What did you build today (Pictures) ?
-
I guess because you can do pretty much everything you want instead of being bound to what Domoticz can do
-
I have been using influxdb/grafana for the last year or so, for logging data and presenting it, so no need to use domoticz for that. Over a year ago I injected nodered into the stream, so it sits between mysensors and domoticz, and was used to route things around (And make some fake sensors for domoticz).
For the dashboard part I have been developing my own solution. First it was running within domoticz as a customized dashboard, but I moved it to Angular instead, with a strong dependency towards domoticz, as I could query that to get sensor values. Lately I had moved on to use MQTT for the dashboard (and internal node-red data routing). There I can get persistent data (retain) that keeps the latest data on a given topic. Then my need for domoticz went away there..
The last thing I then used domoticz for, was the automation rules for turning on / off my tv when the chromecast was activated, and control a couple of LED strips according to the state of the chromecast (playing / paused etc). With that moved to nodered, then domoticz could be turned off.
The complete software stack is a bit larger, than with domoticz for everything, but it is much more flexible, than what I could achieve with domoticz.
also it brought in a couple of needed updates for my node-red mysensors nodes, so that was a "bonus" as well
-
@tbowmo interesting indeed, tnx for sharing. Currently I still use Domoticz for the API Logging is done with INFLUX and Grafana. However in addition to Domoticz I use Pass2PHP. I can now control everything with PHP. PHP seems pretty common so a lot of examples I can find online ;-0. I am a complete MQTT / NODE-RED NOOB.

So start playing with it to become a Node-Red/MQTT Fanboy!
-
It is always those last connections...
-
@sincze well you're half way there, already got influxdb implemented
NodeRed is pretty easy to work with, and MQTT is (almost) just start and forget with mosquito. Just a messaging channel that you can hook any listener into, like python scripts, angular5 web apps etc.

Today I built auto-detection of missing MySensors keywords. The build system will complain if someone adds a new keyword to the Doxygen documentation but forgets to add it to keywords.txt.
This is what the output looks like on the current code base (we're missing a bunch of keywords):
This is the code change:
I have also added those missing keywords to keywords.txt, so now they'll be highlighted properly in the Arduino IDE.
Thanks to Anticimex for assisting me in working with the build system.
-
One more build for today: building the raspberry pi gateway.
I often need to test different settings for the Raspberry Pi Gateway. Running make after just changing one parameter in the configure command (for example, turning on or off interrupts for nrf24 or changing the PA_LEVEL) results in a 1m 13s wait on my Raspberry Pi:
I installed ccache using these instructions and now a make with the same type of change is done in 31s.
Not that much of a win, but it saves a lot of time when trying many different settings.
-
did you cut the compile time of the gateway?
-
@gohan yes?
-
@mfalkvidd on my Pi3 it takes 40 around seconds, are you using an old Pi1 ?
-
@gohan no, I'm using a Pi3.
-
Today I finally got my thumbs out and upgraded my plant monitoring to MySensors 2.x (from 1.x).
Updated sketch is available on Github: https://github.com/mfalkvidd/arduino-plantmoistureResult: I really need to water my plants
But the 2.5 year old batteries are still going strong.
-
Tonight some more PCB design:
-
@sundberg84 I will throw my two cents in on the design. An issue that I had brought up on previous revisions had to do with capacitors. On the Rev 9 and below boards, your capacitor footprints were pretty much all for flat ceramic capacitors. While I was able to make it work for the couple can style electrolytics that I used, it wasn't quite right. Now on this revision, I see that all of your capacitors have a can electrolytic style footprint. I think it needs to be a mix. The 4.7uf and 10 uf capacitors should be can style footprint, whereas your 0.1s should be non polarized ceramic flat cap footprints. The flat pack ceramics I think have a wider hole spacing.
Again, just my two cents
-
@dbemowsk the positive with polarized footprint is that you can use both and it's very easy for a newbie to see which one is Gnd. You who are more experienced can determine if you want to use a flat unpolarized cap.
-
This evening I spent a few hours finding more MySensors keywords that exist but weren't highlighted.
I found about 20 that were documented but not highlighted, so I added them.I also found 3 that weren't documented nor highlighted. I have created issues on github to document them. Help is welcome. Documenting the keywords is an easy way to contribute to the project.

-
@sundberg84 one of the 0.1uf caps that i use has short leads and wouldn't fit that hole spacing. They are higher voltage capacitors that i bought years ago for another project that i am trying to use up. I do see your point though.

What kind of components is this running on? I am having trouble getting my batteries to run even 2.5 months (or 2.5 weeks for the outside temp sensor...)

