I've recently purchased an Jaboa 3.4 dosing unit, and thought I would post my experience using this device.
The unit was purchased from Aliexpress and was brought as part of set that included 5m of tubing and acrylic tank clamp to run the tubing, at the time it cost me £63, and also include a UK plug convertor as power adapter is a 2 pin type. This doser is their latest model, and has 4 channels, there is also single channel unit available.
This model is quite a bit smaller that their previous model.
This is picture of the unit set up, the dosing container where purchased form my local aquarium store, but any old container could be used. Something to be mindful of, that i was aware until recently is that fertilizers will deteriorate over time if exposed to natural light so i have now made a simple enclosure to cover the unit and dosing container and have also ordered some black tubing.
The acrylic tank clamp, not the prettiest so I'm going to look for something a little more discrete.
The instruction that came with the device left a lot to be desired so here is a bried description of how to use device.
The unit only connects using 2.4GHz WIFI connection, you need to connect your phone to this WiFi channel, before your phone will connect with this unit. To connect you need to set up an Jaboa account and download their app on to your mobile. The app seems relatively easy to use, the app allows you to control each channel/dosing head and set programs independently.
Once connected to calibrate each channel/head you hit the three little dots in top right hand corner, and set the time of how long it takes to dose a specific amount of liquid. There are few YouTube videos on how you calibrate this particular unit.
The app that controls the unit seems works on a 24 hour cycle, you can set each head to dose specific amounts of liquid fert's over the course of the day and then set daily (24 hours) intervals between dosages. To get into the controls for each head (channel), you hold down the corresponding channel button on the main page. When you hit the run programme button a green clock icon will appear next to channel button on main page. Please note you also need to ensure device is turned on on the main page (where you select each channel). The on/off button in the individual channel allow to manually control the device.
Relatively easy up to now, this where it gets a little more complicated. To get the unit to dose on alternate days, it seems you have to turn on programmed cycle for each heads on alternate days. However there is an down side if you happen unplug or have a power cut the heads will restart the cycle and result in both heads powering on at the same time, which means the head end up dosing on the same day .
Apparently the older models also had a similar issue and there is a work around that is discuss in the following post:

From my own experience this unit did seem to retain the programmed dose cycle even after being unplugged, and can also be connected and controlled remotely providing the device remains connected to the WIFI/ router.
Really like the new Jaboa doser, as it really easy to use thou i don't have much experience using other auto dosing units.
