If you’re more of a fan of managing Home Assistant via configuration.yaml, you can declare the helper there too: input_boolean: Helper configuration Screenshot of helper configuration screen

This will be a single global flag, that all of my sleep-aware devices can watch and respond to. I’ve gone ahead and created one for our flag. Screenshot of Home Assistant Configuration screen They’re available in the web interface under Configuration > Helpers. Home Assistant has the concept of “helpers”, which are just easy places to store an extra little bit of state like this. Introducing a Global Flagįirst up, we need a way of storing the “please stay awake” flag. Let’s avoid adding another protocol and set of messaging concepts in the mix. One of the things I really like about ESPHome is how natively it is integrated with Home Assistant, and the entity model that’s already there. I wanted to document an alternate approach, that avoids the need to introduce an MQTT connection, and sticks with a purely Home Assistant-native approach instead. That solution relies on an MQTT broker holding the message, and the device checking for this pending message on boot: It’s essentially an advertised maintenance mode.Įmad hit this challenge in his project and implemented the solution that’s documented with the ESPHome Deep Sleep Component. When the device next wakes up, it’ll read this flag, and skip a further sleep cycle.

The solution: Publish a flag that says “stay awake”.

It’s incredibly hard to push an over-the-air firmware update to the device when it’s only awake for a few seconds at a time! The challenge: Combining deep sleep behaviour with over-the-air updates. He’s working on battery power, and thus needs to put the device into deep sleep most of the time to conserve energy. ESP-based devices, like the M5Stack Atom, are a great platform for building small automation projects on.ĮSPHome is a great way of rapidly generating feature-rich firmware for these devices.Įmad Alashi – a long-time coworker of mine – recently blogged about a soil moisture sensor that he’s built using exactly this combination of M5Stack Atom + ESPHome.
