Espressif ESP32 Based Smarthome screen for MQTT. This fork attempts to fix M5Core2 support. Take a look at dev_1_0 branch. Some mounting tips for 55mm frame can be found in wiki.

Screen saver was not activation automatically but after timeout following a touch event.
When activated it was deactivation by touch event and screen remained black.
Due to above issues as of dev_1_0_0 the screen saver is disabled.
Affected version: dev_1_0_0
Target version: rel_1_0_0
To do:
M5Core2 enters boot crash loop when powered by 5V rail. This is caused by axp192 configured to expect external power from USB.
Add configuration option to config.json to specify how M5Core2 is powered (5V or USB) and initialize axp192 accordingly.
On M5Core2 tapping works as expected maybe 6-8 ouf of 10 tries.
Reliability should be improved.
Also motor could be used to:
The touch driver of M5Core2 uses internal firmware and version other than 0x11 has issues.
If you experience problems with touch sensing build code from this repo: https://github.com/m5stack/M5Core2-TouchPanel-Recovery (quite straightforward process especially if you have VSCode with Platformio - just open cloned repo, add M5Unified lib via PIO/libraries and run project task m5stac-core2/Geenral/Upload)
if you see
regA1 LIB Version: 0x300e
regA6 Firmware ID : 0x10
then it is required to downgrade the firmware to version 0x11. To do so choose option "write first model FW (0x11)" and write firmware.
After downgrade you should see
regA1 LIB Version: 0x3008
regA6 Firmware ID : 0x11
With this FW version the touchscreen should be more reliable and long presses should be detected most of the time.
I will leave this issue open as a reference for others.
During plaing with lowering CPU freq to 80MHz with screen saver active suddenly hit a bug in wifi stack?

Currently sntp protocol is used to set the time however M5Core2 has a built-in RTC which could be used to speed-up booting.
Expected drift of about 1 min / month is good enough (www.switchdoc.com%2F2014%2F12%2Fbenchmarks-realtime-clocks-ds3231-pcf8563-mcp79400-ds1307%2F M5Core2's BM8563 is compatible with PCF8563 and maybe more than compatible..
After initial config via web ui the main ui is unstable and M5Core2 reboots often making is very difficult to proceed with configuration.
Once mqttbroker value is set the interface becomes stable.
Minimum workaround is to extend initial config page in AP mode (http://192.168.99.1) with settings related to mqtt broker; at least the address.
