I have had the eKoral Controller for about a month now. I haven’t had it an extensive amount of time to give an accurate feeling, however I will give my 2 cents worth. As time progresses, and more devices are added to the system my opinions may change. For now, here goes. I thoroughly enjoy the controller, with some major exceptions. As with everything, nothing is perfect. Personally I feel like I am buying a higher quality product. The aesthetics are fantastic and far superior in my opinion to other controllers on the market. It’s like buying a BMW or a Mazda. With that said, I can deck out a Mazda with bells and whistles and in reality be better than a BMW. In reality that’s what I did, I used to have a BMW, now I have a decked out Mazda. This analogy is how I feel the eKoral is right now. I feel eKoral is a BMW (or even Tesla since it's a startup) without any extras. Do not get me wrong. I really like the eKoral a lot. For what I need, and with there future addition of a doser, it works. I have my controller set up to have my temperature locked in. My system now only fluctuates within .1 degree. If and when something fails, I have created IF THEN scenarios to turn off devices. IF THEN are functions that allow you to turn on off devices if a sensor detects something is out of a certain range. I get alerts when my pH is out of range. I set all my alert settings tight to avoid problems. The app on my android is great and easy to use and very easily accesible. That reason alone is why I chose to go with eKoral. Which, maybe I shouldn’t have, but I did. It is also, where I anticipate eKoral to grow even more. As that is where their edge compared to other controllers is. With eKoral’s plan to integrate a web based function in 2019 as well, that will make it even more marketable. I had planned (not sure anymore) to get more sensors that eKoral has, and depending on the quality integrate their auto top off pump. Which will only make my system that more stable and also create a bunch more IF THEN scenarios. My Kessil Lights are connected to the controller. I didn’t have to buy a separate controller. That saved me some money. However, with Kessil’s future lighting systems coming out, it will be interesting to see if this function will even be useful. My lights are daisy chained by an audio jack and for the most part works. The Exceptions: Now, here is the big buts. Not butt, but buts. Homonyms in action. The first but has to do with the power strip. The eK Power 6 I feel is too small for me and needs to have more outlets. Right now I am two outlets short of having everything hooked up to one source. eKoral is competing with Apex, and Apex biggest controller has 8 outlets. The perfect number for my system. I have to obtain another eK Power 6 to have all my devices plugged in or use a 3rd party power bar. I do believe eKoral made that decision for you to buy more devices, and turn a higher dollar profit. However, I think that was a bad decision. If you only need 6 outlets, then you are in good shape. Skip to the next paragraph. If you needed more than 8, and didn’t want the Apex, then you are in good shape, next paragraph. As you would have had to buy more with them as well. I’m just stuck in the middle having to either not hook all my items to the power bar, or shoveling out more money. The second but, is that my system has disconected 4 times so far. I got an alert while sleeping each times. I didn’t hear my phone. Luckily it came back online, and it wouldn’t have been a problem anyway. Maybe it was an update? However, what happens if it didn’t come back online. I can’t tell you. Hopefully after time the kinks will be worked out in the future. Third, even worse the last two days the eK Power strip has disconnected during the night. The first time I didn’t realize it until after 4 hours. The lights didn’t come on. The second time I didn’t notice until after an hour. The only way to get the lights to come back on is to manually power off the eK Power strip and back on. For some reason the pumps had come back on by themselves, but the lights did not. When checking to see if there is power each device it will show up with 0w. If I was on vacation and something like this happened, I could have lost everything. The fourth but, is customer service. If you need help, don’t expect to get a reply till the night time. Since they operate from another country, they don’t have people responding to you till late at night. Also, I went to order their doser and other sensors and they wrote me back asking if I wanted to wait till November to receive all my items. The eK Doser doesn’t come out till November, but the sensors are already available. Since I was wanting the sensors sooner they told me to cancel my order and reorder twice so that I could pay another $15 extra for shipping. From a person who runs multiple businesses, I can tell you that is a no no. I have kids, I use no no all the time. I’m sorry, but having someone jump through hurdles just to give you $15 more is not worth it. For that reason I still haven’t