Re: piBeacon: presence monitoring plugin discussions

Hi Karl,

Welcome back.

Couple of things to think on when have time

1. Any way of reporting ongoing communication with sensors. e.g data received; even if unchanged?

If sensor is changed - time of last update is recorded with lastSensorChange TimeDate

I would prefer timeAlive or checkReporting or something similar. e.g reported date even if unchanged

eg.
have a wifi rpi that often loses reception.
Sensor data is then unchanged - and it takes a while before I can tell whether it is because the rpi has lost connection or whether there hasn't been any sensor data change?

(Hopefully makes sense)

2. I have a MCP4725 here coming..
https://store.ncd.io/product/1-channel- ... -i%C2%B2c/
From these guys like some previous models.

Looks quite good as can output 0-10Volts and have a variable pool pump which allows speed control on this basis. (from 0-10V)

I note the plugin using input voltage and outs 0-3.3V - any suggestions for when it eventually arrives..

Thanks

Glenn

For the rpi i would use fingscan or UniFi to check if it is online.

Input output voltage are set to 3.3 bolt as those are the save limits for lost sensors and the rpi.

But you can simply scale it if the hardware allows it

Map 10v to 3.3 v
