I've been tinkering with 3d printing for about a year now and never had any experience before.

Tried most softwares out there that are free and seem to allways comeback to fusion 360.

For slicing I like slic3r PE in the free tier, even tho its interface looks dated it has some very nice features and handles material/printing profiles really great.

But if u want an all in one package it's simplify 3d. Even tho you don't get the same control as slic3r and it doesn't handle material profiles as good.

It has a clean interface, great gcode preview and a few killer features like custom supports (yes there are other slickers with this aswell) and multi processing that lets you switch profiles anywhere in the print or model.

Yes it's a big price now days for a piece of software. But if you are going to use it alot it is well worth it's price.

I must have been drunk when I ordered this. Any idea what I have ordered? I ordered thru dirtypcbs somehow.

Does look a little bit like this PCB but not really. Have I found a early version and drunk ordered 10 of em?

Extension cord it is!

Just started my project of monitoring the water level in our water tank. I have bought that waterproof sensor from the hardware guide but it only reports around 2 meters in testing.

Problem is that i have about 8 meters down to the water level so i either need to lengthen the cable to the sensor by about 6-7 meters down the hole or find another sensor to do the job.

Any idea? this will not be battery powered so no issues there.

@tekka
How about I'f i replace my serial with a Ethernet gw?

Do not want my pc running all the time. Just to debug

Ok this might be a realy stupid question but im what you call a "nuub"

If i want to monitor my current setup (serial gateway on a pi3) on windows/mint. Do i build another gateway and plug it in the pc?

Sorry if i missed the instructions on this

@sundberg84

Yeah trial and error I guess. I have an outlet outside that I could put a repeater in so i might start with that one.

And caps are on all my nodes so far

Thank you
Where can you find these changes?

Heres the deal
I dont live in a giant house but the walls of the house are pretty thick (inside around 30cm and the outside walls are around 45-50cm) the outside are mostly made of wood, have one wall around my heatersystem that is concrete.

I spent days debugging a masterpiece of a mailbox / light sensor that was battery powered and when it finaly was soldered and working as i wanted i happely strolled down to the mailbox (around 50 meters from the house) to install the thing..

Aaaand lost contact, rebooted, walked 10 meters up, rebooted, 10 meters up and so on until i basicly where at the otherside of the wall to my gateway.

So i searched for the solution and found repeaters!
So far i have built 2 of them and placed em togheter with nonsleeping PIRs. And i think they are working, no idea how to tell if they actualy are repeating anything.

The plan is too build a few more in the house and atleast 1 outside where i have power, just to be safe that the range is optimal around the house and a bit outside of the house.
But i read a post in here about repeater looping problems and such so is it a bad idea to install extras even tho it might not be needed?

I need to check my node. It Constantly shows 80-90%. Have switched forks and plant same number. If I pull it out of the dirt it gets to 0%

Using only the fork no board in the middle with the alternate current sketch.

I rebooted domoticz and it got the right values for the childs

Any tips of geting rid of unwanted values from the child's here?

Have been debugging and experimenting with a lot of different sketches and I finally got it to work. But old values are still in there.

not sure of link worksge. on phone atm. will paste it from comp later if its not working.

@mfalkvidd

Hmm i have a combined sketch of the pir and dht example that works fine on a node that Can Sleep for a bit and interrupt with change on the pir.

But if i take that sketch and change the Sleep with interrupt to a wait(sleep_time) the pir is not registrering movement between wait Times'.

FIf i remove the wait alltoghter the pir is reporting the status every ms instead with the result that the dht can't read the temp!

About to built a dht / pir / repeater.
Since i cant Sleep it do i need to change all sleep with wait?

In the dht example there is a Sleep to let the sensor settle before Reading. Should this be a wait instead then?

This is what i did, the box should be the mailbox right now but aprently i need to build a few relay nodes aswell.

@rnollen

I am about to set a lux sensor outside any day now (as soon as the debugging is complete that is).
And i am going to place the board inside a glassjar, drill a hole in the top and seal the cables using a gluegun or similar.

Should be waterproof then right?

I think i solved it by replacing the tripped code with this modificed code from
https://codebender.cc/example/MySensor/BinarySwitchSleepSensor#BinarySwitchSleepSensor.ino

{
uint8_t value;
static uint8_t sentValue=2;
// Short delay to allow buttons to properly settle
sleep(5);
value = digitalRead(BUTTON_PIN);

  if (value != sentValue) {
 // Value has changed from last transmission, send the updated value
 send(msg.set(value==HIGH ? 1 : 0));
 sentValue = value;
  }

@mfalkvidd

Thanks alot for all the help with My newbie arduino questions. Ill try the wait statement later

Well it seems to be the debounce thing that is Messing with me.

