One of the goal is to track humidity in every room to figure out the best moment to ventilate the room optimised the energy spent to heat the rooms. In order to achieve that, a threshold should be configured in the gateway to trigger notification to the users (via mail, ams, instant notification or whatever works). text/html 2014-03-27T20:47:52+00:00 Anonymous (anonymous@undisclosed.example.com) https://diy.vdesmedt.com/hellohome/energynode/pulse?rev=1395953272&do=diff Pulse count Pule counting should support : * Hall sensor * Optical sensor * Third party sensor like Itron cyble Features : * The node will send the total pulse count every time it encounter a pulse (never less than once per 10 sec and never more than once per 2 sec). text/html 2014-03-26T21:25:59+00:00 Anonymous (anonymous@undisclosed.example.com) https://diy.vdesmedt.com/hellohome/energynode/temperature?rev=1395869159&do=diff Temperature monitoring Temperature will be measured with two different sensor : DS18B20 and DHT22 which is also used to monitor humidity. Both uses OneWire bus. I need two sensors because in some case, I want to monitor more than the environment temp (i.e. Hot water temp residing in the boiler)
