Here is a sample Shelly 1PM entities list:
As you can see, current or voltage are not available.
I flashed shelly1pm with sonoff tasmota.i think it works fine.
I have connected CF1 to GPIO14 and SEL to GPIO12.
What would be the correct configuration? I think mA may have started working but not voltage…
@alferboy I have since replaced my 1pm’s with 2.5’s, which have a different sensor. So I am not setup to test this, but referring to the esphome docs it appears my originally posted config above may be incorrect… Try using the config posted on the info page instead:
sensor:
- platform: hlw8012
sel_pin: 5
cf_pin: 14
cf1_pin: 13
current:
name: "HLW8012 Current"
voltage:
name: "HLW8012 Voltage"
power:
name: "HLW8012 Power"
energy:
name: "HLW8012 Energy"
update_interval: 60s
Also note at the bottom of the page there is a section about a “Permanent SEL Pin” hardware variant, which only has measurement mode available (likely power only). I suppose if you have a 1pm that has the pullup, you could find out how to remove it from the board to allow all 3 measurement modes.
That was my base to add current and voltage, but according to the pins used as in https://github.com/arendst/Tasmota/issues/5716 (GPIO12 and GPIO14). There is no pull-up a.
I’ve connected those wires but it seems maybe something’s mixed up on the voltage/current (they seem maybe “swapped”).
With a 4w led bulb I was getting:

When voltage is belows 100v is when I turn off the relay. Yet current is always fixed, leading me to believe that they are somehow exchanged. Perhaps the sel pin needs invertion? very odd…
Reading that, my understanding is that the 1pm has some disconnected pins. It looks like Vorta came up with a hack that requires soldering 2 wires on the esp chip. That could be translated to esphome configs easily, but would still require the soldering.
Now, the “proof”:
Consider the “sent watts” as correct (they are pretty close).
Look at when I change the 4w bulb for a 2000w heater…
Takes a few seconds for the value to raise but when it does the “current” stays the same, and the “voltage” increases.
I think the “sel” pin needs inversion. I see no option for that…

I did that soldering, that’s the issue. I soldered the wires as suggested.
cf1_pin: GPIO14
sel_pin: GPIO12
And it does get current/voltage values.
Yet, they show up as you see, seemingly swapped.
Does anyone know if this fire hazard issue related to the ade7953 in the shelly 2.5 Shelly 2.5 + ESPHome: potential fire hazard + fix | Savjee.be is all present in the Shelly 1PM and if so if the same fix applies?
To my understanding they have different chips in them. Also my ESPHome flashed shelly 1PM and same with original Shelly FW seem to be running at the same temperature (~50 degrees).
Are you having heat issues with 1PM?
Awesome, like that and while I was able to find a working config here, I always start looking at https://www.esphome-devices.com/ first.
Now I have two questions, is esphome-devices not good to start over or why do these configs not end up on that website?
Is there anything better to get things rolling with esphome and a “working” config?
I am thinking about Tasmota Device Templates Repository - Templates for Tasmota which is THE go to site for getting devices up and running with Tasmota. Lots of people buy devices because the show up there with a configuration.
Thanks for the 1PM config anyhow.
Because no one takes the time to do so… I did a few and it takes some time to do so.
Here’s my config I compiled from a few sources I found here and there. What’s added:
- restart switch
- wifi signal sensor
- polynomial calibration which works for me much better than linear calibration
- total daily energy sensor
- overheat protection with notification

I’m sorry for not posting the config there, but it’s not really easy to do so and I can’t easily figure it out with time limitations on my hands.

Awesome, thanks for sharing your findings regarding calibration! I suspected linear was going to be a bit off… kinda surprised it lines up with 5th/6th order, but then I know nothing about the sensor.
Is anyone using this with a light switch and have it working where the relay in the shelly “follows” the switch? For example, if you turn the light or whatever it is controlling on using HA, obviously the physical switch would still be in the off position. Then if you flip the physical switch to the on position, nothing would happen until you move the physical switch to the off position. I know it might seem petty, but I like for my smart relays to follow my physical switches. I don’t want the physical switch to just be a toggle.
I tried to convert one of my shelly1PM to esphome starting with mgos2tasmota OTA. It was powered with 230v. Looking at the log, it downloaded the tasmota firmware. Then it went offline and never came back. It took it out and have been trying to get a serial connection with no luck. I use a PL2303 USB to serial thing, booting with GPIO0 grounded and not. I’ve tried TX/RX both ways using 5 different softwares with no luck. Could the ESP chip have been fried because of the alternative firmware?
EDIT: I tried esptool, and for some reason it managed to connect and flash. Problem solved.
Has anyone succeeded with the temperature sensor addon? I tried GitHub - persuader72/esphome-components: Custom esphome components but it won’t work.
This part should solve your problem. Just comment out the toggle part and uncomment the rest. Let me know if it works. Thanks!
Hi I just wanted to bump this thread.
I converted over my Shelly 2.5s to ESP Home out of frustration with the MQTT auto-discovery script and the inability to easily create a device in YAML rather than creating single entities not tied together in 1 device (yes I know attributes exist but it’s just not the same as a device).
Anyway after setting the config file to just the way I like I realised the power monitoring is wildly off. Scavenging off forum threads this is the best config I can make.
Does anyone have suggestions on how to make the power monitoring more accurate for Shelly 2.5’s? I’m using linear calibration, I actually had worse results with polynomial 2 and 3 degree’s (I haven’t tried 5 degrees) I’m thinking of just disabling the sensors at this rate as I have whole home power monitoring.

When doing polynomial calibration, it’s worth checking the result with a spreadsheet. I don’t know if they use the same curve fitting algorithms as esphome, but it might receal some surprising results.
