I'm working on this again today and I'm making some good headway now. I think I may be on to something in regard to the 10 minute shutoff. Just a little background in regard to my thinking, I purchased the Rain8 weatherproof enclosure
. However, this particular enclosure is not designed for the wifi version of the Rain8. I ended up cramming everything into the box, bundled wires up, etc. but there really isn't enough room for everything to be laid out well without cutting and shortening wires.
This morning I took the wifi adapter out of the box and have it sitting on a chair outside the enclosure but still hooked-up to the Rain8. I can now leave the wifi adapter powered on and the Rain8 runs for the full 30 minutes. I don't know if there was interfearance that was causing a false shutoff command after 10 minutes, the wifi adapter was overheating (it does get warm to the touch) or what the deal was.
However, I have another thread going on CQC's board in regard to another problem I was having that I thought was unrelated, but may be another symptom of the same problem. I was getting time out errors when trying to access the virtual comm port created by Comtrol's software. (That thread is here
There's a page in the Comtrol Driver that shows me a bunch of information including packets that need to be retransmitted. I found that around 25% of the packets needed to be retransmitted. The Help file indicates that it could be a problem with the network, which wouldn't surprise me because of where the adapter is located and the possibility of a weak signal.
However, there are some adjustments you can make in the driver including a "Scan Rate" timer. The Help file says that this can be adjusted for latency problems. I've upped it from 10 ms to 25 ms and I'm not getting nearly the same amount of retransmitted packets. There's also a "Keep Alive Timeout" timer that, "...allows you to set the amount of time in seconds that this device waits until it closed this connection and frees all the ports associated with it." (From the Help File) It's possible there is an issue with this Timer taking over the Comm Port while things are going on which keeps out the programs I'm trying to use the trigger the sprinkler zones.