How can u remove false positives when battery powered?

Im trying to combine some sketches in hope to create something that should monitor my mailbox and read the light outside while powering the thing by battery!

Right now i have basicly cut and pasted the 3 sketches for the switch/battery power and light sensor and have em hooked up on a uno with breadboard. Using USB connection to power it.

Started with switch and sleep interupt and it worked fine. Removed the debounce since it couldnt be used while sleeping aprently (nuub here)

Added battery sketch and it seem to be working..

THEN i put in the damn lux meter and all hell broke lose.
Everytime i trigger the switch now it starts sending status like crazy to the gw, im talking light speed.

And while its sending and the switch is seperated it allso gets alot of false positives (or negatives the way you look at it)

The Battery voltage can be ignored since it isnt even powered by battery or have anything from that hook up on the breadboard.

And the other thing i noticed is that if i leave the switch closed and let it do its sleep time thing. It reports every 5 minutes! how can that be when i have put the sleep time to 1800000ms, that should if i counted correctly equal to a reading every 30 minutes?

It seems to be reading the lux and the switch right in domoticz but as said the switch goes on and off.

Below is a snipped from serial monitor when it goes haywire.

@jpaulin

I havent built much yet so i gain nothing by replacing my serial gateway with a mqtt?
using domoticz/rflink

As a newbie that only so far built 2 sensors and a serial gateway.

What is better with this kind of gateway?
Should I build one instead of the serial one I use now?

@mfalkvidd

Ok
But Its normal just to lower by a few percent in a few days time?

Small problem with my plant sensor. Used only the fork and the reverse polarity.

But the sensor is reporting around 80-70% all the time, alltho the plant is pretty dry.

When i remove the sensor from pot it shows 0% ?

Can you calibrate the fork somehow?

Sorry for nuub question but can you use a pro mini 3.3 för this?
Or do i need a nano or pro mini 5v?

@flopp

thats the irq pin in the radio post.
Not used by the radio

@Stric

Does reverse polarity really help with corrosion then? Maybe it has something to do with that.

Yes i do.
This is like going back to school... but fun!

Realy n00b in electronics here but do you need to use those exact values of the resistors when hooking this up?

@sundberg84
Will look into that, i have a UNO lying around aswell so prehaps ill experiment with the bootloader burning eventually.

@carmelo42

How does this work when using a booster?

I made a node with 1 fork and it works great!

Any tips on how i can use more than one fork to monitor say 3-4 plants?

@Tetnobic i tried this and Ended up with a soil sensor that didn't display % but something called cb?

But yeah it works.

If I use more than one sensor for this. It still will only monitor one plant right? Or can I say monitor 3-4 plants with one node?

If i want to update the gateway to 2.1, do i just need to download the master and reupload this scetch to it?
Do i need to do that to all my sensors aswell?
i am on 2.0 right now

You lost me at bluetooth beacon?

Me personally is using the app but wifey and kids ain't really as interested as i am

So therefore I would need a indicator of some sorts around the mailbox that is about 30 meters from the house in the road up to the house.

Maybe a solar led light or similar to light up? Or a flag on a servo?

Will start with building the switch and figure out the indicator later.

Nuub here..
Thinking about building this in my mailbox..
AND if possible set a green light diode to start light when box is opened and stop when its opened again.

That way i would see when i come home if someone has opened the mailbox or not.. Sure push notifications work aswell but it would be a nice touch for the wifey

Hmmm found out that it only will recieve data not send it.

Oh well, another gateway it is

First off im fresh of the boat and is about to begin my first projects.

I have a few 433mhz switches in the house already and zwave is expensive i went and bought an arduino mega and a 433mhz transmitter/reciver and hooked em up last night.

Using em in domoticz.

The question is.. I have a order of alot of stuff from aliexpress for mysensors projects incomming.
The plan was to build a usb gateway and use it on the same raspberry as my RFlink gateway.

But now i see that the RFlink supports mysensors since oktober 2016?
Does this mean if i add a 2,4ghz trancever on my mega i can controll both my 433mhz AND the mysensors network from it?

Ive tried googleing and searching but i cant get any clear answer.
Anyone with knowlage about this

Finaly got it to compile.
I tried the library link above but no go, cleared out everything about ardouino on the pc, no go.

I finaly stubled onto this:
https://github.com/mysensors/MySensorsArduinoExamples
Downloaded all the expample libraries, loaded the scetch and it worked!

Something is up with the linked library on this page i think

@mikeS thanks alot!
I'll keep that in mind. Should be getting my "starter kit" order soon from eBay so we'll see how it goes

@mikeS

Ive tried to reinstall and start från scratch but i guess i Missed something.

@Jim Danforth
Getting the same, have tried a number of different DHT libraries and cant get it to compile.
