this is the recycled tipping bucket rain gauge i found at the bottom of my garden
this is my sensor node .. fake uno bnp180 dht11 with a nrf radio .. all running an upcycled laptop batterys at 8volts 2c balenced lipos (home made)
heat shrinked sensors with plenty of air flow and venting with nrf radio
orignal radio and mcu for the rain gauge
some of todays data
see it did happen ...
lol

change the code a little bit and bingo you just made a light thermin .. cool for wearables 
ok.
ill put a serial interface on to it and keep it running for debug data ..ill post up the next 3 hours of data later on this evening ..
to me it was very easy to hook up and get working ..well done Yveaux you have given my collection of esp's a new life when my phone recharges ill take a pic and upload it ..i like the way it reboots when connection is lost .. handy feature
well done kudos to you
ok i have used a esp8266mod dev board for my test hooked it up flashed the sketch and domoticz is seeing it ok and relaying my sensor data .. not a painfull process at all ..
will update tomorrow to see if it fails or goes fubar ..but so far so good :P)
i have a few esp8266mod demo bords a node mcu 9.5 a few esp-01, when i get home i will throw a gateway together and test all you like ..i do not mind doing alpha or beta testing if needed ..great work btw ...
also has anyone used this beta .. looks very cool aswell http://www.esp8266.com/viewtopic.php?f=29&t=4540
kind regards
andy
hahaha love it
how about some gas sensors to measure co2 and methane and sulpher dioxide 
ultrasonic to measure speed of turd under gravity or pressure 
i use 2cell 7.4 volt recycled laptop battery packs for my projects thay have a natural discharge of 5% a month but do some reading and research on how to handle and charge them...and you should be fine..plus recycleing lappy batterys is good for the enviroment..and you also learn about the new breed of batterys and cells
cheers for that sparkman ... i was thinking of trying some sort of 433mhz sniffer to wifi serial setup..and hook up a 70cm coliner antenna to the radio with a bit of filtering and narrow the band down and see what is out there that can be used in a local (mesh) of sensors.. i turned my 70cm ham radio and tuned it down to 433.92 and there is a load of traffic out there .. how many are remote weather sensors same with 315mhz ...could be handy in mapping local climate hotspots and microclimates.....
