I am pretty new to my sensors. Definitely new to creating pcbs. But I did manage some how to create a small pcb in eagle, did the laser toner transfer method and etched it at home, drilled the holes and soldered it all up and go it working. Next step is to design and 3dprint my custom case and get it mounted.

Thanks for all the help you guys have given me.

Hey Guys,
Figured I would try to start a new thread for this. Last week I posted the code so far as I have for the milight integration in to 2.0 here.

https://github.com/brunkj/MySensorsMiLight

I have not been able to work on it since. If anyone wants to take a crack at it and has some milights, feel free

I think this could be a very cheap way to replace hue and the $$ that goes with it.

My uploaded code as of now will allow you to pair with your bulb, you have to send the "ON" command with in something like 3 seconds of turning on your light. That's how it pairs. Once you pair, you can send on and off. There is code there from previous versions for some of the other stuff like color change and dim. But I have not figured that part out as far as how I need to send the data.

If @ted is still around he may be able to help even more so since he wrote the original. Im just hack jobbing his code up to 2.0 lol

So, I have looked in to this. I even had a fitbit that i was hoping to use to determine if I fell asleep at night and turn off lights in my home automation system.

The down side I ran into is this. I had fitbit setup with ifttt since that was something it could interface with. The sleep detection worked. HOWEVER. It only actually posted info to IFTTT when you woke up, at that point, all sleep related data was submitted. So it didn't track it real time.

I have been looking in to how to integrate sleep in to my HA but also like you mentioned quality of sleep. The fitbit utilizes motion to determine "restless" sleep. Attaching a bunch of sensors to myself doesn't seem like it would yield comfortable natural sleep. So potentially stuff like a mesh of piezo sensors under a mattress topper would work. that would detect when the values change indicating turning, movement.

Temperature should be easy (fitbit probably does it, i had a cheap one so it did not).

If you want to get crazy (which if i had time i would go this route) you can get a fitness watch with a certain chip in it, and reprogram it.

That's what he did. This could be REALLY REALLY cool. You could code in your own parameters and what not, since it's bluetooth LE you could track it via phone or just remote sensors.

Once you have some basic "restless" night tracking you could do some experimenting (even with the fitbit).

• track your sleep for a week or 2 to get a baseline of how much time each night you sleep "restless"
• change thermostat temp up/down - track again and compare.
• monitor body temp and see if warmer/colder = restless. find sweet spot.
• integrate body temp monitor to HA system to control thermostat to keep you correct temp

If you make any progress, definitely let me know, i would be interested to see what you come up with!

any plans to add an RTC on this and be able to timestamp the log entries? I have some sensors that only wake up and do readings every 90 minutes. But sometimes they just stop doing it. So time stamps on the logs would be good to see if there is anything happening right around the time it stops reporting.

So I have a new development. I noticed something strange. The mysgw stopped again today. I went digging through the syslog around the same time. Didn't see anything just before it went offline, but i did notice that shortly after it went offline it said that the carrier dropped for the nic.

So i decided to check a few other times in the last 48 hours and sure enough. Same thing. It seems that something is causing the nic to think it lost it's connection to the switch. The mysgw seems to go in to a weird state. Not sure what error checking is in it or what i could do to log more since i am already on debug for the logging of mysgw.

Next step i guess will be instead of dhcp reservation ill static assign it. See if that changes anything, and see swap network cable. Maybe hard set some things like the speed/duplex on the switch.

Just figured i would throw out my latest finding.

Ok I got it to work. I misunderstood how the interrupts worked. Got it now. The culprit was the if statement detecting if the state changed. Since the state was being maintained while sleep, it wasn't firing when I pushed the button.

Thanks for everyones help!!

@zboblamont good to know! I have 2 florescents in my garage that i swapped for LED. These didn't need to bypass the ballast. Might be worth a test to swap those out for the ones in the bathroom (where i see the most interference)

Guess i know what im going to try when i get home!

