Yeah I have a million Bluetooth devices picked up but I’ve only put 4 of them so far into my Ha sensors. Fuck knows what the others are, but we have soany devices in the house that I can’t keep track, then there’s the neighbours’ stuff too…
Interestingly I stumbled across a YouTube short yesterday about hacking an android device from only knowing it’s Bluetooth Mac address, so theoretically I could really piss off my neighbours if they drove me to it.
Just coming back in to say that yeah, now I’ve used it as a primary trigger instead of a secondary check it seems I’m all over the place in Bluetooth land…
I don’t have a motion sensor in my bedroom. I do have an old phone on a charging stand that I use as a Smart Clock, and the camera of that can be used as a motion sensor. It’s pointed at my head when I’m in bed so it’s not in an optimal motion sensor position… Just setting the scene for you.
Now I had an automation that turns bedroom lights on based on motion so when I wake up in the middle of the night for a pee I have a lamp that turns on for five minutes.
Well of course I wanted MORE from this extra from my clock, so I’ve added presence in the room as a primary trigger of my lamps.
I’m stood in my room watching my lights popping on and off again every 30 seconds…
Not great as a primary trigger, more a secondary check.
Anyway I’m gonna try and change it by adding “in room FOR 30 seconds” to my sensors, seems to be helping so far.
Also limiting reporting distance in the settings for each node to 4-6 meters.
Or maybe stop trying to use it as a primary sensor lol
how do you know when to send the notification btw? Did you configure some automation or script that just says how long until notify?
When power drops below a certain wattage I figure the cooking it complete. I’ve set it to 20 because it seems my air fryer drops to 24W every few minutes (when it’s reached temp I guess) and my rice cooker drops below 50W when it’s on the Keep Warm cycle.
So above 50W it checks the room and below 20W it calls a notification from the people that were in the room.
Also, as a minor annoyance, I could only flash the board from chrome when connected to a WINDOWS machine which I find pretty nasty 🤢, but I may be in the minority there.
Yeah I was a Linux-boy for a decade before a friend gave me a gaming PC he made out of spare parts for me. His one stipulation was NO LINUX so I’m stuck with Windows. But I get ya.
Don’t know why you’ve been down voted but don’t worry I put you back up to positive.
Your toaster automation sounds like what I had to do with the old dishwasher. It would finish the cycle but not stop, so it would continually try to keep up to temperature for some reason.
So I had my notify automation for when it was done and then I had it switch off when the power dropped.
Minor inconvenience to that setup was having to turn it back on again when I wanted to use it. I didn’t wanna have to go under the sink and wade through all the shit in there to get to the plug so I used Google “Hey Google, wash up”
But we have a new one now so I can leave it on.
I also have the washing machine notification. At present it announces when the motion sensor in the kitchen picks up movement and the washer is finished, and sends a notification to the phones in the house when the announcement is made with “I emptied it” and “Ignore” so you walk in the kitchen, get shouted at to empty the washer and a phone notification.
But I am planning on having the same presence detection pick up who triggered the motion sensor and only notify that phone, just haven’t gotten around to it just yet
Just hooked my HA into Google Assistant so it can see my devices with this www.home-assistant.io/…/google_assistant/ then made a Google automation to match the words to turning the plug on.
I'm still having fun with esphome
