Datamailbox data loss on power cut - heyjay - 27-05-2026 Hello, I'm using an ewon flexy 205 with historical logging and I configured datamailbox for our IOT application. I discovered recently that I'm missing sometimes data. After some investigations, I pointed the problem out. This happens when flexy loses Internet connection before a power cut. All data not sent between the Internet disconnection and the power cut are lost. If the module loses internet but reconnects before a power cut, then I don't lose any data. So it seems the buffer is flushed when flexy is powered down or the datamailbox engine is not totally reliable. In the same time, I'm using a MQTT BASIC script for another IOT application and I don't have the problem, all data are retrieved when ewon restarts and is connected back to Internet. Does anyone can confirm if it's a known issue with datamailbox? Thanks a lot RE: Datamailbox data loss on power cut - simon - 02-06-2026 Hi, No, this is not a known issue and this must be investigated. I saw you created a support ticket for this. |
