Has my washing machine cycle finished?
Has my washing machine finished?
These flows allow for alerting when a zwave monitored device (in this case a washing machine, it could be a dishwasher, or some industrial process) completes a load cycle. It should be pretty easy to convert to a non-zwave supplied input.
Flows detail:
Automatic starting of zwave polling at Node Red start to obtain regular updates from an energy monitor node. (the TKB Home TZ88E Power Meter Socket UK was used in testing, any zwave power meter should work)
Monitoring of minimum power threshold/duration to be achieved for a cycle to be considered started and then not met for it to be considered finished is handled by the power monitor node.
Alerting to a mobile phone (apple or android) via the SIGNL4 node, you will need an account at their web site, a free tier is available.
This is really a simple wrapper around zwave, power monitor and SIGNL4 nodes as a demonstration, and to make it easier for someone to search for.
