@ykhokhlov would like to get it going as well, have a requirement for a tiny form factor, have had one of these in the drawer forever.

How are people getting on with these boards, mine just arrived today so doing a bit of testing. I wanted one as a replacement gateway for home assistant. I've got it working at 1mb and the pin changes suggested above, just wondered how they worked out for people in practice over the long term.

I also wanted to mention that there is another option although it would work out more expensive

If anyone in the UK is after boards/parts i have spares.

@Mark-Swift

Well i got myself a Worx Landroid 794E from ebay, just looking for a base station and boundary wire now and i'll be up and running. Did you ever sort your issue to stop it going out in the rain?

@Ashley-Savage Had a big rewrite this evening and all seems good now. If you set it to a level then switch it off the level is remembered so if you issue an on command it goes to the previous level. It seems a little bit more stable as well but i'll not know fully until i put it outside for use in the wild as it where. I'm thinking i might change the DHT11 for a Dallas sensor though as i received a few waterproof ones this week as they should be more accurate and can support negative temps which living in the UK i'll need come the autumn.

@Ashley-Savage No worries, btw i made a couple of changes last time which i never mentioned. I've made it so that if the PIR is tripped it sets the fade to 0 so that if Domoticz then sets the light to on it won't gradually fade up and will come on straight away which is more the behaviour you'd want from a security light. After 10 seconds however it resets the fade back to 50 which gives a 5 second delay which means that when domoticz turns the light off after 1 minute it'll nicely fade down. It also means if your manually controlling the light it'll fade on and off nice and smoothly.

I've also just made a change today as i was lurking on the forums and read a post about pwm being flickery intermittently which i've experienced personally and it was down to TX/RX and ERR led's being set to use PIN 5 which conflicts with what were using the pin for sometimes causing flickering. It now seems to work nice and smooth every time.

I've only just a few remaining issues in that if i turn the light on rather than asking for a percentage it goes to 100% which i can see the logic to but what i'd ideally like to do is have it turn on at sunset at say %15 then turn to %100 if it's tripped then go back to %15 but it returns it to %100 because of the above%100 at one command i think, might have to put it in the blocky script but it'll be difficult as i also like it to turn off at 11pm and only come on if tripped so just used as a security light. Last issue is it refuses to respond to on/off command sometimes but you can bring it back to life by using the dimmer slider to gradually power it off then it'll respond to on/off commands again which is weird.

I think i might try the default sketch again for just the dimmer to see if i get the above behavior.

You my friend are a genius, i was having flickering on my dimmer and couldn't get to the bottom of it. I was using pin 6 for controlling my LED strip.

@gregl said:

I was having some probs with the led dimmer sketch the other night beacuse i wanted to use PIN6 rather than PIN3.
My LED strip would flicker....had me puzzled for a bit until i remembered the mysensors v2 beta ( im using quite an old cut of it ) uses pin 6 for the RX/TX/ERR leds...
So i just reassiged them in my sketch...and problem solved!
#define MY_DEFAULT_TX_LED_PIN A2
#define MY_DEFAULT_RX_LED_PIN A3
#define MY_DEFAULT_ERR_LED_PIN A4

This may not be relevant to your posts... but i thought it was a PWM frequency issue initially!

@Ashley-Savage 0_1464007588143_security light.fzz

Not the easiest thing to fritz as it looks really messy.

Also i've found the design done by a guy called quindor which uses an esp8266 is working much more reliably for me with regards to dimming etc. He's got a great write up on using it with domoticz. I have two on my garage and also in my kitchen as accent lighting. Blog

I'm running a sketch based on the dimmer example on a pro-mini 5v. It works ok except that when switching on and off it ignores the set percentage and jumps to 100%. This also happens when using a blocky script. I wanted to have the light set at 25% after sunset but then when motion is detected from the motion sensor to set the light level to 100% for 1 min and then return to the previous light level. If i have the light off it returns to zero ok but would prefer it to run at 25% level after sunset.

Anyone had any similar experiences?

Updated the sketch again and have updated the first post to reflect the changes. I realised after i'd re-assembled everything that by putting the delay in to stop the PIR sensor spamming the controller that i was actually stopping the controller turning on the light for a full 10 seconds which resulted in a rather rubbish security light lol I've now modified the code so that a second variable is used in conjuction with the PIR status itself, a timer is then used for 10 seconds so that it will only send one update that it's been tripped. After 10 seconds it's able to be tripped again. I'm still using domoticz to control the logic of turning the light on but having a few issues so i'll post in the domoticz forum for help.

@NeverDie Thanks i'd took the 1 led off but have taken d13 and the regulator off now. Sitting at around 2.7v although as i'm more so testing i'm reporting the temp as often as every 5mins if it changes.

