Hello everyone and sorry for my bad English. With my company we are developing a small monitoring system to acquire parameters via modbus and rs485. Once acquired, the data will be sent using MQTT (amazon Iot) on an Amazon EC2 (ubuntu) on which we create a DB and a webapp. I wanted a tip on what hardware to use.
The system will be installed in quite remote places inside a dedicated ip65 electrical panel with UPS.
For now we are using a teltonika RUT955 for connectivity and as hardware we are undecided
- Raspberry (I'm afraid that after a few years it can break)
- Opto Grow Rio (looks very reliable but the cost is high)
- Siemen Iot 2040-2050 (could it be the best choice?)
- Revolution Pi Core
The workload is not very high. But what matters is the highest possible reliability!
We accept advice on everything!
A greeting and thanks
