supplement with your own idx at the top of the script


Then create a hardware device: http-poller
Fill as follows

Thanks for the reply to this issue...

Everything is working; Phone APP and Browser.

Why is it suddenly not reading?

Greetings,

Make an issue on the GitHub repository of the plugin https://github.com/Eraser3/HomeWizard-Wifi-p1-plugin

Why is it suddenly not reading?

Ah, got it, you are using a plugin, I cannot awnser that.

The method I described is using the built-in http poller.

A hint: blur your unique ids.

Thanks for the tip

Sorry for the extreme late response. There was a problem with the plugin some time ago and I updated the script back then. It had to do with a firmware update of the p1 meter. I never saw your topic post about this so that's why I never responded to it.

The latest plugin on Github should work fine with the latest updates from HomeWizard.

After 2 weeks I' am getting this error?'

How to debug this issue?

Thanks for youre time to responce

Im also getting this issue, any solution for this?
Im on firmware 5.05

Did my own lua script and renamed the values i wanted.
Seems like i have other values than the script you guys have.

------ BEGIN ------
-- Read API values
s = request['content'];

--
-- Energimeter
--
-- return value
local a = domoticz_applyJsonPath(s,'.total_power_import_t1_kwh')
-- active current return
local b = domoticz_applyJsonPath(s,'.active_power_w')
local c = domoticz_applyJsonPath(s,'active_power_l1_w')
local c = domoticz_applyJsonPath(s,'.active_current_l1_a')
local d = domoticz_applyJsonPath(s,'.active_current_l2_a')
local e = domoticz_applyJsonPath(s,'.active_current_l3_a')
local f = domoticz_applyJsonPath(s,'.active_power_l1_w')
local g = domoticz_applyJsonPath(s,'.active_power_l2_w')
local h = domoticz_applyJsonPath(s,'.active_power_l3_w')
local i = domoticz_applyJsonPath(s,'.wifi_strength')

local idkWh = 7
domoticz_updateDevice(idkWh,'',a*1000)

local idW = 92
domoticz_updateDevice(idW,'',b)

local idA = 98
domoticz_updateDevice(idA,'',c ..";"..d ..";"..e)

local idWiFi = 99
domoticz_updateDevice(idWiFi,'',i)

local idA = 100
domoticz_updateDevice(idA,'',b ..";"..a*1000)

local idW1 = 101
domoticz_updateDevice(idW1,'',f)

Today I've received my HomeWizard P1 Wifi dongle.
I've installed the plugin from https://github.com/Eraser3/HomeWizard-Wifi-p1-plugin
I've added the HW wifi P1 meter in the hardware.
The devices showed up in the device tab.
so far so good.

Now I notice that the "Current power usage" and the "Total power usage" show the watts multiplied by factor 10 in Domoticz.
- meter screen: ~300W
- HomeWizard app: ~300W
- Domoticz: ~3000W

I see it has occurred before when reading: https://github.com/Eraser3/HomeWizard-W ... in/pull/12
does anybody know how to fix this?

I guess I should use the fork of gettevan instead? https://github.com/gettevan/HomeWizard-Wifi-p1-plugin

[DomoFlits]

I've switched to the plugin.py from the fork from gettevan.
now the values are not multiplied by 10.
The fix from gettevan was never implemented in the Eraser3 plugin.
