I downloaded roast time 4 and it won’t connect the roaster. Whenever I pick a high temp 290 and the roaster won’t change to a lower temp 220. What do I need to do to get this fixed?
I am not sure I understand your problem. Can you explain it in more details please? Where are you trying to change - from the control panel or from RoasTime? When are you changing the values - in what mode?
I am having a problem:
- I plugged in my roaster to power and started a preheat
- I turned on my computer, opened and updated roastime
- I plugged my roaster into my computer
- roastime says it is connected (serial), but isn’t displaying any data from my roaster.
- my roaster is continuing to preheat as I originally told it to, but I’m unable to control it from my computer.
This is the second time this has happened. The first time, it connected and “synced” normally after I completed the first roast. Lucky for me, I was able to keep my head and follow a previous recipe without the data on my computer and it worked itself out.
This time around, I had to wait until a cooling cycle and then (cringe warning) unplug the roaster before it cooled down. I left it plugged into the roaster then plugged it back in. Now I am able to use my computer to preheat which I wasn’t able to do before. However, I’m still not seeing the info on the graph that I am used to seeing while preheating.
When I go to the active page, it just shows the option to preheat even though I just told it to preheat.
Update: Roastime says it is connected, but not displaying anything at all–it’s not even collecting data from my roasts.
Hey @centralkycoffee ,
Does the comms version show in the settings → info? Have you tried some more rudimentary debugging such as unplugging and replugging after that happens?
Happy to jump on a screenshare to help you resolve.
Thanks!
Hey!
Yes, I have tried unplugging-replugging.
I’m not sure what you mean by “setttings-> info.” Do you mean the little i on the “active” screen?
I am just wrapping up my roasting session today. I am roasting again tomorrow evening if you’re able to talk!
@centralkycoffee Although I haven’t experienced this specific issue, I work in IT and this sounds to me like an issue with your computer rather than the roaster. Are you running it on Windows, Mac, or Linux?
If you’re running it on Windows (just going off an assumption, since that’s going to be most common), you’d normally see “Connected (libusb)”, since libusb is the driver that RT uses to communicate with the roaster. If something went wrong with your libusb driver, Windows could fall back to a serial connection, since USB is Universal Serial BUS and that’s technically its default.
I just checked and RT includes its own driver package to communicate with the roaster, so I’d recommend re-installing RT to see if that fixes the issue. You could try downloading it and just running the installer to see if there’s a repair function or you could completely remove RT and install it fresh. Either way, that’ll likely reinstall the driver and resolve your issue.
Thanks!
I have reinstalled, and I will try that this evening when I roast. Will update.
I am actually on Mac (Air, M2 2022, Tahoe 26.3). I used to be on Windows, but not anymore. I might make a switch back since I have a device that could become dedicated if I get that busy.
Update: reinstalling roast time seems to have worked; As a millenial I’m ashamed I didn’t think of that before posting here 
Behavior still kinda funky though–after plugging in my roaster (which was already preheating), I started Roastime. It was not reading the roaster at all. I unplugged the cable from my computer and plugged it back in but nothing happened. When I unplugged the cable from the roaster and then plugged it back in is when it started reading the roaster’s existence.
For the record, though, it still has (serial) next to “connected.”
Not sure if this is indicative of a potential deeper issue or maybe just the decline of my roaster or what. Would appreciate any input on those fronts.
Do you have another USB cable you could test, just in case the cable is an issue? You could also consider getting a canned air duster to clean the USB port on the roaster, just to make sure it hasn’t gotten dirty.
I’ve got an M3 Mac and I tested it today, but mine never showed (serial), so I’m very curious why yours is doing that. Does someone at Aillio know what the connection sub-status means and if it’s relevant to connection troubleshooting?

Yes, having serial as the sub-status (as you say) is definitely new. It didn’t used to say that or have any sub-status at all.
I suppose I could try and clean the port… Seems like a long shot given that it is working to some extent.
@mcaillio, any input?
@centralkycoffee @striplingcoffee That indicates which USB “driver” you are using. We have historically used libusb, but we are migrating to use the serialport directly. So for MacOS, serial is actually expected. Only Windows should still be using libusb on the latest versions of RT.

@mcaillio Since this is a new migration to the serial driver, and the original post said that this occurred after an application update, could it be a bug with the latest version of RT on a Mac? I tested it on mine with no issue, but I’m running 15.7.4 on an M3 while he is running the latest and greatest on an M2.
@striplingcoffee Did you let your sub processes update when checking? That check would require the latest versions of client and comms service.
@mcaillio as far as I know I did, since it updated promptly after a fresh install. What version should I see to confirm that it’s up to date?
OK, update, I reinstalled while my roaster was preheating and when I booted Roastime back up it was connected and good to go.

This sounds like there may be some deeper issue going on. How often do you roast? Would be happy to jump on a screenshare and debug.
Also, this seems potentially related to Unable to connect Roastime (4.13.6) - #7 by mcaillio . You are both on newer M-series Macs.
Hmmm. Intersting.
I am not planning to roast again anytime soon. Do you need me to roast a full batch in order to get the job done, or could it be fine just having it pugged in and maybe preheating a bit?
Yeah, you don’t need to do a full roast as long as it is replicable
