No spam, no selling your details, just notifications when I publish a new blog! Do you have other awesome automations or cool setups? Power to the Shelly and the light switch, along with ground and neutral come from the second wall switch. 273 And if I do, I'll update this post or tweet about it. Instead of using a standard electrical circuit, millivolt systems use a thermocouple/thermopile (powered by the pilot light) to generate enough electrical voltage to open the gas valve. Follow the official Shelly instructions and use a qualified electrician. If so you can also consider using something like the Bond RF controller or the Sonoff RF Bridge to add remote control. Once I'm awake, I'll get out of bed. Overall, Im pretty happy with this project. These are just my own views. The thicker red wire sticking out the Shelly is the load wire that will connect to the wall switch. /ColorSpace /DeviceRGB After publishing this blog post, a reader reached out with a solution: replace the sensors cap with a custom designed one: You can download the STL file for it here. Have a look at the /CA 1.0 So I've installed the Shelly EM to be powered by a standard plug: Before installing the Shelly in situ, I powered up the device so that I could use the Shelly app to connect the device to my network ahead of time. >> Because the built-in version only supports digital inputs, not analog ones. This website uses cookies to improve your experience while you navigate through the website. I do have an outlet there, but it is NOT easily accessible. The availability_topic tells Home Assistant whether or not the Shelly is online, and is also updated by the Shelly. While the regular version is cheaper, it does not have this insulation. It would also get stuck in a loop when the mirror stopped in front of the sensor. After connecting, go to the IP address 192.168.33.1. My gas meter is an Elster BK-G4M, a model that is quite common in Belgium. To find out, I added a utility meter to Home Assistant: I then set the value of this utility meter to the value of my actual gas meter by calling the utility_meter.calibrate service: After two weeks, I compared the virtual utility meter with my actual one. Although I've mainly used Shelly devices for automating lighting, they produce other devices such as an Energy Monitory (Shelly EM). +60VDC Voltage & Current & Power & Temperature, Moisture & Temperature & Humidity & Light. Fitting a smart switch and a relay in the small box and keeping the mains voltage lines clearly apart from the lines that control the fireplace seems difficult. They cost around 50, which I found expensive given that this is just a reed contact that reacts to the magnet inside the meter. $4%&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz ? Once again Ive found a great use for the inexpensive Shelly relay. 1 0 obj First, the offset you will need to use is the number of hours since epoch. But more on that later! In 2019, I built an energy monitor to keep track of our electricity consumption. Under Server: enter the IP address of your MQTT broker along with its port (usually 1883). Click the checkmark to Enable action execution via MQTT (note this will disable cloud access. You need to be able to power the Shelly, and you need a neutral. /SM 0.02 One thing I want to make sure of is that you use the Shelly 1 for this. The theory says we should do the former, but now I can test this in the real world. I've written previously about how I've used Shelly's to make my existing light, Last year I made my own Raspberry PI powered LED strip for the desk in my home Okay, I'm measuring gas usage. office All needed voltage comes from the thermocouple and/or thermopile. If you dont have this at the switch, you can install the Shelly underneath the fireplace, but you need to be able to supply power there. This effectively turns your fireplace on.. Or you can add the following automation: Sending announce to the shellies/command topic tells all Shelly relays on your network to send an updated message to the Will Topic, allowing Home Assistant to see that they are available. This was caused by infrared light being reflected by the glass cover of my meter. [/Pattern /DeviceRGB] Using a smart appliance module and a relay will only work if I have an outlet easily accessible in or near the fireplace housing. Elster sells a reed contact that is specifically designed to be mounted onto these meters. /Filter /DCTDecode As a result, a Shelly EM can typically be used to monitor the power consumption of an individual circuit or the power draw of an entire house. It's insulated to conform to older standards and is nowhere near efficient in today's standards. On the left, it looks like they used thermostat wiring to connect up to the thermocouple (red and white wires). /Length 9 0 R But in the end, everything worked out, and the sensor has been working reliably for the last 2 weeks. /Filter /FlateDecode # sometimes rapidly switches from ON to OFF, causing a lot of "ghost" pulses. In my case, I just want to monitor a single feed as you can see in the picture above. All that's left now is to design and 3D print a case to protect the microcontroller from the "harsh" and dusty conditions in my basement. I tried repositioning the reed switch, but to no avail. The output voltage is around 0.25V when the mirror is not facing the sensor, and when it is, the voltage drops to 0.18V. You just need to add a little YAML to your Home Assistant configuration in your switch section: Replace the xxxxxx in the topics with the ID of the Shelly you noted in the web interface will topic. ), and Ive had a lot of success using it as a light switch and to control my garage doors. As a result, I'm the Technically, all ESP8266/ESP32 devices are supported by ESPHome. So use Epoch Converter or some other tool to get the epoch seconds at the point in time you introduce this sensor and divide that by 3600 to give you the number of hours since the epoch. This little cap makes sure that the infrared light stays separated from the sensor until it hits my meters glass cover. However, this is mitigated by having the energy sensor increment by 1Wh every hour, which is the smallest possible unit and overall will have a negligible impact on your actual energy consumption. Sensors have been split into categories. No mains voltage should enter this system. [https://www.jamesridgway.co.uk/using-a-raspberry-pi-to-make-my-office-desk-glow/] Youll need this to create the Home Assistant config. 1 2 . In my sensors.yaml file I have created the following sensor. If so, are you interested in supporting me and this site? >> Creating a smart fireplace switch is something I have been interested in for a long time. I considered the following options: I quickly ruled out the first 3 options because: That leaves me with a Z-wave relay and the Shelly 1. At the time I'm writing this post, there is an open feature request for supporting a standing charge Energy: Add fixed daily cost. A thermopile can supply more voltage (up to around 900 millivolts) in case you want to also power a thermostat. Alexa Guard Overview & Integration w/Home Assistant, Smart Home Dimming with The Shelly Dimmer 2, MQTT With Home Assistant Using Docker & Mosquitto. 4 0 obj Go to the Internet & Security->Advanced Developer Settings and: Take note of the Will Topic. This is the MQTT topic that communicates whether or not the Shelly is up and running. After turning the power on, I configured the Shelly, which is the next step. I just want you to be careful. /ColorSpace /DeviceRGB Shelly Plus 1 Review: Better Than the Original? :YrH4W% ^>%GmGw{pggSHvUx($%%}:|}k0 ig;zluM_Wz7 #s_e qfce64Ju$M6E=f5X]OsmjO4(^8PD*n{sg-PqA:tsk6>yumhjQ6{Vh$`gi&t60|X V0XX5{e+IYV!
