Years ago (2021) I ended up with a pair of rather different little M5Stack units — an M5 Tough and an M5Stack Core2/M2 — and yesterday decided they deserved something more interesting to do than sit around running demonstration software.The answer was ESPHome.The idea was simple enough: turn both units into compact, touch-sensitive information displays connected to Home Assistant.

Of course, as is often the way with these things, the implementation became rather more involved — but the results have been worth it.The larger M5 Tough has a touchscreen, which is now divided into simple control areas.Touch one side of the screen to move backwards through the information pages, the other side to move forwards, and the centre section toggles the display brightness.

The smaller M5Stack unit has three physical buttons (well, touch buttons anyway) along the bottom, so the same basic controls were adapted for those instead.Both devices now display useful information from Home Assistant, including time, date, indoor and outdoor temperatures and humidity.There’s also a detailed weather page showing current conditions, cloud cover, wind, UV index and atmospheric pressure.

And because these are connected to Home Assistant, I couldn’t resist adding a more practical feature: an automatic 5G router warning page.If the router goes offline, the display switches to a rather obvious red alert screen and returns to whatever it was showing when the connection comes back.What I particularly like about this project is that ESPHome makes these little devices genuinely useful without requiring a separate server or a complicated custom application.

They become part of the existing Home Assistant setup and can display practically anything that Home Assistant knows about.The two units are quite different physically, but the finished result is surprisingly consistent: a pair of smart little information displays that are always on, easy to read and easy to control.And, naturally, now that they are working properly, I’ve started thinking of more pages to add… For the sake of it, here is the code for the two of them – beware the code may be improved arbitrarily over time – and better self-documented – but it works – Core2 first then Tough.

You may notice a trend in my recent ESPHOME blog entries – I’ve starting to put all my WiFi SSIDs in for when moving devices around.Oh and they both have WebUIs – current TOUGH WebUI shown below.esphome: name: core2-clock friendly_name: Core2 Clock on_boot: priority: -100 then: - delay: 10s - lambda: |- id(router_monitor_ready) = true; esp32: variant: esp32 flash_size: 16MB framework: type: arduino psram: mode: quad speed: 80MHz logger: api: ota: - platform: esphome wifi: networks: - ssid: !secret wifi_ssid password: !secret wifi_password - ssid: !secret wifi_ssid2 password: !secret wifi_password - ssid: !secret wifi_ssid3 password: !secret wifi_password - ssid: !secret wifi_ssid4 password: !secret wifi_password - ssid: !secret wifi_ssid5 password: !secret wifi_password power_save_mode: none post_connect_roaming: true ap: ssid: "Core2 Clock Fallback" password: "5uKWDKfAoKjs" captive_portal: # Web interface and OTA update page.
