Hello Alfredo,
Thanks for posting your experience. I had not considered using the exec beacon, but now you have me thinking.
I had considered an approach similar to your MCP3008, but my primary measurement concern was battery current.
Using a 75mv/A current shunt would work but it was messy and didn't have the accuracy I wanted.
The INA260 was the easiest solution for me. However, if I need to add more inputs I'll consider the MCP3008.
At present my five telemetry channels (max for aprs) are battery current, battery voltage, power, cabinet temp and cabinet humidity.
I am going to swap cabinet temperature for solar radiation in the winter, perhaps switch back to temp in the summer months.
I have found the ideal size solar panel but have not yet found the ideal battery. It would be impossible without the telemetry.
Again, thank you for sharing. Your ideas and experiences are quite useful.
Best Regards,
Bill
