Are you planning to 3d print some boxes? I also see your transmitter there for a mere 3$: http://www.seeedstudio.com/depot/nRF24L01Module-p-1394.html<br /><br />These AVR chips, despite being old, seem to be a decent choice for the home nodes. I'd probably go with them as well if LLVM/Rust supported it. Meanwhile, I've ordered STM Nucleo L1 board (ARM) + Bluetooth LE extension to play with. Will keep looking for integrated variants with batteries, like the one you have ;)Anonymoushttps://www.blogger.com/profile/10669209464308202279noreply@blogger.comtag:blogger.com,1999:blog-4841270916317321219.post-55159826078863093782014-10-06T20:13:51.108-07:002014-10-06T20:13:51.108-07:00I did not spend much time researching mesh network...I did not spend much time researching mesh networks on nRF24L01, just know there are many implementations.<br /><br />For a wireless sensor node i found a neat solution here: http://www.seeedstudio.com/depot/DevDuino-Sensor-Node-V2-ATmega-328-AAA-battery-holder-p-1850<br />It gives you AVR + nRF24L01 in compact form factor, powered from 2 AAA batteries. Power consumption solely depends on efficiency of your firmware. The idea is that most of the time system is in deep sleep, awaking periodically by hw interrupt to perform a job and to send / receive data.

I like the way you are thinking :) Confir...Awesome! I like the way you are thinking :) Confirms that I'm not entirely crazy with this. I haven't seen these ESP8266 and nRF24L01 things. The former seems to have a neat cost of 7$, even though I'm curious if wifi energy consumption will bring you any trouble. The latter - what protocol does it use for the mesh networking?<br /><br />Computation-aside, I'm a bit puzzled by the task to connect the MCU with an energy source, RF transmitter, and a sensor into a meaningful box. I assume I'd need to either use the bulky (and expensive!) devkits, or design a board myself from scratch, which seems to be a huge task on its own, especially for an unexperienced noob like me. How are you gonna wrap these nodes into boxes?Anonymoushttps://www.blogger.com/profile/10669209464308202279noreply@blogger.comtag:blogger.com,1999:blog-4841270916317321219.post-30890625254224830902014-10-06T18:43:26.225-07:002014-10-06T18:43:26.225-07:00I'm kinda in the same boat :)
Completely agree...I'm kinda in the same boat :)<br />Completely agree with you about this craziness of the protocols, vendors and interoperability. Personally I did not make my decision just yet about a communication backbone in my smart home. Most likely it will be WiFi network on ESP8266-based nodes with custom binary application protocol. Or a mesh network on nRF24L01-based nodes. <br />Either way, I'm going to use Arduino or bare AVR micro-controller (C/C++) on nodes and some ARM-based board for "ground control" (Scala + Akka :).
