Capacitive - / inductive + which means effective power without reactive power amount... so if you need for example 1000W power to do work and PF is -0.7 or +0.7 then you actually need over 1400W worth of Amperes through wiring but only 1000W does work. cos φ = P / S = P / (U·I) Negative value means you make the extra from devices to grid, compensating the positive at grid side. Other way you need to transfer that from grid. Amount is same, direction isn't. Compensation should be at close as possible to devices needing it. That's why power factor correction.

Hi! I think that should fit. There's plenty of free space inside. The relays from factory are 20A mini relays (sub miniatyre high power version), so bigger than in other Shelly devices. I think those were Hongfa HF25F type...

Turn MQTT on and RPC event messages ("RPC status notifications over MQTT:")on from it. It will send info to MQTT broker, including all that and more. {"src":"shellypro3em-##########","dst":"#########/events","method":"NotifyStatus","params":{"ts":1714929935.58,"em:0":{"id":0,"a_act_power":216.2,"a_aprt_power":297.5,"a_current":1.268,"a_freq":50.0,"a_pf":0.72,"a_voltage":234.9,"b_act_power":-20.5,"b_aprt_power":65.3,"b_current":0.276,"b_freq":50.0,"b_pf":0.31,"b_voltage":236.8,"c_act_power":46.7,"c_aprt_power":185.8,"c_current":0.786,"c_freq":50.0,"c_pf":0.27,"c_voltage":236.7,"n_current":null,"total_act_power":242.430,"total_aprt_power":548.652,"total_current":2.330}}} There you find all the values like a_current b_current and c_current

1/2; this is official, but also end-user to end-user, and 1/2, not 3; this forum you may find answers, but if not then use 2 which is only official real support system, that 3 is just 3rd party's thing nothing to do with official things

Do you route N through device terminals? It's common cause...

Like already told, you need dry relay between those if the supposed to be triggering one leaks voltage. If any voltage difference, it will trigger Shelly SW input. There's about half of voltage at input with small energy (partial wave), so it will trigger to any difference (to L or to N or something else if leaks to different potential).

Which version of Plug S, the old Gen1 or Plus v1/v2? After firmware update be sure you have refreshed cache of browser. The program is running partially at browser and old cache will keep old program parts in memory. CTRL-F5 or so.

Plus devices have 500mA fuse and VDR to catch real power surges. Used here with constant 220-240Vac 50Hz.

Great! Thank you for info. Many are waiting to have that solved.

The technology is called 1-wire. You can feed these from any DC source locally and just transfer data by one wire, another one has to be same ground but not exactly in same cable.

Did you already figure out it? This is way to turn on/off relays (in example first one, starts from 0) mosquitto_pub -u "$user" -P "$pass" -h localhost -t "$id"/rpc -m '{"id": 1, "src": "whatever", "method":"Switch.Set", "params":{"id":0,"on":true} }' mosquitto_pub -u "$user" -P "$pass" -h localhost -t "$id"/rpc -m '{"id": 1, "src": "justsomething", "method":"Switch.Set", "params":{"id":0,"on":false} }' same with all gen2 except switch-addon to Pro 3EM which is relay 100. So like this mosquitto_pub -h 10.200.0.8 -u user -P pass -p 1883 -t shellyplus1pm-7c87ce735d94/rpc -m '{"id": 123, "src": "whocares", "method":"Switch.Set", "params":{"id":0,"on":true} }'

I can confirm, same happens. Some amount of debug log just disappears somewhere after running that? Same with UDP log etc...

Some of my clients and -teme- from this forum (when testing) have had also some similiar things happening... It's possibly reason of lack of some filtering of data, when there's some times peak values as kind of status code from recently restarted 1-wire DS18B20 or so... another possibility is some issues with most new batches of DS18B20. How ever error values should be allowed to be filtered out if not automatically done. Edit: Forgot to tell, that if I haven't got it wrong, it's under inspection to do fix at Shelly (?)

TRV's have such a old firmware that those should be updated at first stage of installation. Then all go nicely...

I found yesterday the button was somehow wrong position and then found the face cover was separated from body after being couple of days with me in bag. It also happened to make loose contact and dry battery.
