Least Cost WiFi Temp Controller?

[ultravista]

I am looking for an inexpensive WiFi temperature controller, preferably one that logs.

Any suggestions?

Define "inexpensive"

$50-$75

I have a digital Johnson controller now and looking for something that I can monitor/control via WiFi with data logging.

I think you might get something similar to the Johnson for that price. I think you are talking a LOT more for data logging.

But I will be watching in case I am wrong.

DIY brewpi will easily get you there under that price tag.

A Pi Zero for $5 at Microcenter, a Chinese Uno R3 for $10 on Amazon, 2 or 3 wired DS18B20 probes for $3 each on eBay, a good Wifi dongle for $10 on Amazon, one 4.7K ohm resistor, and an orphaned microUSB phone charger will build one wifi-capable BrewPi controller well under that budget...

Cheers!

Pi Zero only has a single micro-usb connection for USB and one for power - how would you hook up a wifi dongle without some sort of USB hub?

Ah - you're right - my bad, I forgot the zero only has the one port.
Ok, add a passive hub for $5 and a 9V 1A wall wart to power the Uno for $2.
Still below budget...

Cheers!

Nicely Done!! :rockin::rockin:

Thanks.
I would have use a Po Zero if I could buy one for $5. The Pi build would cost more for WiFi, hub, SD, etc, but it is more powerful and I believe the system is more stable.
Now that I have gone so far, I see no reason to switch.
