One of the people leading ESPHome here. Let me know if there any questions. Last Saturday we announced that ESPHome is now owned by the Open Home Foundation.

If my understanding is correct, ESPHome need to be re-compiled and uploaded every time the config yaml is changed. Is it possible to separate the binary and the config so that for some config changes, there is no need to re-compile and upload the binary? Thanks.

In practice, this is absolutely no problem. It generally only needs to re-compile a file or two for small changes, which takes seconds, and the OTA update functionality works perfectly so you don't need to unplug it/bring it to your desk.

I’ve got a question that I’ve tried to answer by googling but I’ve never been able to find anything that helps. I have a septic tank alarm system that turns on an audible and visual alarm when the float switch detects that the tank is 3/4 full. There is a pair of NO dry contacts that close when the alarm goes off. How do I monitor whether the contacts are closed or open? I assume with a GPIO pin, but I’ve never been…

> How do I monitor whether the contacts are closed or open? I assume with a GPIO pin, but I’ve never been able to google this question and find anything of use. Without making assumptions about the microcontroller used, attach ground to one of the contacts, then attach a GPIO pin, the other contact, a 10k resistor (or 100k), and VCC together in series. The microcontroller should periodically read the GPIO pin. If it…

You're assuming the tank switch is low voltage.

The very first thing to do is read the manual for the installation and/or parts used. Second, approach the tank setup with a high voltage multimeter and carefully and safely take measurements of what you might be dealing with.

I've got 20+ devices running ESPHome, about 3/4 of them are part of my Home Assistant network, and maybe 6 or so that are standalone and just using ESPHome to talk to MQTT for other stuff (cheap Chinese weather station that I replaced the insides of with an ESP32, etc).

How do you monitor your rain tanks? I tried ultra sonic sensors but they invariably oxidize.

There are new 60ghz sensors available that can do this (they can see through walls so you could have the sensor completely enclosed (maybe even potted in epoxy?!)). Sparkfun/Acconeer A121/XM125 is what I'm using,although not in this context, it's for my robot.

Could you recommend a good component for security purposes? Like if someone enters my flat without breaking in (I rent). The docs list a bunch of options... do I go for motion & presence or binary presence detector? Which sensor is better (and most cost effective)?

Depends on your threat profile and budget. Specifically if you're worried about your door opening, you can use a magnet and Hall effect sensor(or reed switch). Another thing you could do is PIR, but the cool kids are playing with 60GHz pulsed radar, which does presence pretty well (I've recently tested that the XM125 radar I just got can pick up my breathing and detects presence from the other side of 2x pieces of 3/4in sheetrock).

I'm definitely not a cool kid:) I was considering putting a camera in the flat and hooking it up to a visual motion detector but that would be a bit expensive probably (would probably need another server in addition to home assistant...)

For home security I use PIR motion sensors in the main rooms feeding into Home Assistant which has a presence service, Eg it knows if we’re home or not based on whether our phones are connected to the home wifi. If we’re not home + it detects motion, it pings me.

Nice. Home Assistant looks easy to integrate with ESPHome... Though I don't yet have either.

I have a pet project I have been meaning to work on:

1. Lookup the local transport API to see bus arrival timings for the stop near my home

2. Display the timings for three main buses so that can either be a bigger display or three smaller displays, one for each bus. Don't have to be high res but relatively larger and bright e.g. a 7 segment display (3 segments for bus number and 4 for showing arrival time in mins) - basically family members should be able to view it from a distance a glance.

3. I should be able to update this over wifi (or via a some low-powered device like arduino/raspberry pi etc. connected to it). If it can run via AA batteries, even better.

I know how to do the first but no idea about the second - I have never even soldered anything in my life. Would be great if more knowledgeable folks can provide some pointers.

I use an ultrasonic sensor and ESPHome to monitor the water level in my sump pit. Depending on what you want out of your septic tank monitoring, this may be a useful option.

Yeah that's overkill. But PIR and esp32s would work for the most part. (don't rule out the radar, it's only $50 bucks at Sparkfun lol I just got it working the other day, it's pretty awesome)

The ESPHome project is unusually competent, user-centric, and almost uncanny in how well it works. I'll tell you what I want, though. I'm not sure this is in-scope for ESPHome, or how it's possible to even implement cleanly: I want to be able to make devices which have tight feedback loops and more complex on-board algorithms What I really want is e.g. a light sensor controlling lightbulbs. Here, I want the lightbulb…

I use Home Assistant for doing most of what you're asking for. This integration works great for adjusting light level and temperature: https://github.com/basnijholt/adaptive-lighting.

My home has an ERV and I use a couple Shelly relays (one for power and the other to boost airflow) integrated into HA to modulate the amount of fresh air I bring in, currently based on indoor/outdoor temperature and humidity. I don't have an air quality sensor, but if I had one I could easily integrate that into my automations.
