This is a bug in the current app version. However if you switch to the Tile view you can override them from there. This is aready fixed in the next app release.

All you need to do is reboot the controller(s). This is being fixed in the next firmware.

From looking at your video it is clear that the cycle you are getting is almost exactly 1 second, not 0.4 seconds. The Hydros times indicate the duration of a full cycle (so if you set it for 1 second it does 1/2 second on, 1/2 second off) It appears that the Maxspect time indicates a half cycle...

I think you are looking for the Hyrdos dynamic dosing. It does exactly this.

The 5 volt output on the sense port is regulated and should be pretty accurate. However as has been pointed out it is deliberately current limited. There is only 100 mA available which is shared between the sense ports and 0-10V I/O on a given device. None of the Hydros sense accessories use...

Blocking client to client communications is kind of the definition of a guest network. The idea is that if someone is using your WiFi to access the internet you don't want them to be able to access your local devices. So this is working pretty much as expected. A dedicated WiFi access point for...

That feature is in the app released earlier this week.

The fill pump on the AWC should have a maximum on time that is long enough for your fill pump to bring the water level back to normal and then some. So here is a typical sequence (assume the max on time for the fill pump is set to 120 seconds) : Drain pump runs for 30 seconds lowering the...

I am not very familiar with the reefmat at all but it seems like you could leave it's normal sensor connected but deep in the sump where it is always wet. Then connect the hydros level sensor to the hydros and let it turn the whole thing on and off based on the hydros level sensor. If that...

iOS and Android are completely identical. There is also a web app that can run on any computer or mobile device that is identical except that the web app cannot be used to add new devices or connect using bluetooth. You can have as many sessions open as you want.

After rereading your post I realized that you may not actually be looking for a 24V contactor. If you can accept a 12V contactor then the normal Drive ports on Hydros devices could run the relay. 12V contactors are harder to find but they do exist. Here is one example (among many) of a suitable...

It wont be available for a while, but a Kraken provides 24 V outputs that could run a contactor easily.

Just to clarify slightly what Danny said. In Bluetooth mode the phone needs to have internet access but the Hydros devices do not. So your phone should still be able to reach the internet via your cellular provider just as Danny suggested. If you have WiFi outlets then your WiFi will need to...

It is probably easier to search for RS-485 cable, they are the same impedance. Belden 3105A is a good example. But this is expensive cable. Unless the distance is large you won't see any difference between 100 and 120 ohm at these frequencies. You need a twisted pair plus a ground.

The Wave Engine is primarily for flow pumps. While it can be used to run skimmer or return pumps, the only real benefit is elimination of a brick and a controller. Now that the Kraken has been announced you might want to look into it. It can replace the bricks on ANY 24V pump, but it does not...

The problem with measuring voltage is that there generally isn't any. Consider that you are measuring the voltage between a ground probe in the water and the electrical system ground. That is a very low resistance connection, should be much less than 1 ohm. Assuming 1 volt across 1 ohm. That...

There are some interesting ideas here. The biggest issue though is that the leakage currents involved are very small. 5 mA will cause a GFCI to trip. So anything above 5 mA is irrelevent. But measuring currents that are typically below 1 mA is going to be virtually impossible with just a 0-10V...

I was wondering how important it is for the moonliight to be dimmable? I have seen arguments that all you really need to do is vary the "on" time to correspond to moon rise and moonset throughout the 28 day cycle. Is it also necessary to vary the brightness to correspond to the amount of moon...

This hasn't been incorporated into the system yet but I have actually implemented the lunar schedule on it. I plan to add it to the production software by the end of the year. Inititally though the LEDs themselves may be somewhat of a DIY item. The mounting requirements are so different from...
