Onion Omega for Heater Meter?

Bryan,

I have seen mention that you might go with C.H.I.P. as a replacement for the raspberry pi with future development of the HM. I know there is a old thread on here mentioning the Onion Omega that you had responded too. Back then it was a kickstarter and still vapor ware. Today it is real and being developed for. The app store and some features are still in beta, but it all appears to be moving forward quite well.

Based on what I know about the Onion Omega it seems like a better fit for replacement of the Pi. It appears to have some advantages, not the least of which is that it is already available. It runs OpenWRT and the developers have a web interface dashboard implemented. The onboard wifi relieves you of maintaining drivers and us finding flaky dongles, it also supports being a client and AP simultaneously. It is smaller than the CHIP (1/4 the Pi) and appears to use less power. They have an arduino expansion and appear to implement avrdude to interface with it. Its major short coming is storage space, but the usb port on the expansion dock can use USB storage. It also is not as cost effective as the CHIP, but its less than the Pi at $20USD for the device or $30 with dock.

I love what you have done with the HeaterMeter, but I am not a programmer and merely dabble with these things at a very low skill level. Given this I realize my next statement comes with the oblivious naivety of my 'simple' view point. It seems like the linkmeter package could be adapted as an 'app' on this system without major overhaul?

I have two of these and would happily send you one if you would like to experiment with it.

$20 for that is pretty steep, when compared to something like the $9 CHIP or $6 NodeMCU

There's also an updated RasPi A+ coming out this year with onboard wifi, so it will be interesting to see how that's positioned in terms of price.
