I have a 340 and don't know how to get my alarms working. For the probe temperature and the deviation. Had the deviation set to 10 degrees (it went 50 over the set temp) and it didn't send an alarm. Never got it to work.
I’ve had an RT590 for a month and mine have never worked either. (Alarms, Alerts) Rec Tec has been working on the fix for some time but folks are getting impatient. I also read a review stating that the unit goes to warm mode when the meat reaches its final target temp to prevent overlooking. It does not have this feature .... although I wish that it did. Rec Tec needs to get the app fixed ASAP so that I can sleep during an overnight cook! That’s one of the reasons why I bought it. Better let Rec Tec know that you are having issues.
An extra call or email doesn't hurt. When I talked to them , said they were aware of it and working on it. I told them this has been a known factor for quite some time now.
+1 for reaching out to RECTEC...you may not receive the immediate answers you want, but for now it’s about helping them identify the impact across the customer base...the more widespread the issue appears to be, the greater the likelihood that the issue will be addressed above other less reported issues.
