Updated 2024-11-09 I have been using Shelly devices for quite some time both on our boat , off grid, and also as HomeKit (HK) accessories via Homebridge (HB) .  I was really amazed when I found that some smart guys have created a software package that replaces the stock, official, Shelly firmware with the  "Shelly-HomeKit" package which emulates a "native"  Apple HomeKit accessory. It's very nice done, really simple, and the flashing of the software is done over the air (OTA) with your ordinary WEB-browser.

Updated 2023-05-03 ! In a  former post I made a writing about Shelly 1 (S1) and this post will handle about the successor Shelly PLUS 1 (SP1)  but much of the content is also valid for some of  Shellys other devices  which uses the same software/API. To keep it simple, SP1 is a WiFi switch, 16 Amps, with dry contacts but compared to the S1 the hardware and the software is updated.  The function "without Internet" + that the SP1 can use a 12V DC source makes it perfect for an "use case" i n a boat/mobile home .

Updated 2023-05-04 ! This post focus on  Shelly 1 (S1), a really a nice automation device with great versatility, but much of the content is also valid for some of  Shellys other devices  using the gen1 API. Setup for the later version,  Shelly Plus 1 , is found here  !! S1 is a WiFi switch, 16 Amps, with dry contacts and t he function "without Internet" + that the S1 can use a 12V DC source makes it perfect for an "use case" in a  boat /mobile home. It's compatible with Alexa , Google  or HomeKit using HomeBridge  or as a "native" HomeKit device using  Mongoose firmware (Flashed via a standard WEB browser !)

Updated 2023-05-01 ! I really recommend flashing, via WEB-browser, the device with Mongoose software to avoid Homebridge.   HomeBridge is used for this setup and to make it appear in the Apple Home app. The main advantage with the Shelly devices are that they are WiFi enabled and therefore You don't have to use a hub, this compared to z-way/zigbee and some other solutions.  First install Shelly1 (S1).

Updated 2021-03-13 ! Here I'm trying to do the "ultimate" SignalK switch blog post including( no N2K) Shelly 1 as the hardware switch NodeRed as the function engine NodeRed dashboard as input/output interface WilhelmSK as input/output, check picture A http endpoint as state sensing The post is ment to be a template where you can pick the parts which are right for your setup.

Matter is a smart home standard currently being developed by a consortium of over two hundred companies, including big players such as   Apple ,   Google ,   Phillips ,   Amazon   and   Samsung . Many new devices have Matter implemented, from the beginning, but devices, such as most of Shelly devices don't. On the other hand many hubs can be upgraded to Matter support. For example an Apple TV. With a Matter bridge  you can solve the incompability. This post will use  Matter bridge plugin Manager and the Shelly plugin  but it could be other devices shown in the picture below.

In this post I will give some thoughts, high level, and methods for matching the hourly prices from your energy supplier. I will also list some gadgets and by using NodeRed ,  get the data, visualize it and control the consumption. So in that perspective there are some needed prerequisites.....

An introduction to the SignalK(SK), Marine application, is given  here . A very easy way to measure temperatures with SK is to use one wire (1W)  DS18B20  (DS)temperature sensors.  In a former post the DS:s where connected direkt to the RPi GPIO:s, but in this post they are WiFi enabled via the Shelly 1 (S1). Alarms are also sent when the temperature exceeds a set value. If humidity is of interest You can use a   DHT22  sensor instead of a DS sensor.

I have made several posts regarding temperature ,  in some way, and now I'm back with a post using Home Assistant(HA) and controlling temperature. The primary purpose of this post is to address an upcoming issue with our floor heating system. However, it may also provide some assistance for other temperature control problems using HA "Generic Thermostat" As said before I'm more comfortable with Node-RED then YAML, in HA, so .....😎 My latest and most sophisticated heating control solution is found here !!

The electrical install instructions for the Ring Doorbell maybe could be a little easier to find  ?  So will give some links where you are connecting to Internal doorbells No internal doorbell but charging the battery External relay, triggering "anything" Wireless relay Ring Device manuals are found here .

Updated 2023-11-06 ! I have searched for a solution transmitting the NMEA data, from the navigation network, via WiFi, to for example  iSailor  or other Tablet/Phone applications. Most of these applications just accepts NMEA0183(N1) but many boats are also using SeaTalk 1(ST1) and NMEA2000(N2K). This post will cover, kept compact, my best findings covering both a DIY and a commercial approach to handle the different protocols.

I have tried to find some basics how a standard underfloor control system is regulating the heating, but haven't, so started with checking up  our own temperature control system from LK (TCS). I used Node-Red, with Raspberry Pi(RPi), sensing when the TCS applied voltage to the actuator. Since the actuator is running on 24 VAC and the input on a GPIO PIN is maximum 3,3 VDC I used a optocoupler to level shift.  Schematics below Please find another post here where I realized, using Shelly 1 and NodeRed , the regulating of the underfloor !!

In previous posts , I’ve been testing and figuring out how to manage my old control system for our underfloor heating. Now, it was time for something more bold, and since I’m increasingly impressed with Home Assistant(HA) and its software capabilities, that’s exactly what I did. Industrial-style ESP32 boards are becoming increasingly popular for Home Assistant and automation projects, especially when they include Ethernet, isolated inputs and relay outputs on a single PCB. The Waveshare ESP32-S3-ETH-8DI-8RO (W8) is one such board: it’s compact, well-equipped and clearly designed for serious control applications, rather than just hobbyist breadboards. In this post, I’ll share my experience setting up this board using ESPHome , pointing out the main configuration points, common mistakes and practical lessons I’ve learned along the way.

Updated 2026-01-03 ! In a former post I did some hacking/checking how our underfloor heating control system handled the valves, via actuators, regulating the heat.  Now it was time to do some tests with Node-RED(NR), with a PID controller ,  and a Shelly 1 (S1) connected via WiFi and driving the actuator. I really nice solution with Home Assistant and a relay board is found here !
