My name is Martin and I am new here and in Arduino in general.
I managed to run a raspberry pi based surveillance system on our boat for the last three years, which ran great. The boat is about 1 1/2h driving from my home and it is good to have the feeling everything is o.k. on board.
Now I got the information, that the shore power must be switched off, when I am not on board. I can produce some energy with a solar panel, but the raspberry pi (and the LTE router in the second line) are too battery hungry (1A/h ). As the batteries hold about 150 Ah, I need to find a low power solution with e.g. ESP32.
I guess many weekend hut owners, boaters or campers know well this scenario, so the project could be useful for many users.
Currently I have the following functionality, which I want to maintain as far as possible.
- motion sensor (intrusion)
- water intrusion sensor
- bme 280 sensor (temperature, humidity, pressure)
- battery voltage
- camera picture upload in intervals to an ftp server (extra pi zero w)
The data is sent via mqtt to a broker at home and processed via node red.
The plan is to use a e.g. ESP32 to do the tasks and sleep most of the time. The current drain of the LTE router should be replaced by solar power, but if possible, I'd like to switch to a ESP GSM module later.
I tried many days with the ESPEASY software on a ESP32, but could not achieve all functions and did not get the system running stable, so I guess it is the best to write a new sketch.
Unfortunately I have no programming experience, so this will be my first project. I hope there is a sketch available, that already fulfils some functions and I can modify it for my needs.
Shore power is switched off in two weeks
Any hints, how to start are very welcome!