So a little new info. Last night i had the lights turn off with the door closed, and no one turned on/off the kitchen/bathroom lights. But what did happen, I turned off a little space heater in my room. When i turned it off, the lights off. Finding this very interesting, i grabbed my phone (in the dark) and check the HA status. The motion detection was triggered... ok... so maybe it's not the PIR/repeater that's the issue...

It's the LIGHT MODULE!! There is a good chance that the power fluctuations aren't messing with the repeater itself, but actually resetting the arduino with my lamp relays. I think this weekend i need to pull that out, check the code to see if i am saving state to eeprom and also throw some capacitors on the incoming power to see if that helps.

Is there anything like this going to be done in the US? I would love to help/attend.

@mfalkvidd roger that

has anyone thrown this in a docker yet?

Ah nice. Thanks for the response. I used to get environmental fluctuation's with my ultrasonic sensor I used. I couldn't tell if it was from the air temp between the sensor and the top of the water changing or the barrels themselves heating up and slightly expanding and contracting in the sun through the day or both.

But it was small like you said so I wasn't concerned. I have 4x55 gallon drums (around 832 liters) total. So I am wondering if maybe pressure sensor would work..

Thanks for the idea. Definitely interested in testing it. I have ball valves already on the barrels so it won't be difficult to make a little connector rig to test

@CrankyCoder ok. so i made myself go learn something new. Water Pressure Depends Only on Depth, Not Container Shape – 14:57

So IF I used a pressure sensor like the one mentioned above the pressure of 1 barrel half full is the same as 4 half full connected. So... It would seem that I COULD do measure my volume with 1 sensor and taking in to account how many barrels are open. (I have shut off valves so I can disconnect to repair/clean as needed)

Random question. I have 4 rain barrels all connected via connectors. Would a pressure sensor like this work for measuring the liquid in that? Not sure how that would affect the reading.

I have done some digging around and and I am not 100% sure or not but I do not recall if the relay module in the node is optoisolated, so that could be part of the interference if you think that could be the issue. I am pretty sure the 5v power for the relay module and the arduino are coming from the same 5v psu BUT I am 99.99% sure I do not have a cap across the 5v/gnd on the relay module, so I guess I could pull that module out and see about replacing it with an optoisolated one (if it's not isolated) and put a decoupling capacitor on the relay module itself.

Just some thoughts.

I would need to leave something connected all the time wouldn't I? Hooking laptop to the arduino would cause the reset?

The relay module is a purchased 2 relay board for the arduino, 5v logic.

I have a 2 relay node in my master bedroom running 2.3.2. Gateway is pi gateway running the same version. Node is built with the easy/newbie board. It’s a decent distance away from the gateway, periodically something happen and I guess it stops being able to communicate. But oddly enough, it never seems to try to reconnect. I thought the built in watchdog should get it to go back to find parent or something.

If I unplug the module and plug back in, reconnect, all is well.

Just wondering if anyone has any advice for getting nodes to retry to connect to gateway better. I feel I’m missing something simple in the stability aspect here.

I am finally getting around to trying this out. I was playing with just trying to see if i can get the pulses. First thing i did was take an old compass and put it beside the meter and had someone turn on the water. I could definitely see the compass needle pull a little as the water was flowing. So I assumed that pull was enough to be detectable with my hall effect sensor. I have tried a couple, and just can't seem to get it to pick up.

If i use a magnet, simple code will detect the pulse and the green led on the sensor lights up.

But no matter where I put that sensor near the meter it just doesn't seem to detect it. Not quite sure what's happening.

The meter i have is this one.

Not sure if anyone has any recommendation on which hall effect sensor would be the best for this but ill take suggestions lol

My sensor I am testing with is
3144E Hall Effect Sensor

Doesn't have a sensitivity dial but the recommended one on this build page didn't either.

I second this. I went the mqtt route as well. Auto discovery is cool, but i wanted some additional control. My openhab 2.5 I don't use the UI at all. I just all flat files. This is a preference for me. I also use the VSCode extension for openhab and it works BEAUTIFULLY!

Do you have any install documentation for it? Any docs for integrating into existing snips setup?