reordered the eK Doser and sensors. I will just wait till November if I order it again. Fifth there are some quirks that need to be worked out which are not as big as the others. When setting up a temperature in the IF THEN function, I didn’t have the option for adding a point in the keyboard. For example if I wanted to add 79.1, I couldn’t. After saving the function (or rule) to 79, I could go back and it would come up with 79.0 in the settings. I could then alter it. I only accidentally discovered that option. Another option for me was to type the temperature (79.0 or 79.1) in another app and paste it in the eKoral app as a workaround. I’m not sure if it is a problem with my phone’s keyboard interacting with the app, or just the app itself. Either way, quirks like that I presume will be worked out over time. For reference look at the photo below for a better understanding of what I mean. Sixth my pH sensor is acting finicky. It spikes to near and around 13 generally once a day which is not accurate. Right now I am running it in a cup of tank water for 3 days. It hasn’t spiked, but I presume once I put it back in my sump it will do the same thing again. Right now I there is no remedy to fix it from having a spike false reading. On to my final but. Returning back to my car analogy, is I feel the eKoral is like a Tesla. Looks great, runs nice, and a bit pricey for a startup. But, Tesla’s also catch on fire. Right now we don’t have a bunch of people racing to buy this product. Most are waiting for others to buy it before they jump in for fear of something going wrong like a tank crash. There are not a lot of compatible products. eKoral has a lot of things to catch up on. However, when they do, much like Tesla people will flock to buy them. That is with the assumption they have someone who will properly run their business and make them succeed. With that said, why were they not at Reefapalooza in California? Apex had a huge setup. eKoral has to be at all trade shows if they expect to break into this market. Why are they not having large stores showcase them for free instead of charging them? They need to do what they got to do to have places like BRS sell their product. A Few Other Observations: There is no user manual. Everything is done by their app and a few little postcard type photos. I’m not sure how I feel about that. The eK Power 6 does not have a mounting template. However, you can download it here: https://www.ekoral.io/assets/docs/eK_Power_6_Mounting_Template_A4_en.pdf When controlling lighting, I wish I could be able to use a chart to see the settings rather than a set of numbers. My presumption that the lighting ramps up over a curve and not a direct change at each time setting. Also there should be an option to add more time settings rather than a standard 6. Some people may be more picky than me wanting more control. There were some other things I didn’t like about the app, but has been resolved. Which is good news, as things I have had problems with got fixed without me saying anything. Make sure when adding devices to the eK Power settings that you toggle the default settings to on if you want devices like a pump on at all times. Somehow either that was not an option when I first started, or I skipped over it. Originally I had set everything to a schedule, but everything turned off at 23:59 till 00:00. For a few weeks it did that, till I found the option to change the default settings to on. Don’t be like me and skip over that box on setup. There is an option to set scenes. If you want to do a feed setting you just click the execute bar after you have one set up to your liking. I have my pumps turn off as well as my protein skimmer. However, this maybe something I just do, but I use to have my skimmer turn off for a longer period of time especially if I am hand dosing corals with stuff like Red Sea Trace Colors. It would be a nice option to allow different devices to turn off for different periods of time rather than having them all set for the same time. Maybe I’m the only person who would like it that way. I don’t know. Just for kicks, maybe eKoral should add a place to make notes. There are a lot of apps on the market that allow you to make entries that keep track of your nitrates, phosphates, calcium levels etc. It would be cool to use one app for everything, and not have to go to another app. Conclusion: Now, I am not sure how many people will read this review. If they do, I’m not sure how many will read it in it’s entirety. I have high hopes for eKoral. Right now it is not ready for prime time, at least not the device I have. It could be a fluke. Maybe mine is the only one with problems. With time, and proper management they can do a lot of good and be great competition giving us more options. Shoot, they should hire me for a good price and I’ll go to all trade shows and show off their products, and offer ideas to make their product better. Exposure is key, but it should be done by the company and not by offering a mediocre few hundred back via reviews. As that can entirely backfire.
