12awg will, as you know - by code, have a max breaker size of 20A in the US. It's good that they went with a larger relay & CT than the wire rating though. I had dry rotted insulation kill 2 Shelly 1PMs on an outdoor led flood. Wire would arc to ground when the wind blew just right. 1st Shelly survived it tripping the breaker, once; welded the 2nd time. 2nd unit burned open on a 15A circuit breaker. My head wasn't thinking or I'd have checked the 30yr old wiring on the 1st incident. 🤦🏼🤦🏼🤦🏼🤦🏼🤦🏼 I have a 7A glass fuse and new wire on the circuit now. What's odd is the new Shelly started reporting 30% less power draw about a month ago but I can't tell the light output has diminished. Time to break out the current probe.

Not necessarily. A self-contained listed device can use smaller wire gauges if the insulation is rated for the extra heat and the self contained device undergoes certification. Oven manufacturers do this all the time for models sold in the USA. They will use wire gauges that seem way too small but if you read the manual they explain that it has been UL listed and the insulation value is very high and the electrician needs to follow the sizing guide in the manual to determine breaker size and wiring to the appliance and not mimic the small wire gauge seen on the oven's whip. With that said, Here in North America, you are going to have a difficult time finding a load that uses a 25A breaker AND is single phase 120V, which basically will limit you to 20A using this Sonoff device. This Sonoff device was purpose-built and intended for the Indian market where 25A breakers are common, DIN rail circuit breaker mounting is common, and where the electrical is single phase at 230V. Most likely this was intended to control the HVAC unit for a hotel room with a thermostat or occupancy sensor wired in to control the relay. www.indiamart.com/proddetail/legrand-rx3-25a-single-pole-mcb-15004577262.html

Very clever the NC relay. I myself had thought a bunch times to take off the relay of some of mine plugs that have to be always on. Althow the 25A, still feel nervous about all my house power pass to that relay, but i notested that it is very easy to make that not pass at all through the relay nor the pcb. If that was esp32 it was a sure buy, with esp8266 i have to think better 😁

Just letting everyone know… My FTDI with 3.3V didn’t work to flash. At the last try, I changed to 5V and I worked great. Ps: I know it should be 3.3V, but I was desperate and gave it a try, and it worked great. If anyone is experiencing the same problem.
@digiblurDIY Жыл бұрын
FTDI is known to not have enough power in many cases. Usually those involve an ESP32 which is surprising yours didn't work here on the esp8266. I usually do not recommend the 5V thing as people have fried their chips before with this.

Still no cable clamp... so the big device still has to be mounted inside an even bigger box with some way to prevent the cables being yanked out
@GregWoodsLancs2 жыл бұрын
I can't understand why they added those big beefy cables just to move the connection point a few inches towards the outside edge of the box. A better design (at least one more compatible with the UK) would be to have the installer open the box, attach all 4 wires inside the box to the those beefy connectors near the relay, and then there is room for 2x clamps around the outer insulated cables. And where are the earth connectors? Just because the device doesn't use it, they must still be connected together. At least the POW R2 had connectors for earth. So while I initially liked the look of this device, it still needs a custom enclosure to be safe. Shame

I was thinking about getting the POW R3 for my pool pump. It's 115 volt, 1ph, 12.0/3.1 amp (don't know what 3.1 means). The unit looks substantial. I was wondering what the Tasmota user interface looks like. Does it graph your energy usage... Daily, weekly, monthly? Can you download the data? Schedule On, Off times? Have it automatically turn off at a specific current? Does it actually show amps, volts and watts? Thanks

Correct me if I'm wrong, but the device switches only one phase, so this won't work for switching a US water heater right? The water heater in my house uses 2 phases. I sent Sonoff an email asking if this would work for that purpose, and they said yes. Can someone confirm?
@digiblurDIY2 жыл бұрын
Correct this only one relay for one single phase. The US electrical water heater is usually 240v out of the split phase to the home so you have two hots to cut. In this case I would probably go with a contactor that can cut both hot wires.
@mikepeterson4432 жыл бұрын
@@digiblurDIY Thanks. I'm guessing in Asia, one relay is all it takes to switch a single phase, 240VAC. Good suggestion on using a contactor. So a 2 pole contactor, 120V coil and a plastic housing to throw both in, I should have a decently priced wifi water heater switch. Actually, if I'm going to use a contactor, I wouldn't need the POWR3 to energize the contactor right? I could just use, say a Sonoff Mini for that purpose?

Yes. You would only lack power monitoring at that point. Sonoff Basic works as well. Depending on the type of contactor and it's input requirements.

@@digiblurDIY Not sure if the POWR3 would be useful in this case for monitoring the power because the two hots would go directly into the contactor, the POWR3 would be just drawing whatever current it takes to energize the contactor, and not seeing the current drawn by the water heater. Am I wrong?