@maghac see the link in my post for full details. But basically it is just what's recommended on the battery page. Arduino pro mini with power led and ldo removed, bod set to 1.8V, powered by 2xAA.

@thucar what display do you use and where did you buy it? What library did you use?
-
@dirkc the display is a JLX12864-378 off a chinese “component tester” kit I had available. Using the u8g2 library to run it.
-
Today I built a led dimmer and motion detector for my kitchen. Running on 12v and a led list of about 2m.
Everything is built on my MysX led board and it was so easy to assemble everything and it's really small.
I have documented this project and will show you in a video when edited.
-
Today I built a new Ethernet Gateway.
Using a Freetrionics Ethermega - Fixed SPI bus, so no soft SPI and I can use MY_RX_MESSAGE_BUFFER_FEATURE. PoE, improved voltage regulator design so I can run the amplified NRF24 with MY_RF24_PA_LEVEL RF24_PA_HIGH.
Under the radio is a small prototyping area with capacitor for the radio and an ATSHA204A - because one day I swear I will implement signing.
Slightly modified Gateway sketch that writes successful DHCP IP addresses to EEPROM. I assign a static address on my router. If there's a power failure, the gateway will start up with last address - router takes ages to come online.
Fired up the X-carve to cut the aluminium chassis, which has added benefit of shielding the NRF radio as well. The complicated cutout on the front was to allow air intake for the fan. Was supposed to just be a grille, but after a couple of beers I got too cute for my own good. Took 2 hours to cut that.

Today I have finished work on control center for my smart home. The box includes a Raspberry Pi 3, gateway, ethernet switch, power supplies 5V and 9V. Audio input jack, ethernet and AC line cabels out from the box. Maybe, a GSM module should be included to the free space too (i will thinking about...). I am going to install this box in the near future.

Today's work:
- Fixed https://github.com/mysensors/MySensors/issues/1096 (PR in progress)
- Fixed 60+ spelling mistakes in the example sketches https://github.com/mfalkvidd/MySensors/commit/6e7ee6ab30d503a6f288553689fdfbe645c931e6 (will submit PR when above PR is done)

My friend had a leakage from the water heater, luckily he was around (and renting) so not much damage was made, so inspired by the incident I made another water leakage sensor for water heater (reusing the code from my previous "ribbon cable sensor" )
Then I have an "alarm" flow in node-red (via openhab) which blinks all lights in the house, sends notification to mobile phones with high priority etc. Which brings me a lot of joy when all works fine (and annoys my wife, as usual)...
They are so easy to made that I might as well make a few of them just for convenience and "feeling rich with sensors" if you guys know what I mean
-
@dakipro what kind of setup do you end up with regarding bootloader / bod? What do you use to reprogram the pro minis bootloader?
-
@sundberg84 these run great on 1.8v BOD with some bootloader I found on the web (linked in the last post here ).
I use uno to flash the bootloader (tried with some IVRs but never got it to work, so just dedicated one uno prototyping hat for flashing) and then upload the sketch with IDE.
They are reporting battery from 2v to 3v (0-100%), and previous linked node is now reporting 51% of battery after 6 months, with sensor check every 2min and hearth beat every 4h.

Installed z-wave roller blinds (discussed on this topic) from Swedish company m.nu .
If all is great, I will order three more motors (and two knobs/switches) for living room and terrace doors (which should also automatically keep the shades open if doors er open, to prevent damage).
Made a basic node-red flow that uses xiaomi lux sensor to get them down, but ultimate goal is to have them understand when the light is very bright and when it is "cozy", perhaps even knowing to get the blinds just low enough. Found one good explanation on the internet, will check it out (perhaps use multiple lux sensors strategically placed around the room to determine sun position and strength). Any tips and tricks?

I printed a small box and put my first "22" board in action on my entrance door. So far so good it's reporting the status reliably, and looking really tiny. A big difference with my first sensor 2 years ago in a big generic project box.
Just need to clean the glue left from previous sensor now

Not really, I posted about it long ago here (https://forum.mysensors.org/topic/7836/what-did-you-build-today-pictures/136) It's just made for me to play by making a sensor as small as possible, but it's pretty hard to solder and with CR1632 and nrf22 the battery life won't be that good (around 1 year) so I don't think I'll publish it.

These arrived today...
New gateway and nodes with signing is first on my list.
-
Built half of my dutch bucket system. Namely the drain part. Irrigation to follow.

