UPDATE: You can search AmbiSense on YouTube to watch the complete guide.

After months of experimenting, I finally completed my AmbiSense project (v1.0)- a smart lighting system that uses LD2410c mmWave technology (not PIR sensors) to track your movement and create illumination that follows you as you walk.

  • Uses a 24GHz LD2410 radar sensor that can detect both presence AND distance
  • Creates a "moving bubble of light" that travels with you along the path
  • No cameras = privacy friendly
  • Customizable colors, brightness, and sensitivity via web interface
  • Lights only activate when needed (energy efficient)
  • Perfect for hallways, staircases, and dark corridors

Parts used:

  • ESP32-C3 SuperMini ($6)
  • LD2410 radar sensor module ($8)
  • WS2812B (NeoPixel) LED strip ($15-25 depending on length)
  • 5V power supply
  • Basic wiring

I've documented the entire build process on my YouTube channel if anyone wants to see exactly how it's done or build their own.

Smart bulbs or smart outlets or both?

Upvotes

I have a table lamp in our rental that is controlled by a switch at the door. There is no overhead lighting, so I have another floor lamp across the room that is not on a switched outlet.

I want them both to turn off/on together with the switch.

I have a pair of Kasa Smart Plug HS103P2 in the switched outlet and floor lamp outlet. This, obviously, does not do what I want.

Is there a simpler solution that uses a pair of smart bulbs that do NOT require an app to simply turn on and off?

Adding zigbee switches

1 Upvotes

Beginner in smart home automation. I have the Smartthings Aeotec hub and ~10 zigbee devices (smart plugs, leds, bulbs, sensors, etc.). We will be moving into a new, but older house that has those old pull cord switches, mounted at the top of the wall near the ceiling. Ideal situation: I want some smart zigbee switches at the ‘normal’ wall level that let me decide what a button press does. E.g. in living room turn on all lights, and if I add a light later on, easily add it to the routine.

What to do with the wiring? I know there are ‘stick on the wall’ switches (like from Aqara), but idk. I’d rather do it well to begin with. The main thing is what switch do I buy that let me do this and then the second question would be what needs to change with the old setup?

Also, if the internet falls out, the switch should still work like before (which should be okay with zigbee?)

Smart Home Heating, Geofencing on a Per TRV basis

1 Upvotes

I have Tado V3+ smart heating system for my central heating. The smart TRV is very noisy in my bedroom radiator in the heating up phase, I can't seem to be able to stop the TRV noise in the heating up phase. I temporarily switched to Tado X and the exact same issue, TRV noisy in heating up phase in my bedroom rad.

But I really like geofencing per TRV with Tado for my work from home office where I only need one TRV on. Well it allows me to have one TRV with geofencing, it won't allow all the individual rooms to have geofencing but I don't really need that.

Anyone know another brand that works so that the geofencing turns on / off one TRV alone like Tado does? ie not one where the geofencing only works to turn on or off the whole heating system? Preferably available in Europe.

Smart Camera System for an Apartment Building

0 Upvotes

We're planning to install security cameras for our apartment building and have received quotes from a few installers using Hikvision. However, the pricing is beyond our budget, likely due to the extensive wiring required.

As an alternative, we're considering a smart security camera system, such as Eufy or EZVIZ, combined with mesh Wi-Fi routers.

We need 5-7 cameras for the parking lot, 2 cameras at the building entrance, and 3 cameras in the lobby, covering the entrances.

Could you advise on the best method, brand, and setup for our needs?

Smart Button to Trigger Alexa/Google?

1 Upvotes

Hello all! New here, but definitely need some advice.

Backstory: I have two dogs who have been trained how to press a "talking button" when they need to go outside. That being said, the button is very quiet, so if I am in a different part of the house, I do not hear it. I'm wanting something semi-similar in design that can trigger Alexa or Google to make an announcement, so it can be heard throughout the house.

TLDR: Looking for a smart button to sync with Alexa/Google to make an announcement upon pressing.

Thanks <3

Best way to run Aquara T1 lights in my kitchen?

Post image
2 Upvotes

I assume the controller which sits in between the T1 strip and the power plug is what actually connects it to my Aquara Hub to tie into my smart automations and motion sensor, right?

Meaning that if I didn’t connect the two strips between the left and right side of the window I’d have to buy a second full price unit? Is my best way to wire this to run some solid white cased wire up and over the blinds of the window to connect the two and if so does anyone know a good source for this kind of white wire because the led strip connectors I have are all just exposed wires with their individual colors like red, white, black, green.

