Jebao Doser 3.4 WiFi 4-Channel Auto Dosing Pump for Saltwater Reef Aquarium, White (Doser3.4)

First I would like to emphasize that it is critical that your ISP splits your wifi signals into 2.4g and 5g otherwise you will not be able to connect to the doser. Second, make sure when you are setting up the doser to have 2.4g enabled on your mobile device (connect to 2.4 not 5) or the doser will fail to complete the setup.If you follow the steps precisely the doser should work perfectly. I have been running this on my nano reef with acropora and clams and so far it has functioned correctly without any interruptions or miscalibration errors. I would highly recommend this product if you are looking for a basic doser to run off your wifi network and are somewhat tech-savvy should you need to trouble shoot minor setup issues.On a side note, this doser looks great and feels robust! Very happy with my purchase!

I bought this unit to replace an older model Jebao that I had been using for over 5 years. This is definitely easier to use due to the app.The directions aren’t great, but the unit is simple enough that you can get it going with a little patience. Many people have complained about their inability to connect to wifi. I also had difficulty at first, but after simply pausing the 5.0 ghz signal on my wifi router, it connected to the 2.4 ghz on the next try. I have an Eero router which allowed me to simply pause the 5.0 signal for 15 minutes via their app.The Jebao app isn’t perfect, but simple enough if you follow the directions. I also had watched a couple of YouTube videos regarding the app and programming prior to purchase. I calibrated each pump individually and found there to be only slight variations from pump to pump. I plan to recheck calibration monthly just to make sure things stay close over time,and I’ll try to update this review with those results.UPDATE- after 2 months since my positive review the unit has now lost wifi signal 3 times and nearly crashed my system. I have fiber optic service that is extremely reliable. The signal is very strong so there is no excuse for it to lose the signal. I am going back to a non wifi based unit for peace of mind.I previously rated this 4*. Rating changes to a 1*. If you have a reef tank, consistency is what you’re after. You won’t get consistency out of this unit.

Was a pain to get it connected to wifi, but once that was working, it was simple to set up, calibrate, and get running. So much cheaper than other brands.

The media could not be loaded. 1. All 4 heads were squeaky from day 1. I replaced one of the heads with a spare one that was in the box, and it squeaks as well. Then I replaced one of the heads with a head from an older dosing pump, and that one doesn't squeak.2. Wifi configuration is not guaranteed to succeed. Access point mode didn't work without any explanation. As for the other mode , my Nest wifi mesh doesn't support explicit configuration 2.4 vs 5ghz, so I had to turn off the nearest router and hope that phone connection to the other one would use 2.4. Eventually I succeeded, but you can't be sure it will work for you too.3. The UI is pretty terrible. It's counter-intuitive, you need to tap and hold elements, and there are no Save buttons in many places. You just configure something and then tap Back and hope that the changes were saved.4. All of the previous issues fade in the light of this one. The pump randomly screws its config. Sometimes you turn off the program on one of the heads and in a few days find out that it's back on. Currently the app doesn't allow me to disable the program at all, watch the video. It's basically dangerous to use this pump for a reef tank dosing.Conclusion: even though I've happily used 2 other Jebao dosers for years, I consider this wifi 3.4 model a complete junk. The mechanics of the dosing heads, the app design, the wifi hardware and the cloud backend software - all aspects of this product deserve 1 star out of 5.It's going back to the seller.

I have been using this doser for over a year, and while it is still working I strongly recommend looking for other options.Pros1. It works2. Can connect via WiFi.3. Can set schedules for each individual channel.Cons1. WiFi setup is finicky. It is easier to connect to its built-in in WiFi channel during setup. Once configured, you can switch your phone back to your home network. No need to switch back to its built-in WiFi for any maintenance or manual use .2. It loses calibration easily. if you were planning on using this for a Reef tank, so yourself a favor and look for a proven doser. You will easily ruin water parameters within a week or two.3. "Normal" WiFi connectivities are a PITA even if you're router supports 2.4Ghz. It's just bad.-----------All in all, it is an ok doser, but not recommended if the intended use requires very specific dosage that can't have the risk of over or under dosing.