@kenci Hi Kenci, yeah i'd been in contact with him through ebay as i purchased it from him but sadly he wasn't able to assist too much as he said he was a hardware rather than software guy. I figured it out in the end, wasn't rocket science and just took a little digging which i'm not adverse too but just couldn't see it at first.

If anyone is thinking of using this board Cory produced a PDF which has build instructions for 3.3 and 5v, I've uploaded it so it's easy for people to find.

0_1463498990546_MySensor Pro Mini V2 - Google Docs.pdf

In case anyone is interested this is what the assembled board looks like on mine minus any case. You could get it a lot thinner if you skipped the connectors and soldered directly but i've an aversion to that as i keep tinkering.

@mfalkvidd @MikeF I've now resolved the issue. With this board you have to set D3 high so that it powers the radio, shame as that really ties pin 3 up then but i guess he's done it to make the radio optional as he supports bluetooth as well. It's a nice lower power board but i think i've been spoilt by the otherboards i've used which have used the same pinouts etc. I think the solar one which you have may have been of more use thinking about it but hey ho. It's trivial but just incase anyone else is as simple minded as me i put the following in setup

pinMode(3, OUTPUT);
digitalWrite(3,HIGH);

Thanks
Col

@MikeF Hi Mike, thanks for the response. Yeah i'm on 1.5. I've just removed the libraries just incase and reinstalled and uploaded the serial gateway as well as the sensor itself for completeness. Still getting radio init fail

Hi Guys,
Has anyone bought one of these boards? I've modified my code so that it works with pin 7 and 8 as he's these rather than the regular radio attachment pins. I'm just getting Radio Init Failed messages, any advice?

MyTransportNRF24 transport(7, 8); // Ceech board, 3.3v (7,8)
MySensor gw(transport);  

I've tried external power as well as battery power with the same results.

Universal board

What size SMD did you use for yours? I might see if i can get a variety pack myself from amazon, i'm in the uk so have access to amazon. I think one of the resistors is 470r rather than 470k so the voltage divider didn't work although as i'm feeding it with 3v from two AA i used the internal reference method which worked well. I have to say i thought it ended up being quite long too and then when paired with the sensors you end up with some funny shapes to try and fit in a box

Col

I've just actually got around to soldering mine together today after having the pcb's sitting there for months. I had ordered a load of capacitors and resistors but rather naively didn't realise that there were different sizes for smd components, silly looking back now but just didn't realise. My soldering skills have improved slightly though so had another go and managed to assemble it today. Biggest problem was remembering what smd components were which as the ebay sellers never label them well.

Have you ordered some already?

@TheoL I tested everything again tonight and did some troubleshooting using the default motion sketch which worked. What i ascertained is that my sketch was setting the motion sensor active but then never sending a signal to say that the sensor was no longer active. I'll be honest that i couldn't see the default sketch doing this either(unless it does this via an interrupt when it goes from active to inactive) but i modified my program so that it now sends a notification that the sensor is no longer tripped which solved that issue. I also put a 10 second delay in as the lowest setting i could set on the sensor was 5 seconds or so which meant my sketch spammed domoticz that it was tripped. With the delay it sends a message to domoticz once now, waits 10 seconds and then sends that it's no longer tripped. With this I've been able to enable the domoticz control so that it will turn the relevant light on for 1 min at %75 if motion is detected.

The only issue i've ran into is if i've already got the light set to say %20 which i like to do after sunset then when the light gets enabled for 1 min domoticz doesn't seen to turn it off.

@koen01 I spent some time after work and updated the code so i've updated the first post with the code in. It now works for the PIR part.

@koen01 when the timer is running the main loop is still running so it's able to respond to dimming requests. I have implemented the PIR alerting poorly though so need some kind of delay as when the PIR is activated it spams domoticz for half a second so I'd rather is delayed so it's not tripping it so much. I'm traveling at the moment but plan to change it when I'm back at the end of the week so will publish the changed codes.

@Mark-Swift I was looking at the Worx Landroid as it seemed pretty good value.

Small world lol OSG is a nearly distant memory now, disbanded in the UK a few years ago nearly now, remember seeing you'd got the robot mower and when i saw your name i put 2 and 2 together and got the right number for a change lol. Been tinkering with the mysensors stuff and Domoticz lately. Only got a few sensors going so far but working well. Not to go too far off topic which mower did you go for BTW been looking at them myself.

@Mark-Swift Random one here, you didn't happen to work for a company called ABS in the past did you?

Yeah was working great and was good for a day or so. I wonder if i've shorted the sensor or similar somehow. Shall have to bring it in doors till i can troubleshoot it. Think i'll have to look at OTA programming as once you get them in enclosures such as this it's a pain lol Thanks for the feedback. I've ordered some more PIR senors too so if i can't get to the bottom of it with the one i have i can always try another.

