For the best use of the project you have been looking at, and if you are considering building a controller, surely the vera is the right choice.
There are some limitations with other controllers, but if you read that topic you know that issues already 
Hi @dbemowsk , Thanks for your reply. I had to reinstall Arduino IDE and all Libraries from my PC. I was fighting with ā'POSITIVE' was not declared in this scopeā error, and installed over 6 Libraries for LCD. I got finally working the sketch for Vera from Mysensors/build, at least .
Unfortunately Iām not able to modify Sketch witch are guys using with Domoticz in this Topic.
Is there a way to get missing variables into Irrigation controller from domoticz or at least to set them manually in sketch? For me is enough one watering time for all valves.
Hi guys, Iām trying 2 days to compile this sketch for Domoticz. Still getting errors ones from library then from code...
Can someone share with me his working code for Domoticz in 2.0 version? Thanks a lot
I had same problem (but on serial GW). It started after I removed IRQ connector. I was able to add devices (using Domoticz as controller) , bust after few hours it stops to work.
Im on Domoticz since 2015. Running with Mysensors, Rflink(433MHz sensors), HA-Bridge (Amazon Echo), Broadlink (IR, 433MHz). Iwas looking at HA months ago - UI looks better, but then I installed Dashticz and my only problem was solved
No debounce function in sketch. Im just looking for some examples. Is the best (only) way to do it trough debounce.h library?
Thanks gohan
Hi Guys,
I have a MS gas meter based on Water meter sketch measuring on BK-G4T gas meter. I am using Mader reed switch. During winter my readings were corresponding with analog scale on gas meter (I had 6-12m3/day - heating, Hot water and cooking). But now in summer (Cooking, hot water) I am getting 0,5 - 4m3/day but real consumption is only ca.0,3-0,5 m3 a day. Has anyone idea how to correct this or what causes the problem ? Is the magnet (on analog gas meter scale) stuck in some position causing it?
Thanks
Hi Guys,
Is there any way to integrate difference pressure sensor MPX2010DP into mysensors? Did somebody played already with this sensor?
Or is there some better way - sensor to measure filter pollution in ventilation system, integrable into mysensors ?
+1 for RFM(433Mhz)
IĀ“m already running NRF and keeping it (have build many nodes on it). But, for example I have a garage (steel structure with sheet-metal paneling) and its ca.6 meters from NRF gateway - no signal! Same distance RFlink (433Mhz) works just fine.
Most of these cheap sensors are based on PT2622 chip or similar. RF link works fine with them.
Thanks Guys!
I have edit the sketch and modified the sensor. Records made during night are finally closer to real situation. I need to correct pulse count.
@karlheinz2000 - are you using digital or analog output as on FHEM forum? (Danke, fuer Deine Anweisung)
Yes IĀ“m using example sketch. So my interval could be up to the fastest theoretical revolution ?
Hi Guys,
Does somebody have working pulse meter with TCRT5000 on analog power meter (Aluminum rotating wheel). IĀ“m fighting with it right now and I need some help. Do I need to modify the sketch? IĀ“ve adjusted pulse count according to power meter specs. The sensor is on all the time (while white / Al part of wheel) and turns off during the black part of wheel. During on time sends the sensor loooot of impulses, so I had my consumption up to 300 kWh a day and usage up to 100kW. Had someone same issue? Thanks a lot
Exactly, different GWs, different Frequency and protocols.
I've gone same route as you are starting. After all I'm at Domoticz + MS gateway + RFlink. Works beautifully.
Hi, check domoticz forum, there are some infos too.
IĀ“v done this for my friend while ago, only he had motorized screen already installed. But building screen is no problem as well. Use some tube motor - has build in end stops, and they are easy to adjust.
Automation part depends on your projector - if you have trigger or no (newer does). You can use trigger signal to control screen without arduino trough relay. Check trigger current and better divide both circuits.
More complex, but more fun is to use arduino + relay board. I did it this way, and added control of cabinet door (in which is projector located ). Arduino is also controlling temperature of Projector, and protect it from overheating in cabinet.

NRF conected to arduino
I have seen some installation tutorial in Domoticz wiki, for sure on Synology, not sure if on Qnap - check that.
I had same problem with mega (clone) - tried to program relay and temp node on mega - all over "check wire", and when i switched to uno did compile.
Halo @Stuntteam ,
I red all from nemcon site, and couldn't wait to start with it. I do have a Mega at home and I do have plenty of RX/TX lying around. Unfortunately its cheap Chinese stuff and I spent few hours trying to receive some working signal 
Today I ordered exactly same RX as mentioned in nodo e shop. I'm really excited, you did great job.
Question: I was looking on PCB in eshop, and I was wondering about the NRF (you just explained it ), and i saw just receiver - no transmitter. I'm I right, or is it there?
Thanks for your work guys!!!
First of all choose if you want to go wire or wireless.
But even by wireless (433, 868, z-wave, enocean, zigbee, 2,4Ghz...) you might need power lines for motors, actuators, pumps, blinds...
First of all write down what all you want to control, and based on this list try find the best system. I would go with wired system on beginning, and add wireless stuff for unreachable or outside controlled parts.
Hi, Dutch guys, does somebody have experience with this?

Is something wrong with identification of relay? Temperatures are working just fine.
Hi Guys,
So after few day IĀ“m back again

It compiles, temperatures are working but relay is not working, can someone help me, pls.
@sundberg84 next day after I switch to latest Domoticz beta system started to freeze again. IĀ“ts only after relay switch command pushed by user or even by timer (when I checked the logs of the switch all times are loged 5-7 minutes later than the switch time). Is there any tutorial or does exist system how to switch my Domoticz to your version (2606), without installing all Domoticz manually? I was able to run SD versions only and 2606 is zip file.
Thanks for your time Guys
Thanks @robosensor , IĀ“ll try it.
@Moshe Livne, Sure they can - on coil (at least mine is built so), but board must have jumpers to separate it . Input must be 5V- of course transistor would burn. I'll try your suggestions, thanks
Exactly - I tried other sketch yesterday, that worked same way - LED turned on, but contacts stayed off. I will try to power the relay board separately with raw voltage from Arduino (9V)
When IĀ“m uploading sketch both two relays start to light and during upload switch off and when uploaded turn on.
Hi sundberg84 , Thanks for your advice. I was only able to upgrade to beta 2650 (my programing skills are very poor ā I followed steps in Domoticz wiki). Domoticz environment is working OK now, I can switch and icons are changing properly. Relays are still death. I replaced definition of 1/0 for relay write in arduino code so relay LED begun light. In serial monitor of node I can nicely see āincoming change for sensorā and ānew statusā by every command from domoticz for each relay, but there is no switching at all.
Hi Everybody,
First of all Thanks to all of you people and Mysensor Team for creating this and sharing it to all of us.
Iām one of āninjasphereā backers, and after this project crashed, I started searching some DIY possibilities and I found this. Iām running Domoticz (ver.2563) in RPi2 and serial nano GW (on 1.4 code and libraries). I successfully created Temp/Hum and multiple Temp sensors but I got stuck on Temp/Relay node. Temperatures are working just fine (5pcs. DS 18B20) but the Relay wonāt work. Temp sensors are on Pin3, Relays on 5 and 6. Iām using sketch I found here on forum:
// Example sketch showing how to send in OneWire temperature readings
// Example sketch showing how to control physical relays.
// This example will remember relay state even after power failure.

When I push switch in Domoticz it just freeze up, and I have to unplug RPI and restart it. Do I need some special adjustment in Domoticz for button?
Does anybody have working relay/temp sketch on Domoticz, or can anybody give me some advice?
Thanks guys