Working on setting up a new work bench in my back room in my basement where my HA equipment rack is. I wanted to build a case for my serial nRF24L01-PA-LNA gateway built on a rev8 Easy Newbie board. I just had the board sitting on a shelf on my rack, and now I want to mount it on my MDF board with all of my other equipment. Here is the design that I came up with for the case.
This is the inside bottom of the case:
And here is inside the top of the case:
It has a spot for 3 - 5mm LEDs for the transmit, receive and error lights. There is a hole on the right side of the case for the PA-LNA antenna connector. The oval hole on the lower right side of the case is for the DC in jack. I had one of these in my parts bin:
The hole on the bottom right is for the FTDI adapter connection. I am using one of these adapters that has a mini-USB connector:
I have the case running on the printer now. I will post pics when it is done.
-
@dbemowsk very impressed by your openscad designs, as always
-
For anyone interested, here is an OpenSCAD rendering of the MySensors logo:
I tried posting the OpenScad code for this, but it is too long to add to a normal post. So here is a link to the OpenSCAD file.
MySensors_logo.scadSpecial thanks to @hek for giving me the .svg file that allowed me to create this. I would be curious to see peoples uses for this.
-
So I tried printing the cover for this with my original design using Cura as my slicer, and I couldn't get the logo to print right, plus the text under the LEDs was a bit too small. I then modified the design a bit and made the logo and text a bit bigger. I again tried printing it using Cura, but the logo still was missing some lines in the body. I then thought that part of the problem was the slicer I was using, so I tried it using Slic3r and I have to say, the logo came out MUCH better.
I ended up losing the Y in "My" Sensors and the ending "t" in "Transmit", but I am going to use the case the way I currently have it. Now I just have to assemble the new gateway. I am planning on making a whole new gateway and trying out the new 2.2.0 library. Hopefully my older 2.0.0 nodes will not have any issues with it, but that is why I plan on keeping my pro mini from my 2.0.0 gateway so I can revert back to that if I have to.
-
Built case for soldering tools, to easily move them out of the way.
Not really, bought it on banggood and asked wife to assemble it (she likes those type of projects, especially if the office might look a tiny bit cleaner) https://www.banggood.com/DIY-Self-assemble-RC-Model-Tools-Case-Screwdriver-Box-Gripper-Package-Plier-Stand-Retro-Style-p-1257252.html?cur_warehouse=CN
Laser cut plywood(or something), looks quite nice I think. I will order few more when they appear in stock.
-
So here is my contribution to this tread: a differential drive "brain". A work in progress:
-
Finally finished my 2.2.0 gateway and have it mounted in the new enclosure. It appears to be talking to my 2.0.0 sensors just fine.!
-
Another motion and led strip node.
-
...and deployed.
-
Nice, maybe add a diffuser? I've found that greaseproof paper (smörpapper in Swedish) works pretty well.
-
@gertsanders what is that?
-
@sundberg84 Nice. I was wondering if I had an use for these. Now I want them everywhere!
-
@nagelc - easy to hide, looks good and awsome as night-lights for the kids. Its also a bit woav factor connecting them to a motion detector so they lights up when someone walks by.
-
Bathroom controller. It consist of a relaybox with a HLK 5v power source, it's hidden in the closet. Then I have realy to light, nightlight, mirrorheat, and extraction fan
And then the controller it self it's a Wemos D1 Mini Pro, Si7021 Temp/Hum, sensor and a PIR HC-SR501
3D file is created with Freecad, STL files are available here:
https://www.thingiverse.com/thing:2890456
-
@bjacobse Nice project. I like the 3D printed wall box. have you given any thought of having separate control of the lights and extraction fan? The reason I ask is that it may be beneficial to use the temp/humidity sensor to determine when the fan runs or gets shut off based on room humidity. This would be useful to reduce the chance of mold brought on by excess humidity.
-
@bjacobse don't you get false pir detections with the wemos that close to the pir sensor?
-
@dbemowsk Thank you
For now as it's in early stage, I use the left switch to switch on (when I goto shower)on manually the fan, mirror heat, fan, and light and nightlight for 10min.
the right switch is only to start the fan for 5 min
I have not yet added humidity to start extraction fan automatically, but yes I will add this to the ESPEASY, rules
-
@gohan
No, I have a fairly large electrolyte cap on power supply on the controller PCB, to stabilize the PIR/Wemod/si7021 power source.Actually when the bathroom door is open, and someone walk by the bathroom, the PIR will detect this and switch ON the light. I could consider to update 3D print to add a "wall" to block PIR.
The idea is that this PIR potentially can be used to connect to burglaralarm (but again I need to verify that I dont get false PIR reading due to sunlight)
-
I was asking because quite some people had issues with the PIR being too close to the antenna as the antenna during transmission was inducing some noise that triggered the sensor so they needed to move them apart to solve the issue
-
Depending on the number of simultaneously active relays and the weemos tx power requirements make sure you don't overheat the HLK module, fire hazzard.
My 8 relay board draws a whooping 500ma @5V when all of them are active.
-
@gohan thanks I didn't think of the RF transmission from Wemos should impact PIR sensor, I only have thought of the power ripple. how far distance should affect PIR? I think mine is approx 2 cm apart
-
@executivul
Good point, But I have looked at the power/current budget.
I have 4 pcs relay, JQC-3FF 5V DC, spec: https://www.futurlec.com/Relays/JQC-3FF-05.shtml uses 0,36W each x 4 pcs = total 1,44W.
Usage of Wemos D1 Mini Pro is unknown, at least there is no spec...https://wiki.wemos.cc/products:d1:d1_mini_pro#documentation let says it uses 1 W
HLK01 is rated to provide 3W
Should be all ok
-
@bjacobse I had problems with ~3-4cm. Lots of false triggers on the pir. But if you are not experiencing false triggers your setup is probably fine.
More info: https://forum.mysensors.org/post/78771
-
@mfalkvidd Thanks for the link to the post, I think I should upgrade and use aluminium foil as you done to make a GND shield around the PIR sensor
-
So I have uploaded the 3D design files for my MySensors gateway case to thingiverse for anyone that is interested.
https://www.thingiverse.com/thing:2904969
I have included the OpenSCAD file used to generate the .stl files. I would be interested in seeing posts of other makes or remixes of the design.
-
@dbemowsk Nice work!
Now that I finally own a 3D printer, I can't believe I waited so long to get one. I encourage anyone who doesn't yet have a 3D printer to get one too. Sharing enclosure files in addition to PCB designs is the next level.
-
@neverdie I can only agree - to buy ans use a 3D printer is really good and some fun too
-
@neverdie how are you getting on with setting the printer up? I have been struggling with the correct setting for some time with problems like the plastic would stick to the surface even though it is pre-heated. At the end I got really frustrated and retuned the printer. I am using www.3dhubs.com now if I need to print anything.
-
@alexsh1 What brand/model of printer were you using? Also, what type of plastic were you trying to print with?

