This is a cool little relay! I used it to automate my pool controls (pump on, valve mode control and waterfall). Super simple to setup and set the time of day schedules. Its been working flawlessly.

I limit the charge current to 10 A 120v home wall outlet to not overload my wall circuit panel. I want to trickle charge my bank of lithium battery’s when the sun don’t shine. This device works well and easy to wire and setup. There is a very nice Shelly app to manually kick on the charge when I feel it’s needed. I can automate the process on a hourly basis or I can learn a bit of programming and logically kick on the charge if the battery’s get low.

I`ve been doing Automation since 2008. As integrator, global cache was our first option but it`s been raising pricing w/o roof.Just tried this Shelly pro DIN on a Elan Home system and it work like a charm. ( need to purchase a $15 third party driver but heck, it`s a premium job)Their web interface is super complete and pro. Wi-Fi setup was a joke in how fast it adapted ( tested 2.4Ghz with WPA2)

The 4PM is used in my attic, managing the attic, bathroom, dryer fans, lights, and environmental sensors. I am using it to see if running the various fans is cost-effective and if the attic fan has any effect on the temperature in the house and the cost of cooling or heating.It was easy to set up and configure; it was quickly discovered by my home automation solution. Din rail makes it easy to put in an enclosure.

These are great. easy to use. Easy to set up. I used mine to replace a swamp cooler controller. It was easy to do and to integrate with Home Assistant.

I really like this product, and look forward to more like it, hopefully Shelly continues to deliver. My biggest gripe is really with respect to the terminal sizing on the unit, and the literature included; it's hard to know ahead of time that the terminals are smaller than what the average US customer might be used to in a residential setting, and these things are really not fit for larger romex conductors, and I've run into scenarios that were a little sketchy when clients jumpered in wire with less ampacity to fit the Shelly relay at hand. Aside from that I'm a fan, just do a deep dive with conductor sizes and ratings and cross against the products!

El producto es de calidad, aunque se siente de un plástico un poco débil. No es tan simple de conectar y no es PM; lo cambie por un modelo shelly 4PM y este resultó mucho mejor y más simple de conectar

Använder Pro 3 tillsammans med ett skript som hämtar elpriset online för att styra (På/Av/blockera) min CTC panna under de dyraste timmarna. Fungerat kanon i ca 1 månad.

Great product, we have four in our control cabinet and use it to get a good understanding how much electricity we are using and where in much more detail than before. Which is nice because it help us reduce a significant amount and gave us good insights how many battery power (off grid home) we need to become fully self sufficient.+ trustworthy and very detailed+ doesn’t require cloud+ easy to install for home assistance

Fungerar som tänkt utan problem. Känns lite lätt och plastig och hade kunnat vara lite kraftigare plintar för kabel. Funktionsmässigt mycket bra.
