I would like to share with you a device we have already developed for a year. A couple of years ago I met the problem with the easy integration of smart valves to HA, and after unsuccessful research, I decided to develop my own solution.
I decided to use Nordic as the main chip and Zigbee as a communication protocol.
Main requirements:
easy integration to HA;
Possible to manual control the valve with feedback to HA
True Wireless;
Long time working from a set of batteries;
After researching the market for the main component, I chose the following main components:
Hey guys, just wanted to share some updates we made on our project recently. We’ve been focusing on improving the working time from our battery set, and here’s what we’ve done:
We switched out the LDO for an LP2985, which is more energy-efficient and has lower current consumption.
We added external pull-up resistors to all buttons and switches, which means they now draw less current.
We also fixed a bunch of small issues that were affecting current consumption.
Hopefully, these updates will help us get more out of our batteries and keep our project running smoothly for longer. Let us know if you have any questions or suggestions!
