Breathing fresh air because of my Shelly smart relay
I was able to configure the Shelly 1 Gen4 to work with my whole house ventilator. After purchasing a air quality monitor I noticed VOCs and CO2 numbers getting very high at times. CO2 was getting very high at night went I slept with the bedroom door closed. I noticed I would wake up in the middle of the night when co2 peaked in the room. I Purchased the Shelly 1 Gen4 to control my home ventilator. In Apple Home I have a schedule that turns the vent on every night when I go to bed. When I get some time I am going to connect the Shelly and my Airthings air quality monitor so that when co2 or VOC goes above a specific threshold it starts the house ventilator. This type of automation is totally possible with this device.

Fun Sprinkler Hack with Shelly 1 Gen4
I used the Shelly 1 Gen4 as a master switch for my dumb sprinkler controller. I had a smart sprinkler controller in the past, but I never really used all the extra features those companies advertise. My sprinkler schedule is fixed, but I still wanted the option to turn it on and off remotely.Fortunately, my sprinkler controller has a rain sensor connection, which I connected to the Shelly 1. This lets me simulate rain by toggling the Shellyâs relay. I also used the SW (in detached mode) to monitor how long the sprinkler is runningâthough it only tracks one zone.I like this setup because it keeps things simple while still giving me remote control and monitoring. I also trust Shellyâs cloud more than some of the other platforms out there. This is my second Shelly 1 unit, and Iâve been happy with both so far.

So far so good!
Purchased to use with my 12V solar system. The Wifi is able to connect from about 100ft away. Very reliable so far. Phone app works great. I am able to run my fountain from sunrise to sunset.

Easy to set up
Easy to setup if you use the Bluetooth option. Had to use add-on module for garage door open or close indication with magnetic switch.

Excellent product, easy to set up and versatile. Used in conjunction with a contactor for an immersion heater as I didnât want all that current going through the Shelly.

Ich habe mir die Shelly zusammen mit dem Shelly Addon, Magnetschalter und Temeratur Luftfeuchtigkeitssensor gekauft um meine Gargentore zu prüfen. Anleitungen dazu wie dieses umgesetzt werden kann gibt es bei Youtube. Die Hardware sowie die Software von Shelly sind ausgereifte Produkte.
