Well its been a bit of time and my home automation system with Domoticz is great !!
with the great guys here allowing us to make sensors that would cost a lot more if it were a commercial product ,,Thank you all again to all the great work.here .
Right lets get on ,well I have been testing these reflectance sensors ,they are only approx 3 pound each on Ebay .I have combined them with a multi-sensor sketch ,I have given a link to the item below plus a screen shot of my floor-plan with in Domoticz .I am thinking along the lines of one inside the door and some in the hallway then when you move say from front room to kitchen it would trigger sensors front-room hallway then kitchen ,hmmm .that coupled with some PIR sensors might do the trick,they have a range about 36 inches ,so pop the by the door or in the ceiling (ceiling for me) .very easy to setup they run off 5volts I use pro mini 3.3 volt
link to sensor I am sure you have seen them out there

Yes could you please confirm how the nano is connected to the sensors ,soil sensors please ,yes 5+ 0- pin 3 ?? or in your sketch pin 6 7 ? to were
or a0 a1 please how?? pin 6 to pin 3 on nano ?? it just not clear ??

I hope this is in the right Place , please feel free to a move to better topic if needed.
First things first I would like to say a BIG thank you for this great site and ,Bruce Lacey,Henrik Ekblad,Olivier ,Mauti,Thomas Bowman Mørch,Pete Will,Patrick Fallberg and all other contributors .I am converted .
I have Domoticz with quite a few sensors .
I Promise once I am bit more solvent ,I will donate ,(at present no job).
I’ll get to the point maybe some ones already investigated this ,but here we go
wall lights a relays .Well relays can take up a bit of space ,well this seems like good alternate ,
With Zero voltage switching .
Measuring 1 cm square ,interested ??
Manufacturer: SHARP

Manufacturer Part No PR39MF51YIPF

Made by Sharp 39MF22 7 pin package <<Google it
Well there did seems to be a bit of problem over here in the UK since ordering one would incur a £12 postage some company had a fixed postage for any order, making it silly to order unless you were ordering a crate .
I did some googleing and found Farnell components a much better bet .
I have tried tested 39MF22 with the relay Sketch, I did not add a snubber circuit ,but for me it works well.
I was using X10 equipment before ,soon I will be changing all wall switch’s to Micro Nano plus a 39MF22 etc. with the

limited available space ,it looks like I will be able gut the old X10 switch’s and replace with new electronics .
There may be a issue with RF interference with component’s being in close proximity But as for me this works well with

Zero voltage switching a nice touch .
If you push me kick me,, I might put up some pictures of the converted X10 wall switch ,won’t be too pretty but might give

you some ideas .
Oh it seems to work fine with florescent lighting (tested) .
The 39MF22 can handle 900mA and has an isolation voltage of 4kV
Max Power just under 200 watt ,I believe

Thought I would throw this in the pot
Why not change the sensor Probe ?? no credit to me , just was googleing as you do,
Home made sensors I think less prone to corrosion
here's the link

Had some seeds from very tasty tomatoes last year ,have planted and this year growing like tiffids !!
Getting quite big so have move from kitchen to Greenhouse ASP really
Will try with this type of sensor

Two projects I am looking at present ..I take No credit for any of this work, it is other peoples project out there on the internet ,but I must say Quite interesting ,,so here we go
Amazon dot (echo as well)
I thought it would be worth mentioning here, since it works quite well with Domotciz and mysensor units ,and you other guys might like to try it.
Check out this URL
http://www.makermusings.com/2015/07/18/virtual-wemo-code-for-amazon-echo/
I have run the python script on the raspberry PI 2 and adjusted the Json script to switch lights of and on ,works well (Up to 16 units)
Arduino-controlled-battery-charger
This project by some one out there is about the only standard charger for non lipo Batteries I have found
( I am sure other people will now mention others,, please do)
here is the URL
http://www.allaboutcircuits.com/projects/create-an-arduino-controlled-battery-charger/
you can monitor the serial out to see how well it is charging
I thought about adding this WiFi to Serial Bridge, Arduino, RPi, ByPic
ebay item number 311554685109
It would really nice ,if some one could add a LCD to the sketch +++ some buttons so the charge could be adjusted OR it could made in to mysensor for Domoticz
Some one has tried to duplicate the charging circuit for 4 batteries ,but the developer has said there would not be enough inputs for the temperature sensing of 4 batteries

Oh and Merry Christmas everybody ,Happy new year have a mince pie on me .

And here's the completed unit I have not really tested the range yet ,
but should be good , the receiver units (telemetry units) can work in latching mode and in push button mode easy
I am pretty sure this setup will last longer than fibrio key fob , easy to pair receiver with key fob
I have 3 key fobs ,, yes why ??? well they will break and I rather purchase few ,for an investment for the future

Maybe some can help me with other project the stamp m5 pico trying to program it is a standard switch node
