The HomeWizard P1 meter does not store any data, it just serves through the API and sends to the HomeWizard server where you can have access to historical data for 1 year for free, longer period for 1 EUR/month as I remember. But I don’t know what format you can get it off from them.
HA stores the long term statistics in the database, if you move your whole config, including the database to a new server, then you will have access to the historical data. Especially if you set up the Energy dashboard.
Wondering about gas meter… my P1 shows it in m3 but the price is calculated in kWh… so the price isn’t correct. Don’t we need to convert it?
The sensors we create for daily, weekly and monthly… does it store the data with the price of that month? Meaning when you change the price on the 1st of the month, it doesn’t change the calculation of the month before.
Update: simple trick is multiply the kWh price by 10,26 for low caloric gas and 11,51 for high caloric.
Update 2: when a new month starts and you update the kWh price, it adapts the previous month price also. Would be great if it keeps the history and price of former months. Anyone an idea?
Hi all. I am using the watermeter for couple of months now in HA. All working great and collecting data etc.
This week i received my HA green device (to run HA via there instead of a VM on a pc slurping energy 24/7 :P)
The integration is automatically detecting the homewizard watermeter, but when i press configure i get “Device unreachable, make sure that you have entered the correct IP address”.
It is the correct IP (checked the device in the modem etc). It also working in the homewizard app and has a 100% wifi connection. Local API is stil enabled. The watermeter is also still working correct in my HA installation on the VM.
Is it possible you can only connect the watermeter to 1 HA installation? or should this work inside 2 installations?
(don’t want to remove it n my current install just to find out i cant reinstall it again…)
Hi, I’m using a HomeWizard KWh meter 3-phase, integrated into my Home Assistant Core 2023.11.3. I cannot find where I can change the update frequency of the KWh meter 3-phase, there is no such setting available in the UI. Can you tell me how to change this?
You have to disable automatic updates and create an automation to refresh your data when needed. I am sure there is a guide somewhere but can’t find it.
In essence;
Go to your devices and find your device. Click the ... and select ‘System options’.
Disable “Enable polling for updates”
Make an automation that is triggered when needed. It must call the homeassistant.update_entity service.
Well I’m just trying to reduce the refresh cycle of this KWh meter 3-phase. Now it’s updating every five seconds and I do not need energy data in this granularity. I want to change the update cycle to every 60 seconds to reduce unneccessary data.
