I have a sort of odd project I am working on. I have a hand cranked generator that puts out 48 VAC. I am looking to get a HS event or device to fire when the crank is turned...
I have some ideas of how to accomplish this; but I wanted to ping the crowd and see if I can come up with something easier/cleaner.
I have some AC optocouplers from an old project where I monitored the 128VAC voltage inside the washer and dryer to generate a TTL signal that I read into a Flyport Wifi board (kind of like a small Raspberry pi). That would create a socket with Homeseer to report the status of the washer and dryer.
I was thinking about reusing these optocouplers, and maybe using it to to control a zwave closed contact sensor. This would require a battery to power the sensor, the optocoupler and maybe control a relay. Lot of load on the batteries (box needs to be self contained but can be opened).
I was thinking that I also have 48VAC AC to power a circuit; albeit for a short period of time. Just enough to turn on a radio and send a signal. I could rectify the voltage and use a switching regulator to step it down.
I have a RFX transceiver sitting on a shelf, and a WGL800 as well; I am not completely limited to zwave here. Anyone have any ideas or tools I am not thinking of?
