Do some debug on the node and on gateway and check if data is actually sent from the node and received by gateway. Also use wait instead of sleep if you are using it as a repeater and relay actuator.

BTW, I like how you both made a case for it. Very nice!

I liked domoticz (was very easy to set up and use). Together with dzVents scripting wasn't that difficult either. But I also had some problem with it lately, so I was actually thinking about switching to openhab (2).

Just to let you know, that best result I got was when I changed the DHT library (sparkfun) for the one with this sketch. with this sketch. Thank toy for your time. PH

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

I think the comment in the routine void measureBattery() { // R1 = 1MOhm, R2 = 220 kOhm Should be void measureBattery() { // R3 = 1MOhm, R2 = 220 kOhm (R3) Is it possible to add (comment out) some lines how to calculate the battery percentage and send this via gw.sendBatteryLevel (batteryPcnt) Great sketch!

I've a sensor running with naked 328p, 3.3V, 8 MHz internal Osz and DHT22. Maybe I'm lucky?!

Yes i made several reset, exclusions, inclusions, vera reset and clear EPROM but nothing worked... I made a new sensor and it works perfectly Strange... I will try again when i will have more time. Thanks for the help

@AWI I 'm doing a similar project prodias help me make connections as your project and how to perform with I2C
