"Rotimatic is the world's first robotic kitchen appliance. It measures atta, mixes and kneads it to make perfect dough balls. These are flattened and cooked into round, soft and puffed golden brown rotis. All in 90 seconds!"
"From dry flour to freshly puffed flatbread in a minute. This is possible with a 32-bit microprocessor that harmoniously orchestrates 10 motors, 15 sensors and 300 parts in parallel. The 10 motors work together based on the data from 15 different sensors, which measure things like temperature, position and the most complex and important metric, that is, consistency. It manages all processes seamlessly to save every second possible."

What could go wrong with such harmoniously orchestrated symphony of motors, sensors and 300 parts?

Website Support Chat
>> Hacker says... Hello, I am assisting a friend in repairing their machine. Can you please give me any information on what the error code "0x6" refers to? When plugged in the screen comes on when pressing power, but only displays that error code with teh message "Trouble powering on!". You will be notified here and by email (x@hacker####.com) >> rotomatic says... New Delhi, India D Hi , Thanks for reaching out! We've heard you're having a bit of trouble with your Rotimatic Unit. To sort this out quickly, we recommend connecting with our support team through the Live Chat option on the Rotimatic Application. Just start a chat when you have your Rotimatic handy for troubleshooting (if needed). Before you begin, make sure your Rotimatic is switched on and connected to Wi-Fi to avoid any delays. (Snip how to get app) (Snip screenshots of how to "Contact Us" inside app) >> Hacker says... Can support contact me directly via e-mail or other means? >> rotomatic says... Hi, You can call up our support team directly by calling on +1 475-405-3257 or email to support@zimplistic.com the team will help you regarding the same. >> Hacker says... ThanX!
Initial Support Call
@21:30 hours on a Friday call support phone number provided. 10 minute call with Clare after very brief hold.
>> Hacker says... I'm trying to get more information on an error code. The robot is having trouble powering on. >> rotomatic says... [Some pleasantries and such] Can I get your name? >> Hacker says... ####. >> rotomatic says... Can I get [xyz] information about machine? >> Hacker says... I'm sorry I can not provide any additional personal information at this time. >> rotomatic says... are there any red lights on the side of the device? have you tried pressing each buttons 5-8 times? kindly make a short video of turning on the machine, and pressing buttons. use the automatic application to connect and do a 30-60 minute video call. if not now a session can be scheduled for anytime when you're available [day or night]. >> Hacker says... Can you provide me with any more specific information about error code "0x6"? >> rotomatic says... it's a trouble code that indicates the machine is not able to fully turn on. [mutually exchanged pleasantries and conclusion of call]
Follow-up Support Call
@15:00 hours on a Thursday call support phone number provided. 10 minute call with D.
>> Hacker says...
I'm repairing a machine and have followed the directions from support earlier.
I'm still having some issues getting the machine to start up.
I've replaced the blown Thermal Fuse and looking for the reset procedure.
The device has gone from a 0x6 error to 0x5 with a Later option.
After doing the initial start up homing it lands on a error message about too hot.
{Further discussion about connecting to the internet and using the app for support}
{Discussed various reasons this isn't an option, asked about off-line update options}
Can you provide updated firmware so I can attempt a update via USB Thumb Stick method?
>> rotomatic says...
{Some consternation over who/how the machine was opened and repaired}
Send an e-mail to support with your information for additional follow up.
{Discussed a few other details and concluded call}
Support E-mail
- Sent an e-mail to support [at] simplistic [dot] com with general inquiry for firmware
- Got an instant automatic response to the inquiry
- 2 minutes later Jason messaged that they were looking in to it
- A few minutes later they sent information on update and copy of firmware
- Intructions:
- Use 16GB or smaller USB Thumb Drive (Worked with 512MB)
- Format with FAT32, not quick format (Worked with FAT16)
- Extract Zip file
- Copy
update.imgto USB Thumb Drive - Insert USB with machine unplugged
- Plug machine in, wait 60 seconds (should here ~20 sec tone)
- Machine should reboot itself, usual quick beep
- May still have invisible error
