So basically this forum does not only have a horrible layout with flashing ads but is also not useful?

Listen, dont let the ultratards from marketing destroy your brand.

To get actual power of all 3 phases:

I am actually using "http://" + Shelly_IP + "/status"

or

"http://" + Shelly_IP + "/emeter/0" for each of the 3 emeter.

First method use massive overhead to get one simple signed value.

Second method needs 3 http requests. Is there a better way?

I want "http://" + Shelly_IP + "/aPower" and i want it every second. Is this possible?

>Shelly EM

Yep, at more than double the price.

A 300W solar grid tie inverter costs $50

The split-core EM costs $35 per inverter, the 2.5 only $13

Guess i will slaughter the 2.5, remove the relay's and solder in bridges.

Alternatively we could convince the developers to pwm the relais. After full power to activate reduce power to 1/3 to keep them activated. I hope they have a flyback diode over the coil already? Just a firmware change, the esp8266 can do pwm nicely.

Shelly 2.5 gets pretty warm with 700W constant load, 350W each channel.

Does the heat come from the measuring shunt or from the "always on" relay?

Should i bridge the relay since i do not really need it?

I use it for monitoring the two solar micro-grid-tie inverter.

I have a water heat pump on phase 3. It consumes 500W with power factor of 0.8 inductive. A 1uf capacitor over phase3 should correct the power factor. I can switch the cap in with the em3 relay.

There is no message "power factor bad" from the shelly, so i might use "power over 400W" to switch the relay since there is not other big load on the phase.

Good idea or not?
