"Moteino is just one of several brands of low power Arduino"
By using a pro mini and following the advice of removing both the LEDs and the power regulator using standard radio and a door contact sensor or something could you still expect 2xAA too power the device for a year?
Or do you need to move too a board like you recommended too achieve that length
"Moteino etc.."
Thanks for the recommendation i will have look into this i have not heard of them yet and might save the work as you said
"two AA batteries on my gas meter node last between one and two years"
I would be happy with anything anywhere near too that
" First lesson may be to ditch the DHT22"
Why would you recommend this i have read there are better alternatives (lower power & faster refreshing)
@zboblamont i will get my hands on some pro minis and give it another try i did get it too work with a nano now im trying too combine my temp dht22 with a door sensor but also want too power a different door node from battery so will move too the lower powered pro mini as you recommend thanks for that
Combining sketch / adding multiple sensors is what i need too learn now
Hi @terence-faul did you fix this?
i'm also trying too merge a door & dht sketch but have not got a clue where too start
if you have solved this can you post the working sketch
Ok sounds good too me I will order the parts and give it a try
reading the doc on how too build it says use a pro mini will i be ok using a nano? can you use any board with any sketch?
i think i will try too wire two sensors too independent pins it sounds simple enought
Hi everyone simple question here
When building a door sensor using the door /push button sketch does it matter if you use a NO or NC switch or is either ok?
Also im thinking if you wire two NC door switches together you can detect if two doors next too each other have been opened am i right on this?
I have solved this now.
I was using a NRF24L01+PA+LNA for my gateway radio swapping this for the same radio used on my sensor the NRF24L01 2.4GHZ everything started working straight away.
i was hoping to use the bigger radio for better range any ideas why it didn't work
Hi and thanks for a reply
Yes i used the mysensor binding in openhab i was going too try mqtt but thought best leave learning that for another day
I think the gateway is working its connected too my network and online, pingable and openhab does say it can connect too it.
as for the node ID, no I have not manually set it in the sketch as i don't know how too do this but i did need too do something node related in openhab im not sure if this was the needed thing openhab asked me for it
at the moment i just haven't got a clue what stuff looks like when its working an not
Sensor Sketch was example on the Humidity Page

* The sensors forms a self healing radio network with optional repeaters. Each

* network topology allowing messages to be routed to nodes.

I''m already running OpenHAB have been for some time so that's my controller
but i'm new to Aruino and my sensors, I have got the parts needed to build my Ethernet gateway and my first sensor (DHT22) i have been battling beginner problems all day but i'm not sure if anything is actually working and don't realy know where to go from here
also on the sensor itself should i see the temp/humidity readout on the serial console i only see errors i dont understand at the moment
here's a readout from the serial console of the sensor