It's working like a dream with both PLA and PETG, which are the only plastics I've tried thus far. I'm using the Prusa I3 MK3 (Prusa's 4th generation 3D printer). Following dbemowsk's suggestion, I'm now using Octoprint, running on a Raspi3b, which is mostly useful for uploading print files and monitoring from a distance using a webcam. Honestly, though, once it gets past the first layer, I haven't had any failures, so the webcam probably isn't needed at all.
-
@dbemowsk I was using PLA. The printer was the most popular model on Amazon.
That's the one:
-
@alexsh1 Strange, that looks like a pretty decent printer.
-
@alexsh1 You can buy PEI print beds as an add on for most printers. Maybe that might have helped your issue. When printing PLA, I print a 5mm brim on the first layer, and that keeps the print object from prematurely dislodging later. Haven't needed a brim though when printing PETG, which just naturally bonds very strongly to the PEI print bed.
If there are going to be failures, they'll probably happen in the first layer. Once you get beyond that, it's smooth sailing.
-
@neverdie said in What did you build today (Pictures) ?:

That's exactly what happened. The first layer simply would not stick to the surface. Especially, if it is, say, a larger project box. For small items - no problem.
I must admit I did not spend too much time on this. I tried it for a week and then just returned it. Too much trouble for occasional prints I do.
-
@dbemowsk It is a good printer I suppose. I only used PLA and just did not spent too much time trying to find the right settings. Given that a few prints I ordered were also warped at the first run, I concluded that this is still at the DIY stage.
I'll probably get a printer when technology is going to be more advanced.
-
@alexsh1 NO problem. I realize they are not for everyone.
-
Finally, I can join this discussion!
Today I drew a scheme of my first device! This is a system to protect against water leakage. I also posted it in the "hardware" section. Link.

@neverdie nope, but it is inspired by oriental frames, I just made that based on what I saw on one of my cabinets (which I bought while living in Singapore).

@gertsanders Cool. You might like this pattern also then:
-
@neverdie That's cool. Kind of like an overlapping honeycomb design.
-
@mickecarlsson except I have not yet tested the new things on the back (signing and extra flash) the boards are working. I will try to test the last things before May is over and the publish.
If you want to order I can offcourse email you the Gerber's but on your own risk.
My first experience with the board is that it's performing better than Rev 9 with the new position if the hardware. Also the ground plane helps.
-
@neverdie that is a nice pattern. I found that these things need time to draw. If anyone has a DXF file, I would love to try it.

@sundberg84 thanks for the offer, I can wait for the final, no worries. Do you have a list of the new components added on the back?
