i have got a WeMo switch that is plugged into the wall, and then the power for the Pi is plugged into that. At any stage that I notice the FO has locked up, I can remotely cycle the power, and everything is reset - so far it has been working a treat.
In order to make it work successfully though, the wiring gets a little bit messy. From the WeMo, power goes into an external hard-drive, usb all-in-one caddy. From one of the usb outputs is power to the Pi, from another is power to the FO unit. The FO unit has no batteries in it, so when the power is recycled, it will reset. Yes, this means that the time is always wrong on it as well as other settings, but that becomes irrelevant when reading it with weewx anyway. The usb caddy is also connected to the Pi via its data port, so the Pi can read the caddy. There is a 2.5" laptop drive also in the caddy, when the Pi initially boots it hands over the the HD to prevent wear and tear on the SD card. One of the issues I have found, is that the WeMo device remains "off" if there is a power cut. We have a few of those where I live. Yeah, I could go down the route of a UPS, but it's a little excessive for something that's not really mission critical. The solution I found was an IFTT recipe. It checks if the WeMo power is on, and if not, turns it on - it works in seconds. This got me to wondering if I could make another IFTT recipe - on that checked if the Pi had read th FO in the last say, ten minutes, and if not, turned the WeMo off. The first recipe would then turn it back on again and presto, we're up and running again. More thought and research is require for that one though. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
