So: yes - you can switch it on/off directly with the button (delay approx. 1 second). Unfortunately, the app does not send any messages when it is switched on/off. However, you can control the Water Controller externally via the Internet using Blooth Bridge (we have already done this from abroad :-) ). Apparently it's also possible to connect Hombli to Alexa and/or Google - but I haven't done that yet. Maybe you could "set" something like a notification. In any case, it would be a good thing if you could control a message! Any settings are made via the app (in my case the one from hombli), but there are also third-party apps that partly support such valves (e.g. Eleison), maybe you could activate push messages there? Otherwise, simply set up a watering schedule for your father, then he won't have to worry about it at all. Connected to the rain sensor, this can even be interrupted automatically when it rains.

Hello, I have been using 2 water controllers for a year in conjunction with Gardena drip irrigation. As relatively little water flows there, I have not opened the garden valve fully, as this does not help. The opening is only about half a turn. Maybe that will solve the problem

We used ordinary batteries, 4 x AA (Mignon) and they lasted a summer without any problems. I would describe the pressure reduction as slight.

Yes, you can simply switch the Hombli Smart Water Controller on and off with the app without using a timer. The controller makes it possible to control the tap from anywhere and at any time via the Hombli app, making it ideal for spontaneous switch-on and switch-off operations, such as scaring away cats. The controller is also compatible with a Smart Bluetooth Bridge, which allows you to control the tap via the internet and create smart scenarios if you need these functions.

5-35L/min

The Hombli Smart Water Controller 2 requires an additional Bluetooth bridge, called the Smart Bluetooth Bridge, to work with WiFi and allow remote control via the internet. This Bluetooth bridge is not included in the basic product and must be purchased separately.

When pulsing, it is possible to water for a maximum of 59sec and then pause for 14min59sec. I don't know if the app is still relevant, I use the one from Tuya

We are happy to place the answer from dready_one here: Hello, you can set anything from 1 min. to 11h 59min. I, for example, have even set the interval. 20 sec. Watering, 20 sec. not watering. over 5-6 min (raised bed). So you can always give the water some time to seep away. Great product, I would buy it again.
