Most judges know that these machines are not the most reliable. If this is your first violation, there will probably not be too much to worry about. I don't know of any court or pretrial services officer that would recommend a violation on a one time violation.
However, contact your lawyer and verify that there will not be significant consequences.
Your panic was smart and you seem to have done the right thing, except you need to talk to the probation officer responsible for monitoring interlock. It may be your regular probation, so that's the place to start unless you have already been dealing with someone. You want to head this off before it is referred to the judge, if you can. It is not good for the judge to see you in court. Once the judge starts recognizing you, life is not going well. But as the attorney said before, it it gets to court, you will need to explain your situation. Unfortunately, my experience has not been as good as his apparently because I have seen judge thrown someone in jail for one violation, so you must be careful. Most judges give you one alleged violation, but then they don't remember whether it was a situation that is defensible like this one and just count to 2 and throw you in jail. So not pretty, do keep calling to talk to your lawyer or get one that will talk to you.
