Automotive door lock actuator in the tank, pulling on the flush lever.
I’ve finalized this topic…
As I said - batteries are removed, power supply via wall charger.
I added button for manual activation or check if all is working.
The on-board blue LED I used as pre-warning blinking (~3 sec. before spray),
to avoid spray in someone eyes, etc.
Here is the code - if someone has some suggestions - please provide proposal for changes/improvement…

Hi there
Could you detail the circuit? I’m interested on achieving the same as you did!
Best regards
HP
The circuit diagram is in 1st post…
There are only 4 electronic components.
R1 is 0,33kOhm.
What other detailed info you want?
My version of the implementation of an air freshener with the determination of the presence of a balloon and the determination of the aroma of the balloon. Watch the video.
Smart air freshener with detection of the presence of the balloon and the aroma of the balloon
The project used an automatic air freshener from the company Glade with replaceable cylinders at 2400 spray, which I redesigned and integrated into the Home Assistant.
What opportunities does the redesigned air freshener provide?
- Spray the balloon with Home Assistant automation tools
- Spray the balloon with a built-in timer
- Sensor pressing the physical button on the air fresheners
- Determines the presence of a balloon
- Determines the aroma of the balloon
- It is possible to keep a record of the consumption of each cylinder or only a single one
- Write your own code for sensor output and air freshener control in ESP Home
- Battery powered
- Mains power
Necessary details
Filling on ESP Wemos mini firmware to control the air freshener
In ESP Home, we create a project to control the air freshener

Assembling
We extract the native board and do as in the diagram
Increased native board size for understanding.
- The yellow wire is soldered to the second leg on the right to the chip. This wire is soldered to the esp board, to the contacts D8 GPIO15
- Solder the resistor to 1K, and a green wire to it. Next, solder the wire from the resistor to the esp board, to the contacts D7 GPIO13
- The orange wire is +3.3V and soldered to the esp board, to the contacts +3.3V
- The blue wire is soldered to the esp board, to the GND contacts
- We cut the contact on the track of the textolite coming from the yellow wire. This is necessary so that we can control the dispenser when the timer is off
- We cut the spring with the + contact for the battery compartment and solder the diode (highlighted with a red marker). Why is this necessary? This is necessary to protect the esp board from failure for the reason that if there are batteries in the air freshener and we still connect it to the network, then the chip responsible for voltage conversion will not try to charge the battery and will not get very hot, which can fail. The diode prevents current from flowing in the opposite direction to the battery
- On the esp, we solder wires and a 5.1 kOhm resistor (there are resistors included) or 5.6 kOhm. The resistor is soldered to contacts A0 and GND. Solder two wires from contacts A0 (brown wire in the photo) and to +3.3V (black wire in the photo) and stretch to the very bottom of the cylinder body
- We install a 5.5 mm power socket connector into the housing hole, solder the wires from the connector to the step-down of the GSMIN MP1584EN DC-DC voltage converter, and from the step-down to the esp. On the step-down we set the voltage 2.2-3.3v and check the motor power. If the lever is pressed hard into the limiter and starts to crack, then lower the voltage to 2.2V and it should be so that the lever rests against the limiter and at the same time the motor does not have enough strength to push the lever and could not wear off the gears
- We stretch two wires from contacts A 0 and +3.3V and apply hot glue so that there is a circle in the center and an arc at the back. I filled the wires with conductive glue - there is no need to solder.
Important! Conductive glue does not fit well on the smooth surface of the plastic, it begins to swell and peel off. Be sure to sand or scratch the smooth surface thoroughly, then the conductive glue will lie perfectly
- We print the platform on a 3d printer, install 2 magnets to enhance magnetization, install a resistor in the hole and cover it with conductive glue. The consumption of conductive glue can be different, therefore, if there are several platforms, it is advisable to take several pieces. I took 5 packs. The STL model can be downloaded from here
Hi,
I have made my glade automatic air freshener smart.
The PCB from the post above was not the same as mine.
The decision was to use only the motor of the air freshener and get rid of everything else.
My approach:
- Control the dc motor by ESP8266 with DRV8833 h-bridge and a dc/dc buck converter in between to get 3V.
- Providing a “Spray” button to trigger the air freshener.
The repository is an early state.
Things to do:
- Add Spray counter to ESPHome YAML
- Add internal boolean to avoid a new spray command while moving the motor
- Create automations like:
-
- Spray if toilet was flushed and door opened and closed again (will be handled in Home Assistant)
-
- Time scheduled spraying at Home Assistant
The documentation can be found here:

Very interesting… How do you monitor flushing the toilet? What kind of sensor do you use…?
Currently it is not installed but I think an aqara door and window sensor should to the job.
The sensor will be opened, two reeds installed in parallel instead of one. The magnets will be attached at the toilet button plate.
I do not know how it works at your home, ours look like that:
O.K. You have build-in wall system… In my case all is ceramic and outside (old fashioned type)…
Very interesting. My region only have this version of the Glade and I have search the net to find one post that said it is not possible to quite challenging to to be smart. I used a relay to intercept the power. Where it turns on for a 10 seconds, spray and shut off. Works great, but it still uses the battery.
I would imagine my unit version would still work with your setup since it does have a motor? The little issue I would run into is that the unit is quite small and I will need to mount everything outside.
I think it should be possible.
Not sure which motor is used (could also be 1.5V).
First you should measure the voltage on the motor when spraying.
DRV8833 can operate with 3-10V.
I’ve found the post. The shell is different but the internal looks the same down the the pc board. The post said the motor to be 2.5v.
Hey there,
alternative approach: I’ve hacked an Air Wick Freshmatic. The 3D printed cover houses the ESP, which switches the device on and off by acting as a AA battery. The device releases one spray 15 seconds after the power was connected. Assuming this delay is acceptable to you the electrical solution and further HA automation is rather simple. Works perfectly in two bathrooms for the last two years. 
Happy to share details and code.

Very clean setup. For this particular Air Wick model without converting it to smart, how does it activate?
For my model, it spray once motion is detected AND every 30 minutes( something like that) throughout the day whether it detects motion or not. Marketing scheme to make you constantly buy the refills.
This particular model sprays 15 seconds after activated, then every 30min or so. This initial spray is what made this clean setup possible. From Home Assistant I simply turn the device on when no one is in the room and turn it off some time after. If you ignore the 15 seconds you could say I have direct control of it spraying.
Here’s a simplified copy of my rules.
On:
- trigger:
- platform: state
entity_id: binary_sensor.bathroom_door
to: "off"
for:
seconds: 5
condition:
- condition: state
entity_id: light.bathroom
state: "off"
action:
- service: switch.turn_on
entity_id: switch.airwick
Off:
- trigger:

- platform: state
entity_id: switch.airwick

for:
minutes: 30
condition:

entity_id: switch.airwick
state: "on"
action:

No magic on the ESP either. It’s running standard Tasmota with one “Switch” GPIO.
Hey Daxi,
This is great, thank you so much for sharing. I’d love to see more pictures of the inside as well as the reassembled Air freshener. For example, where does the USB cable enter the air freshener?
Thank you in advance!
@rodri2566: Project is updated and pictures of the final air freshener added:
- Added spray counter as readonly data
- Added reset button to set spraycounter back to 0
- Changed timings for glade cans (previously worked fine for airwick cans but not glade cans)
- Spraying logic moved to a script
- Avoiding multiple script executions by the button which avoids motor stress.
- Moved ESPHome YAML to its own file
Thank you so much for sharing @Daxi . It’s a very elegant solution, both in terms of hardware as well as software.
Hey Daxi.
Added a lock to your code at the end of 2400 sprays and the presence of a spray in the can.

I’ve received all my parts and have done soldering. When I test the motor, it is turning the opposite direction. I am confused of what to change as I have tried a couple of ways, but the motor does not change direction.
I have tried swapping the gpio pins on the d1 mini. Change the pin id labels in the config file.