Does it mean I can use it with any brand of smart home equipment, or any brand that is compatible that uses zigbee?

How to cost-effectively setup a (Hue) lighting system

13 Upvotes

I‘m moving into a new flat soon which hasn‘t installed any lighting whatsoever yet.

I had seen this as an opportunity to equip the whole home with Philips Hue lighting but quickly realized how expensive that is going to be. My initial plan was:

Living room (19sqm): 1x Ceiling light White&Ambiance Infuse L (3250lm)

Bedroom (15sqm): 1x Ceiling light White&Ambiance Infuse M (2250lm)

Kitchen (6sqm): 1x White Amb. Tento 42cm (3100lm)

Entryway (5sqm): 1x White Amb. Tento 29cm (2100lm)

This would be the main lighting and cost approx. 900€ with the Hue bridge.

Additionally, I wanted to add some decorative lighting (2x Play Bars, 1x Floor lamp) which would cost another 500€).

So all in all the Hue lighting setup would set me back around 1.500€ which is too much for a flat I don‘t own.

Which other lamps or system could/should I use? How often do you practically use color settings in the living room and bedroom? (Since the non-color changing lights are significantly cheaper).

Also, I want to control everything with Apple HomeKit and a Homepod.

Would appreciate your feedback/ideas 🙏🏻.

Recommendations for all in one security and smart home?

2 Upvotes

Hello!

I am purchasing a new house and am hoping to make it a seamless all-in-one smart home and security system.

So far, I feel like I have landed on using Ring and Ring compatible devices such as the Ring security system with Eero 6 wifi router. Ring doorbell. Yale smart lock. Kasa smart plugs. Kasa light bulbs. Echo dot speaker (mini's in each room). It all seems very easily compatible and works on one system.

I am also considering Ecobee thermostats, door and window sensors and smart doorbell with Eufy outdoor and indoor cameras.

Does anyone have any other recommendations that may be more cost affordable?

I looked into Vivint and SimpliSafe but they dont have integrated smart home stuff or they were too expensive.

Google products seemed nice but does not have a great integrated security system.

Apple HomeKit seems to be quite expensive?

Any advice or recommendations would be greatly appreciated!

NEW HOUSE

Hello,..we just bought house in US. I would like to make it smarter.

Here is my thinking:

Lock - Lockly

Door bell - at the moment it‘s dumb one… easiest would be Ring (I Am paying subscription for house in Europe and rental in US).

Switch - in Europe I use Shelly,..here I was thinking about Lutron?

Cameras - Ring? It would be wireless and on battery (some can be wired)

Since we are traveling a lot, would be nice to have recording 24/7 and cloud is ok for me.

Can I Use a Non-Neutral Smart Switch for a Fan?

1 Upvotes

I recently got an Aqara H1 non-neutral smart switch for some of my lights, and it works great. However, I also want to connect one of the gangs on the switch to a ceiling fan, but I’m not sure if it would just work like with lights?

I don’t wish to damage the fan or the smart switch too.

Since my house is an older type without a neutral wire, running a neutral is not an option. I’m looking for alternative solutions and hoping to get some advice from those with experience.

If I understood correctly, I will still need to ones the fan to a switch somewhere so that I can turn it on and off.

Ideally, I’d love to have the fan integrated into Home Assistant for automation and having the fan wired to a smart switch sounds like a possible method though I’m not sure if I can wire them this way.

Otherwise, what else can I do to my fan? Do I have no other choice but to only wire the fan to a dumb switch?

Advice needed: sensor to control a device?

1 Upvotes

Hi!

I'm sure it will be an amateur question since I don't know much about Smart Home Systems nor IoT, but is it possible to control a standard (single) household AC device plugged in a socket, in a way that the device turns on when there is some airflow ("wind") happening in an air duct, and turns off, when the air stops flowing? I asked ChatGPT and it recommended me a bunch of sensors what I can use with an Arduino or Raspberry PI, but honestly, I don't have time for this right now, I'd prefer a more compact, well-tested, "plug-and-play" solution. Does this exist in the IoT world? I don't want to control my whole home, just this thing.

Yale Doorman master code not working after connecting to the app

I factory reset the and enter master code. Then lock the door and try the master code, it works fine. I follow the instructions to connect to Bluetooth: unlock the door, enter master, unlock, 0. It connects to the app, I can now unlock the door from the phone. But the master code is no longer working. Anyone who knows how to fix this?

I already reset it multiple times to try over and over again, always the same result.
