Zitat von Janos Becsi

I've tried with 3V rechargable cr123A (RCR123A -3,0V -500mAh/1,5Wh -Li-Fe) and also cooked it. Smoke came from the unit. The temperature sensor measured 48°C. It worked for couple of hours, the temperature came down to 36°C, but after that it stopped. The batteries were also warm. I will recharge the batteries and measure the voltage.

make sure that the batteries are 3v. if they are the correct batteries check that you put them in the correct position. it is strange that the device has gone up in smoke

hello:

In H.A. you can use the utility metter integration.

With utility metter you can read the values of the Shelly EM device, with those values you can create different hourly, daily, weekly, quarterly and yearly energy meters. all of them with different rates. It can be adjusted to the billing period of your electric bill.

I use it to see my electric bill from day to day.

I forgot, you can reset it anytime you want.

I've had the same problem. I have solved it by buying in aliexpress a charger and 4 rechargeable lithium batteries cr123a 3v. it is very important that they are 3 volts.

In a shelly door and windows lasts approximately 4 months. the negative point is that when they are discharged they go from 100% to turn off the device in just 3 days, but for that I already have two batteries loaded with replacement.

I have lengthened the cables of the temperature sensor approximately 20 meters.

I have used a 3-wire, 0.5 mm electric hose.

It works properly.

the intensity relation in three-phase current is √3

8.53 kWh + 9.01 kWh+ 5.79 kWh = 23,33kWh

23,33kWh / √3 = 13,48 kWh

calculating the average intensity

8.53 kWh + 9.01 kWh+ 5.79 kWh = 23,33kWh

23,33kWh / 3 = 7,77kWh

7,77kWh * √3 =13,45kWh

remember that you have to cut current, give current. in less than 1 minute you turn on and off 5 times.

They have a physical button that if you press it, it resets.

I don't remember if you have to hold down the button for some time

Saludos

I have performed a check with my EM devices.

If the clamp has cable nearby. At the time it passes current by the cable, the clamp starts showing a small measure.

It is possible that the clamp is near a circuit that has load and this generates induction giving the value you read in the circuit without load.

You can put a long cable to keep the clamp away and try if there is reading in this way

I have had the same problem on a shelly dimmer 2.

the product is defective.

Sounds like one of the two mosfets that drive the output is shorted, this will cause only one half of the AC waveform to be switched.

I have opened a ticket and received a replacement

100 a is too much for a house you should check that data.

I got a new one from me supplier.

hello I have mounted a shelly dimmer 2 with a similar problem, it only worked for a few minutes, then it turned off.
I opened a ticket to shelly and after several tests they made me a replacement.
I received a new unit and it also had a problem, it did not turn off the light, it was always on.
It has also been replaced, on this occasion I will ask for another model.

hello Hubeetomi

I solved the problem with new batteries, the bad thing is that they lasted a short time and the problem returned in 2 months when they lost charge. When putting the rechargeable batteries I have the problem solved since when they lose charge I will recharge them.

It would be interesting that if you have a voltmeter you measure the voltage of the batteries and post its value

I use a trick to wake up the shelly dimmer 2. It is the opening and closing the door several times at the same time that I start communication.

I have also had the problem of the batteries, they lasted me more than 2 months.

The solution has been to put some rechargeable batteries that I bought in aliexpress, 4 rechargeable batteries and the charger cost me the same as the 2 batteries.

I have put the rechargeable batteries 2 months ago and they continue at 100%.

Shelly dimer 2 has the problem that it stops working when the batteries are at 80%. With rechargeable batteries I don't know at what percentage they will stop working

shelly dimmer 2 won't turn off.

I have installed shelly dimmer 2, when I turn it off it stays on at approximately 50%. The application shows that it is off.

When it is in off mode the bulb remains on at 50% also it blinks rapidly. If I increase the power it stops blinking.

I have tried with the factory firm and I have updated to the latest version. I have used incandescent bulb and dimmable led bulb with the same result

hi have you had a similar problem with a shelly dimmer 2.

the shelly dimmer 2 appeared in the app for only 2 minutes.

then it disappeared.

to work again I had to wait and plug it in again. After 2 minutes it turned off again.

It only worked for about 2 minutes.

shelly suport has replaced him

I have had this problem on a door and windows 2.

the batteries were at 80%, shortly after I lost the connection.

I have solved it with new batteries

flip the coil over, or put it on the other induction cooker wire.