Hi i got spammed again but this time the alerts never stopped. I forgot to mention that when i was testing on the device and had it in the house i had the serial port hooked up and i put in some extra comments so that when it was sending the sensor status it was only doing it when it was tripped but the wierd thing was domoticz was still showing tripped but the sensor wasn't sending anything if that makes sense.

Has anyone experienced any issues with PIR's in the latest beta. I upgraded earlier this week to the latest beta and now my PIR sensor i built for the garage activates ok but then does not seem to revert to a non activated state even though it's not receiving any notifications to say it's been tripped. I've included a sample of my log output, even though the last trip of the sensor was at 10:02:09.905 in Domoticz it still shows as activated. Is this just something wierd with my setup?

I've mashed together a few sketches to create a kind of security light. I've not put any logic for when the light should come on in the sketch and instead let my Domoticz controller decide when and what intensity the light should come on. In this way i have it set to a very low level of around %15 from 30minutes after sunset till around 11 but if motion is detected i bump it up to %75 for 1 minute. I've done it this way as i can control it remotely and also modify the delay/intensity etc without having to open up the case. I'm also sensing the battery voltage of a 12v battery. I'm using a 1M and 470k resistor although i had to play with the resistor values, the 470k one in particular in the code to get it to be accurate. I am sending the temp every 2 mins and the battery voltage every 5 mins using a timer and the main loop monitors the motion sensor and sends that it's been triggered otherwise it just loops around again. I had looked at interrupts and sleeping inbetwen but then i couldn't see a way to control it remotely as Domoticz wouldn't know when it was awake. It seems to be working ok for me so hope it helps some people.

I housed it all in a small project box which is secured to the underside of my garage and the light then connects directly to the circuit. If anyone is interested in a fritzing diagram then please let me know.

Rude to reply to your own posts or so i'm told but for the benefit of others i was being an idiot and pin 4 isn't pwm (facepalm) i was looking at this for a while last night as well. Ah well never mind it's working brilliantly now after switching to pin 5

Hi guys, i'm trying to put together a dimmer circuit as well as a temp/voltage sensing and motion as well. I've got it all hooked up bar the motion side of things and the temp works great, voltage is sort of ok although not that accurate but can live with it but the dimmer side of things doesn't work great. I have used a STP16NF06L rather than the IRLZ44N but i thought this should be ok since i've used this in a ESP8266 dimmer project along with mysensors and Domoticz and it works great.

What is happening is it's not actually dimming, if i put it above %50 it turns on but then it's a constant brightness and doesn't get brighter or dim going the other way. Is it just down to the mosfet substitution? I've tried with the standard sketch and it does this. My modified code is below. Any help would be much appreciated.

@GertSanders Thanks for the heads up. I'd incorrectly assumed that it was going to be something like $10 plus shipping. At $2.20 it's nothing so ordered a few just for testing. Got carried away though and ordered a few 8266 breakout boards too

Col

@rmtucker I was thinking the same, don't need a whole batch. Anyone got a spare board, happy to pop some cash your way via a paypal gift.

I have one of these lights and got it with the plan of dissembling it for this very project but it was too good lol so think I'll buy another to dissect. The only disappointing thing is how the light is always on at a dim level so drains the battery. I'd much rather have it only activate on motion detection with the PIR.

@Cory What size SMD components are used for the caps and resistors?

Just ordered 9 boards to test with and ordered a lot of SMD components but then realised they do them in different sizes, SMD is very new to me. Most of what i've ordered are 603.

Great looking boards from OSH Park, seem great quality.

@Cliff-Karlsson I've been looking at these too, really like the editor idea.

Spotted this review/info
http://tronixstuff.com/2015/05/23/review-nextion-tft-human-machine-interface/

I was looking at the 3.2" Model which seemed the sweet spot price wise, seems to double in price when you go upto the 4.3"

@LastSamurai you need to paste in the test after the link onto the end of the url. Else search for "Scullcom Hobby Electronics #14 - GPS System with Arduino Mini & OLED Display" in youtube.

@LastSamurai http://www.ebay.co.uk/itm/215-Router-Shell-Network-Communication-Plastic-Project-Case-Box-160x100x30mm-/171579990253?_trksid=p2141725.m3641.l6368

@NeverDie For some reason it keeps auto converting the link but as you pointed out it doesn't then work! I've put a space in so you can see the url, you'll need to copy and paste but then remove the space. If anyone knows why it won't work when linked normally i'd love to know

I stumbled on a youtube video where he used a project box with a pcb designed for the box which i thought could be pretty handy

http://www.ebay.co.uk/itm/ABS-Project-Box-Cases-Lids-Matrix-Boards-5pk-300651-/121366415075?hash=item1c420086e3

Anyone tried these?

Edit: This was the youtube vid https://www.youtube.com/ watch?v=e1y4IG6YSoc&list=WL&index=16

Oh and does anyone know a source for the box shown above in the UK or someone that ships to the UK for reasonable costs. i looked on ebay but couldn't see any.
