DIY HomeKey locks via Reactor

So you flash Shelly devices?

[therealdb]

I’m mostly on tasmota and Shelly because it’s easier than coding, but I’ve done a couple of things in the past (in arduino/c++ as well). You all know I’m a huge fan of Shelly since a long time.

Right now I’m toying with espresence and bt relay via esphome and I’m moving most of my moderately complex login to MSR. I’ve learnt how to write complex expressions lately, so I’m moving lots of logic via mqtt to rules and expressions. I’ve also generated mqtt messages from existing devices/integrations to easily have devices mapped under MSR.

Next things on my journey are templates to get esphome Bluetooth relay for home assistant directly into MSR, but that’s another story.

Long story short: no need to write custom firmware, unless you have very specific use cases.

Thanks for that. In my case, I do!

You may be surprised, but esphome and tasmota have plenty of ready to use templates for sensors.

No... where I've previously used an ESP8266 or ESP32 with a relay (output) or contact closure (input), I switched to Shelly. I'm only flashing various ESP models, and things that look like ESPs (e.g. Sonoff plugs).

You’re right. There’s something that looks useful here:

Pulse Meter Sensor

Instructions for setting up pulse meter sensors.

I just have to read up more about their ecosystem…

I'm in that age (with quite a busy schedule for work) that I'm trying to glue together instead of re-write from scratch. in fact, I have less things to try than in the past. plus, all these projects are highly maintained and I could concentrate on my own logic

@akbooer I am using an ESP32 with a water passage valve, which generates pulses, and thus controlling the water flow in my house, measuring with a small margin of error of liters, but it is very close to what the company that supplies it charges me.

@wmarcolin

Great to know that. Did you program that, or use some third-party code?

[wmarcolin]

@akbooer

Third-party code, using Arduino I uploaded the code to program the WiFi on the board, and then installed the drives on Hubitat, very simple and fast.

The part that was a little more complicated was the tuning of the valve, I used another digital meter for the initial reading and then adjusted in a simple way the conversion from pulses to liters that appears in Hubitat.

Finally, I generated the device for the MSR, and then the world of play started, all exported to influxDb and Graphana.
