And please note these inrush current limiters are basically a resistor with a high resistance when cold and a low resistance when hot.
these do get very hot and need their dedicated enclosure.
i have them for my infrared sauna to limit the starting current in the winter(light bulbs will get lower resistance the colder it gets)
Version 1.11.7 seems to have fixed things.
would be nicve if we have clear changelogs so i could figur this out by reading instead of trying
Hello,
i use a shelly 1PM with factory firmware(also tried v1.9.4)
i use it to switch on a 220-12v ledstrip(10 watt)
when the ledstrip is on a steady color/steady load it nicely reports the internal temperature both when it is switched on and off
However when i let the trip animate(color fades) i notice the temperature freezes and does not change anymore
when switching off it starts reporting again.
power reporting still works
it looks like it can only handle reporting the power and has no time to report/change the temperature anymore
At 17:20 it switches on with animating load
at 20:15 i do a reboot to see if this clears things up
at 21:00 i switch the load to asteady color at 23:15 i switch it off
i checked with mqtt explorer and it just stops with sending out the temperature value. it only updates the power usage
this is the powerload
the new MQTT format is valid for all Gen2 devices: Plus and the Pro series
thanks. so it is save to upgrade the 1pm i guess
Currently i use the 1PM with factory firmware
i have heared that newer shellies(with newer firmware) switched from several mqtt topics to 1 big topic with everything in it.
so from several topics:
shellies/shelly1pm-xxxxxxxx/relay/0
shellies/shelly1pm-xxxxxxxx/relay/0/power
shellies/shelly1pm-xxxxxxxx/relay/0/power/energy
to something like this(did not see the actual string so interpreting)
{
"Relay" : On,
"LastUpdate" : "2021-12-07 17:39:07",
"power" : 8,
"description" : "shelly1pm-xxxxxxxx",
"energy" : 150,
}
fromj what firmware levels will this new stringtype be implemented or is it only implemented with different series like the plus series
Aha. now it makes sense. lucky for me the load is max 20 watts(8 watt most of the time)
Brilliant argumentation! But you ignored Shelly 1PM has an integrated energy metering, which uses a shunt resistor to determine the value of the flowing current. The more current, the more heat…
Hello,
i notice that the shelly1pm is getting warmer when turned on. not much because i have a small load.
However i see people complaining that it is getting hot when a high load is switched, why is that?
if it was using some kind of semiconductor it would make sense but the 1pm is using a relay and that one has very low resistance
Your url don't work, shelly in AP have no internet.
Original factory firmware isn't published by Allterco. Later versions ate in the archiv for first generation devices.
ok thanks, makes sense.
module with default firmware is working very well so fo now i stick with the default firmware. i use it with domoticz so i hate to break functionality when upgrading to v1.11.7
i got a quotestion about this.
with this methode you can not downgrade to the original firmware of the Shelly 1PM
will this command work to install the original firmware again?
http://192.168.33.1/ota?url=http://api.shelly.cloud/firmware/SHSW-PM.zip
also it would be nice to put the original factory firmware in the drop down list to make downgrades idiotproof
thanks
