Esphome and Blitzwolf SHP5?

ESPHome
21

Hi again.
Did anybody found out right config for ESPHome to this plug?

Best,
chrisjan

Pretty easy to figure out from the tasmota config.

23

The one from @depen ( Esphome and Blitzwolf SHP5? ) here above in the thread works.

24

I just setup the device and have the exact same problem.
Voltage is always around 120V instead of 240V and Watt is also halvedā€¦
Setup sensor filter to multiply by 2

The issue with the too low readings of voltage and power is that esphome assumes that the devices use the default setup of voltage divider resistor and current resistor.

The default is 1M Ohm for voltage divider. The 2xx Volt variants of the SPH5 and Gosund SP112 are using 1906 kOhm. You can configure those values for other power meassurement chips but not the CSE7766. (also see: https://github.com/esphome/feature-requests/issues/736)

In theory it should be ā€œmultiply by 1.906ā€ . With 2 you will get values too high.

Hey, I was going to use @depen config from above for my Gosund 112, but it turns out Iā€™ve got Version 3.4 (https://templates.blakadder.com/gosund_SP112_v3_4.html).

Iā€™ve got it somehow working, but before I can calibrate it I need values for:

    current_resistor: ???
    voltage_divider: ???
27

So I did it myself and calibrated the values for current_resistorand voltage_divider with another power meter.

Here is my config and hope it will help someone later:

Does this also measure the consumption of the USB ports?

29

It only has 1 general consumption indicator

Ok, so if i connect something in the USB ports it will show the consumption, right?

31

Not sure. Based on the information in the link below, it would seem that the USB power consumption is not measured: https://github.com/arendst/Tasmota/issues/5756#issuecomment-500026002

Hello all,

I have the same SHP5 plug and because i just do not know, i have to solder and upload a Tasmota firmware in order to have it in HA or can be done with other way?
Thank you in advance for your help.

33

Hi!

I just tried this config but for me no sensing works at all. Did you experience this too?
Voltage, Daily, Power and Current all stay at 0. Switches and RSSI works.

EDIT:
Figured it out. Your setup works on the newer style with different sensor. changed up the code a little to use the old sensor and all working now!

35

@ GravitySandwich: Can you share config? My Voltage and Power is also 0. What did you change?
