ive got openhab and gateway so shouldn't be a problem with hass 0_1577584196725_IMG_20191226_024628.jpg

interesting just bought some sonoff no neutral light switches needs a cap across the live / neutral is rgis the same ?

thanks

I've ordered some 3.3V version Arduino Pro Minis and will try again

I knocked up some door sensors with a nano and a 2300mAh 18650 using the sketch in the demo page

problem is Im only getting about 3 days battery life have verified the capacity of the batteries in my opus and the batteries are good

Ive always used mains power on a usb for my temp sensors this is my first attempt at a battery one

would I be better using a different arduino I was hoping for it to last months not days

any help would be good

apart from the size can anyone see a disadvantage of using 18650s

I have over 300 of them I got for free done a quick test the holder ive got from AliExpress have 5 and 3 V output out the box

thanks all the design has changed I plan to heat some medium and have the water pass though a head exchanger what way standing water will never be consumed later

there is a commercial product called sunamp which is designed for this purpose

@zboblamont

its solar electric I have not thermal
this will explain what I'm trying to achieve

http://www.yougen.co.uk/blog-entry/2522/How+to+benefit+from+solar+hot+water+with+a+combi+boiler/

Ok bit of background I have solar at home and have built a power wall . Still have excess 9 months of the year so want to heat some water for free, only snag have a combi boiler

Discovered mine will accept main water temp upto 60 Deg so thinking add a hot water tank before the boiler use less gas.

Only problem I want to ensure that the temp in the tank reaches 60 Deg at least 30 mins each day to limit bacteria

My solar system has mqtt do turning the heater on and off shouldn't be to hard.

Any recommendations for measuring the water temp ?

guess no odb port?

id also second the use of 18650s

Know officially the nano needs 5v
Has anyone played with the minimum voltage you can get away with

Wondering if I can run them off one 18650 ?

If not will use 2 plus a 7805

I'm still planning my set up but wondering if anyone was using magic mirror to display their sensors ?

Thanks Arden

Thanks I found the old posts will look for another use for them

Original plan was waking up esp8266s

Mainly because I have some bought on a whim has anyone used these before in a sensor project ?

need to do it with a few live sensors then will be happy

but going to call that a win for today

thanks for the swift replay

Ive sorted it

put it next to the pi and it worked then realised I had not put a cap in the PI's radio did that and its now working fine

only had 10 micro_F but seems to be working ok

hi all should the nodes pair with the gateway idiomatically ?

I have a new gateway running on pi and from what I can tell sees the radio on

have loaded mock sensors code on a nano and get the following output on the tty window

not sure how I see what the pi os doing its on Doniticz cant see any sensors in there but can see the gw added

am I missing something?

thanks

Arden

I had some time and made the gateway on a raspberry pi in the end
is there any reason you cant have the gateway on the same pi as the controller ?
also wondering if Domoticz is a better option for this then hass

Im not very invested in hass right now so easy to switch

thank you out of interest does each sensor need its own controller or can you have a room uno which all the sensors in that room go to
ask as I have 3 unused unos and a mega

First I cant believe I not found this place before have a couple if esp8266 sensors powered on mains transformers wasn't until I looked to battery power I found you

couple of simple questions I plan to use an orange pi pc mainly because its been sitting on the shelf for about 2 years unused is there any problems or should I use a raspberry one

I also have 100s and I mean 100s of 18650s left over from a DIY powerwall project anyone else use these seen lots using the coin type batteries

just set up HASS on a pi will this talk to the controller out of the box or is there an addon or config required

basic questions just trying to get my head round my plans I,m in and out of hospital at the moment need something to keep my mind occupied
