Appliance current draw monitor - mpalitto/HomeHacks GitHub Wiki

PROBLEM:

when more than one appliances are working (eg. cloth washing and dish washing), some times, the circuit breaker will shut the electricity for the whole house off.

ANALISYS:

during the working cycles of the appliance there might be a short time when the current draw is at his peak, and if the peaks of more appliances happen at the same time the circuit breaker will trigger.

SOLUTION:

The idea is to have a profile for each appliance of the current draw for their working cycle, in particular their peaks values and duration. From that figure out which one is the most common scenario and thus monitor it, when it is going to happen prevent it by removing temporarily power to one of the appliances in use.

ALTERNATIVE STRATEGY:

figure out the one most demanding and connect it to a UPS, monitor the current draw and when a peak is about to happen remove the power which in this case will be provided by the UPS. In this way there will not be the need to monitor more than one appliance.

PLAN1:

monitor dish washer, cloth washer and Nicolo bathroom. My understanding is that the problem will happen when these are working at the same time (Daniela uses a electric heater for Nicolo bath time).

DOC:

inizia a loggare da ERLI-BACKUP: screen -S current -dm /root/current.sh

per visualizzare i valori: screen -r current

per terminare: screen -S current -X exit
