Fixed the device creation with the new builds.

And the manual duty mode had some issues, all fixed (I think). There's now three different duty modes.

Would this https://www.amazon.com/dp/B00E6JWIII..._wufrub0A83FJQ 25a SSR work for switching the pumps via the Pi? Or is there something that would work better? I am using two 120v chugged pumps.

Yup, more than powerful enough, all I know is that SSRs are more designed for high rate switching, relays will work just as well and have less heat dissipation. I'm not an electrician though

It's not possible for me to fit in any extra relays though - so, you're saying there potentially would be a way of linking a single GPIO to two sensors/PIDs in a single configuration file, with having only one of those PIDs in command at a time.

Just for you jangevaa, you can now hide devices/temps from the WebUI, even if they're not setup. When you're in edit mode you'll see all the devices, and when you click the title of a device to modify it, there'll be an extra button, "Hide" or "Show" to change the state. Click it, and when you've locked the UI the elements will be hidden.

In theory, you can run two separate elsinore instances on the same device, just don't cross the GPIO outputs, or things'll get weird.

For the pumps I would just use regular mechanical relays. SSRs are great for loads that need to be switched repeatedly but they get HOT and need to have heat sinks and thermal management planning. Standard mechanical relays do not have that limitation and are perfect for things like pumps or valves where you won't be using PWM/PID. You can use SSRs for pumps, but make sure you account for the heat. There probably won't be nearly as much heat with a 2A pump as there is for a 23A element, but it won't be none.

The SainSmart 4-channel relay module on Amazon should do well for you. <$10 and leaves you some room for future expansion.

That's the one, they must be monitoring this thread because it was just over $9 yesterday. For its current price, another $1.70 gets you the 8-channel board.

If you're willing to wait for shipment from China, you can get inexpensive relay boards directly from SainSmart. 2-port = $1.99, 4-port = $6.99, 8-port = $8.99
