Aquarium Controller - Raspberry PI 4B Node-RED, Atlas-Scientific i2c Devices, NCD i2c Relay Board

I'm wanting to post an updated Flow. But apparantly the flow is to large to share the code.. So I just have to attach the flow ?

AtlasScientificNCDDeviceFlows.json (80.6 KB)

Had an issue on my project Startup, I couldn't just feed an automatic start for the pump... The i2c Relay Baord wouldn't do it. I had to do a series of carefully timed toggles off, and then back on at Startup to set the Sump Pump and UV Filter Cmnd to ON and actually get them to start.

Interesting. i2c is always a bit tricky.... and relays are as well too...
