Have you recently deleted a device from your account? Does it still appear if you close the app and reopen completely?

The Wave Engine LE does not have 0-10v outputs. It has 0-10V inputs. You can not control the pulse 4 using the 0-10v port on the WE LE. only the x4 and full wave engine have 0-10v outputs. As for the xf350 pumps, I assume you have those on direct drive ports on the WELE. You should be able to...

I have started to compile a few google slide presentations for certain topics that involve the Hydros controller series. Here are decks that are currently available: Hydros 101: 0-10V Inputs/Outputs Hydros 101: Calcium Reactors Disclaimer: These references are produced by a 3rd party and...

I have put together a tutorial here on how to do this: Low Power Mode/Prime Power Loss Detection w/ Icecap Battery (or WE/WELE)

Normally Hydros can detect when prime/wall power is lost by using the Icecap V3 Battery backup on a wave engine. Hydros does this by seeing the drop of DC power into the wave engine from 24V wall power to 12V battery power. Then you can configure Hydros to fall back to a pre-defined "low power"...

Depends on your supply pressure. Filters tend to work better at slightly higher pressures

I concur with this suggestion, I have wanted to use certain outputs of profiles that generate multiple outputs for controlling other things.

You can control your varios 2 pump with the 0-10V output by using the Output Type Constant or Return Pump. Set the OFF voltage to 0V and then the ON voltage to your desired ON speed. I use this for my calcium reactor pump. I run it at 30% so I set the ON speed to 3V. Select the output to one of...

Try rebooting the collective via the app.

It would be nice to have a new type of output in Hydros that would allow users to link the state of RED/ORANGE/YELLOW to a physical output. Under this new output type, I would envisioning having check boxes for each alert level that you'd want to tie to this output. So for example if I had a...

Direct Drive ports can only be assigned in the Output Type of Flow Pump only. Switch the pump type and you will be able to select type Varios 2 or 4. You will also have to now make a schedule as well to turn on that pump, but you can easily make a schedule that runs 24/7.

For now use the web app at CoralVue HYDROS App until support and engineering can look into this issue @Carlos

Use LEFT and GROUND (¥). Left is tip. Right is ring. Ground is sleeve.

A live tutorial that I will keep up to date with everything 0-10V Port: Hydros 101: 0-10V

8 is the limit. Hydros will reliably work with 8. Once you go above that it uses more processing power to keep up communication. So while it may work, do know that reliability in communication can be affected.

If the load is low power, FETs sometimes won’t turn off. But they tend to last longer. But for your application I’d go relays

I found another relay module that will take 0-10V inputs directly recently and came up with a design for how to use it with a common DC voltage supply for powering/controlling 4 devices that use the same DC voltage (12V or 24V). I started a new thread for this design here...

Here is a simple DIY project for using the 4 0-10V output channels of a WE or X4 to control 4 DC outputs. This is handy if you have devices that run off a common DC voltage (either 12V or 24V since they are very common for aquarium devices) that you'd have to be able to turn off and on using...

Just be aware this is a preorder.

carlos just posted a fix for this on the fb group for someone else having the issue:
