Making WiFiManager compatible with MySensors 2.3.2

October 6, 2021

Its not bug but a workaround just in case if any one is searching for solution. I was successfully using WiFiManager with MySensors 2.3.1 but after upgrading from MySensors 2.3.1 to 2.3.2 i was unable to compile ESP8266 gateway sketch and had error

Arduino: 1.8.10 (Windows 10), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

To fix this iissue you need to comment out MySensors code in two location in core/MyGatewayTransportEthernet.cpp may be there is better way but this is quick fix. Comment out line 49 to 55

Resizing the USB SSD on Raspberry Pi

General Help

Default way to resizing SD card with raspi-config is not going to work on USB SSD disk so we have to do this old fashion i.e. command line fdisk. Let change partition table with fdisk. You need to remove exiting partition entries and then create a new partition that takes the all the free space on the disk we have. This will only change the disk partition table not the data on the disk. First Part of this post about:…

General Help, Lets Build

There are few ways to connect Serial Gateway to Raspberry pi. The easiest one is via USB port to raspberry pi. Due to the size of raspberry pi zero i prefer to have small PCB which will serve me purpose of gateway, zone and boiler controller. This can reduce the cost of having multi zone smart heating at the same time. Connecting Serial Gateway on Raspberry Pi Zero GPIO Raspberry pi GPIO are 3.3v tolerant but we have to use…

With a bit of spare time over the Christmas break, I have been working around with my google home and PiHome. I was ready to buy a boost console from PiHome but decided to try my own attempts first. Rather than using a physical button, I decided to try voice commands instead. Below is the description of how I got there – I’m sure you can think of a number of improvements/ a much simply way of coding this, but…

Low power relays boards are one of the most common interfaces between a Arduino/Raspberry Pi and the outside world. These relay boards provides electrical isolation between the low voltage circuits of the Arduino/Raspberry Pi and the high voltage loads. So why this I2C relay board? i2c relay boards only requires 4 pins from Arduino/Raspberry pi to control up to 128 relay. Raspberry Pi i2c Example of controlling i2c relay board from Raspberry Pi 1 – +5V 2 – GND (common…
