Device OS: 0.7.0
I have an Electron 3G monitoring battery voltage (Victron MPPT solar charge controller) at our summer house in a remote location. The setup has been working flawlessly for 6 months. On startup the code reads the battery stats from the charge controller, sends them over MQTT and then goes to sleep. I’m using SYSTEM_MODE(AUTOMATIC) and 3rd party SIM.
On Thursday March 27th 11:00 EET I lost access to the device and haven’t been able to figure out what went wrong. It’s not able get a cloud connection. All I’m getting is Last Handshake: Mar 27th 2019, 11:09 am.
What I know so far:
- The device is registered to the network. I’m able to send a SMS message to my device and get an immediate delivery notification.
- According my operator’s billing stats the device is generating GPRS traffic (exactly 0.54Mb each day)
What is the status of my device? I’m presuming Mar 27th 2019, 11:09 is the last SUCCESSFUL handshake. Is there a way to find out whether there has been unsuccessful handshake attempts?
