The upload procedure for ESP8266 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them […]

Slowly but surely I am looking at the extensions of the “standard” ESP HomeKit accessories, how to implement them. Now I am working on the Battery status. We need some circuit which can effectively measure voltage. Battery monitoring circuit is a traditional voltage divider circuit. I am going to measure 3.7 volt (lithium Polymer) battery.

One of the most important features of the ESP HomeKit project is security. Because it is open source, you can see that no data from you is being recorded anywhere or anything like that. Of course because you program the code yourself, you can decide what happens and not another large company that collects your

After a while all software will be updated or there will be some bug fix releases. So does the software that is needed for the Installation (or setup) of the HomeKit SDK (including perquisites and updates), is the act of making the program ready for execution. Because the process varies for each program and each computer,

When you have created your first HomeKit accessory. Then you probably want to debug your code or change something, but then you need to erase ESP module and re-flash it. This has to be easier. For whom that ready my blog regularly know that I always start with installing LCM (Life Cycle Manager). This tool

The I²C bus communication is one out of three possible communication protocols, the ESP8266 is able to communicate with other devices like OLED displays, barometric pressure sensors and so on. The two other communication protocols are SPI and UART. I²C stands for Inter-Integrated Circuit was invented 1982 by Philips Semiconductor (A Dutch company), now NXP
When I’m coding a new ESP-HomeKit accessory I use the free HomeKit Accessory Protocol Specification (Non-Commercial Version) form Apple. To see how to use the characteristics and what type of options there are for a specific type of accessory. All you need or want to know can be found in this protocol. Overview HomeKit

The ESP32 chip comes with 48 pins with multiple functions. Not all pins are exposed in all ESP32 development boards, and there are some pins that cannot be used. There are many questions on how to use the ESP32 GPIO’s. What pins should you use? What pins should you avoid using in your projects? This blog
