I am wondering if it is possible to buy the smaller 50A CT clamps and connect them to the Shell 3em -- mine was supplied with the 120A ones which are too big to fit into my fusebox and I have max 25 A per phase. Are there even smaller compatible clamps?
I am located in the Czech Republic, but I guess any EU source would be fine.
Thanks!
Hi
I don't have much room in my fuse box -- I would like to install a second 3em to monitor a few circuits when the currents will not likely exceed 15A. Are the 50A clamps physically smaller than the 120A ones and therefore worth getting to facilitate the installation?
I guess the problem is that it connects to the extender when my router is offline and then it must be giving up since the extender cannot route without the router, not provide an IP. All my IPs are fixed as are the channels, so that’s not it.
The only way I can switch off the 3em at the circuit breaker is to flip the master breaker — so that won’t help since the router will also reboot. Maybe this is bad wiring, but the manual did not propose anything else.
I just find it extremely annoying that I can retain seemingly all the information at the reset apart from the usage data, which seems like the only information worth protecting.
Hi
Every time my wifi router reboots, my Shelly 3em loses the connection. How am I supposed to get it back on the network?
The only thing I know how to do is to hold the green LED for 10 seconds, which resets Shelly. The settings are saved, so I can reconnect easily, but this process resets all the energy meters in the 3em. In my Home Assistant all the accumulated energy sensors go back to zero.
Surely, there must be some other way of reconnecting without a reset of the meters?
Hi,
I've just connected a (second) shelly 3em to monitor only some circuits in my house (the first measures the total energy consumed at the grid connector).
2 of the three circuits are connected to monitor my induction cooker stove. They are showing a strange behaviour:
* When the stove is on, the power consumption is roughly correct, according to what the total consumption Shelly sees. This consumption positive.
* When the stove is off, there appears to be a small stand-by power use (around 2W), which presumably is correct, but this is reported as negative.
What could this be caused by? I do not have much space in the fuse box, so the clamps have been arranged quite tightly, but they go round only those wires which they are supposed to go round. But maybe there is some interference which becomes apparent at the low currents? What should I check?
