new for 2026:

v4.1.0, 7/10/26

We’ve added the option for spaces in Wifi password (already present for Netname). Somewhere we’d heard that spaces in passwords were not allowed, but we’ll leave that to someone else to enforce. We have no problem with spaces. 

We’ve reduced the pre-soak factor by 33% to reduce overshoot. We were a little too aggressive with the pre-soak for some folks. We welcome your observations on this. Thee’s lots of different coolers out there. Should this be user- adjustable?

We fixed the failed 12:xx AM turn-off and turn-on. Simplfied the mechanism a bit while we were at it.

v4.0.9, 6/10/26

timed ON and OFF now work in Manual mode

pause mode touchscreen now works properly in Wide (horizontal) mode

no longer freezes on alert screen when sensor is UNpaired and Option > Setup > Sensor is selected

v4.0.8:

physical size is reduced and all plastic parts redesigned. Many small changes to electronics and software, both bug fixes and enhancements

pause control: added days, hours for greater flexibility

pads pre-soak: added variable pre-soak duration

time zones: (added late 2025) All US timezones are now supported in setup

new for 2025: Besides the more curvy exterior, higher quality 3D printing of all plastic parts, and improved buttons on both the controller and the sensor, the controller now boasts surface mount technology, a machine-assembly process that produces a higher quality, more reliable result. It also has a bigger power supply that supports simultaneous Wifi and Bluetooth access, in preparation for eventual Internet Of Things integration. There’s a new Pause function, and some further refinement. Did we mention the customer-requested Fahrenheit/Celsius ability? (We pushed that out to customers last year)

new for 2024: The Roadrunner Comfort can now update itself autonomously (assuming you’ve connected it to your home wifi network). Each evening, between 1 and 5am, it will log onto our server and see if there’s a firmware update. It if finds one, it’ll quietly update itself and restart within a few minutes, picking up where it left off, no user intervention required.
