Luckily it works great since my controller (fhem) not yet support EthGw v1.5.

Great that you found a solution, thanks for reporting back!

Hi @n3ro. You have written the correct command. You dont need the incomingMessage if the sensor doesnt expect that. Yes, atleast the nodes in strategic locations. I have some node in the outskirt of my network which is USB powered and not a repeater... no point how i see it. Dont use delay() or block code in any other way if you are using it as a repeater.

Welcome to the MySensors forum @JagWalia ! The getting started guide explains how to get started step by step

Not sure if implemented but pidome was talking about it in a video,https://youtu.be/ROlXtpefjqM

Thank for your informations, I dont need sensor on gateway, so i keep my gateway on Arduino Mini pro, it's more small than Mega. Thank again.

I have now decided to stay at TmrH20 - Basis... that is working fine for me... Thanks to all, trying to help.

Hi @Rolo6442u - welcome! st=fail means the radiotraffic between the node and gateway fails in some way. Sometimes it can reach the gw, but some more skilled in the code need to present you with the details. If you use a nrf radio and you dont use a 4.7uF cap on VCC-GND thats a good advice.

Hi! You should try to make a node with the TCRT5000 IR Barrier Line Track sensor It emits an infrared light and detects the reflection. Its used in the water meter: http://www.mysensors.org/build/pulse_water http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575069610&toolid=10001&campid=5337433187&customid=&icep_item=330924700585&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg

Looks good.. I found some code here for it: http://forum.arduino.cc/index.php?topic=212749.15 I've not looked any further as to what people may have done with respect to counting people etc..but im sure there is some out there! Not too cheap though.. $80AUD here!

Thanks 4 all the input! I thought about measuring only, but powering the node is a possibility i nearly ignores. Stupid me ☺ This intercom has a regulated 18v DC power source. So i should be fine.

@riataman has a solution here that might be useful.

I don't think Arduino has a standard sleep function. Which function do you mean? The MySensors sleep function does several things, including powering down the radio (if a radion is used). It is quite power efficient.

THanks for the replies... nah, i suspected it wasnt the best choise since all I could find on www wasn pretty much on raspberry client / speaker.

Yes it will work. You can also buy from ebay or Aliexpress. links are available here if you scroll down a little bit.

@gandy-bruno I think that the next release will be 2.0.0.. (Or that is what we are aiming for at the moment)

:+1: signing seems to be fine ;) thanks 4 info

The greatest thing about mysensors is, that it can be combined with almost any home-automation controller. That was the reason for me to have a closer look at it. I will be able to reuse my whole sensor network when I will exchange my controller in future. Riot would be interesting for me if the hardware is cheap and if there would be a nice housing for the babies, and ofcourse if it would be compatible to mysensors.

... and to give the DHT sensor a chance on reading errors to retry and not to wait until next cycle which might be very long: for (unsigned int i = 0; i < DHT_MAX_TRIES; i ++) { float temperature = dht.getTemperature(); if (isnan(temperature)) { Serial.println("Failed reading temperature from DHT"); gw.wait(dht.getMinimumSamplingPeriod()); } else if (temperature != lastTemp) { lastTemp = temperature; if (!metric) { temperature = dht.toFahrenheit(temperature); } gw.send(msgTemp.set(temperature, 1)); Serial.print("T: "); Serial.println(temperature); break; } } Repeat the same for humidity of cause.
