I had a test setup that also had a sensor looking down so I could 'see' if my car was parked in the garage or not.... if distance < 1m == car parked.

My garage door opener is directly above my car when its parked.

Maybe bescause he had the parts around?

Or this way you can check if it's moving up or down as it's fixed on the rail and senses the door moving to or fro ?
Edit: he explains in the text itself.

Some more info on the cube can be found at the homeassistant forums

@martinhjelmare
Any new developments regarding this topic?

@AWI
This is how it looks like at the moment.
Still taped together as everything is beta stage.

@AWI
Thank you for answer.
See this link for an project based in this.
Its basically a scène controller in the shape of a cube.
I got the idea from the original poster in the thread over at home-assistant.

https://community.home-assistant.io/t/rubiks-mood-cube-magic-cube/9965/8

I will post a BOM, sketch and pics if someone wants me to.

@AWI
Is it possible to sleep the node and wake it up by external interrupt ?
I have a use case for this but it has to be battery powered.

@pjblink :
Did you use any fuses between the 240v and the 220 > 5v module?
Could you post a picture of the backside of your perfboard? I'm interested in how you wired everything up

I've seen this when I set the radio power to max and power the LCD via the nano at the same time. The LCD takes to much so the rest doesn't work....

How to this sensor knows where is the sun?

I guess 4 ldrs with a cross between ?

@AWI said:

@Fat-Fly a sun panel tracker based on this circuit is in place on my roof. My major issue is mechanical. How to seal the (stepper) motors from the environment.

I once saw someone on YouTube that mounted them in pvc pipe with a cap.
He used electric drill motors for the actuators though.

Is it important to know that all the chickens are in the coup before you close the door or are we just assuming they are all inside at a certain time?

I use a light sensor and close the door at <5 lux. They are allways in by then.

I've had a similar setup run for over a year. Last week my ln298 broke so the door doesn't open and close anymore. Waiting on spare parts. I have guillotine style door with reed switches on top and bottom.

Kelvin or Celcius?

Nice project, I think I might use it for my pool...

where did you get the laser cut acrylic?
Celsius
The acrylic was cut by snijlab.nl
A Dutch company.

I use this for my pool (and DIY solar pool heater)

my bathwater sensor

waterproof Ds182b & TM1637Display

use it with domoticz & edomoticz Homebridge plugin so Siri can tell me if my bath temperature is hot enough or not

9v at the moment because no regulators at hand...
case is custom lasercut at snijlab.nl

Very nice solution.
One question; does the using the timer function for temp, hum etc block the processing of incoming messages from domoticz?
i mean that during the temp , humidity or batpercentage calculation no icoming messages from domoticz are being processed?

i'm getting this error:

[code]
open_Mi_Light_Controller_repeater.ino:3:23: fatal error: nRF_24L01.h: No such file or directory

I think you have the same challenge as I do. See my pulse water meter topic here:
http://forum.mysensors.org/topic/2101/pulse-water-meter

i'm running v2.3219 on my synology. i think this is a beta release?
i think my strange values are due to trying to add the values by json, this results in adding it to the todays volume and not resetting the total count?

furthermore the positioning of the tcrt5000 is critical in preventing false pulses and this is what is happening now with my meter i think... the small led light on the sensors blinks sometimes very weak when the wheel of the watermeter isn't even near the led....

I ultimately resolved it by editing the sketch setup() to send the true meter value to the gateway before it gets requested and sent again by the loop().
I did this once, removed the send and uploaded the sketch again.

But now I can check between the mysensors and the real meter I see that the data is off...must investigate further what is going on. In my test setup the pulses get counted like they should. (I tested by moving my finger in front of the infrared led.) I suspect the mounting of the sensor on the meter is off somewhere and generates duplicates or erratic pulses?

i tried again the following:

• Deleted the sensor
• Go to unused devices and add it again (total and day value are now 0's)
• Unplug the my sensors watermeter node
• Update the device in domoticz via JSON with
  http://10.0.1.13:8084/json.htm?type=command&param=udevice&idx=339&svalue=27808
• Plug in the my sensors node.
• After the first update (30 seconds) the device in domticz shows this:

then i changed the child ID in the sensor sketch, reuploaded, changed the value via son and got this:

It keeps getting stranger to me. I deleted the mysensors hardware and all devices. Added the hardware again and the water sensor received a value of 269 pulses from the gateway?

I'm having trouble with the pulse water meter values in domoticz.

A newly added sensor starts with value 0.803m3 and not 0

If I enter a new value with json URL , http://10.0.1.13:8084/json.htm?type=command&param=udevice&idx=290&nvalue=27736&svalue=27736;27736

the value gets overwritten with the 0.803m3 every time. In the sketch the comments say it gets the latest pulse count from gateway when it powers up?

But the value 0.803m3 is not the value of my water meter when the node powers up. Where does the 0.803 come from?
