Mopeka Standard Check BLE Sensor — ESPHome or Mopeka Pro Check BLE Sensor — ESPHome or Mopeka - Home Assistant. I haven’t checked their price or availability in NZ.
There are a few vids floating about of using a load cell to keep an eye on it HX711 Load Cell Amplifier — ESPHome
Oh cool, thanks! It looks like I want some mopeka sensors. Not sure where to find ones for the 45kg tanks though, will do some more research!
One thought, you better remember to take them off before they take the tank away. Another automation 
Haha yeah I was just thinking about that too. Maybe attach it to something on the ground with a chain
Hi Nathan, I guess you may already have a solution for the gas bottle weighing. If not, i seem
to remember seeing that the gas bottle selector valve has a lever which the pressure differential flips over when changing supply bottle. Could you attach a microswitch to this lever and use the signal?
Just wondering…
Keep tinkering regards
Dangerousdave.
Hi David, yes we do have a gas bottle selector that switches over to the next bottle. I was also thinking about putting a Zigbee door/window sensor on it and tracking the open/closed state in Home Assistant. But in the end I decided to buy a “Lippert Bottlecheck Bluetooth GAS Gauge Single” from RV Super Centre. It just arrived a few days ago and I haven’t set it up yet, but it will also be nice to check the level of the gas bottle and see how much we are using each day, etc.
I just decided to get one, and will swap it over to the other gas bottle when one runs out. We only replace one bottle at a time, so hopefully I won’t lose it
Back when we had gas bottles in Auckland I was tinkering with load sensors and trying to weigh the bottles to determine home much was in the tank. I got some progress but then we moved down south with no more gas…
I finally got the bluetooth gas bottle sensor working. I got the “Lippert Bottlecheck Bluetooth GAS Gauge Single” from RV Super Center.
It was actually a bit of a mission and ended up taking most of the afternoon and evening. Our gas bottles were on a slight slope and the sensor complains if it’s not level, so I used an old monitor stand with 4 adjustable feet.
It also complains if the gas bottle is sitting directly on a flat surface (something to do with the ultrasonic sensor), so I used a few bits of wood to give it some more clearance. I was getting errors and 0-1 stars for quality until I leveled it properly.
Then I installed ESPHome on a ESP32 NodeMCU development board, and set up the Mopeka Pro Check BLE Sensor integration. The range is pretty decent, I was able to plug it into a socket about 8 meters away through a wall and it picks up the BLE signals.
Then set up a dashboard and some template sensors:
I set up utility meters to track daily/weekly/monthly usage, average daily usage over the last 14 days, and estimated days remaining.
I set up some notifications when the level falls below a certain level.
Will have to test it and see how the sensor works next time a gas bottle runs out.
Here’s the YAML I used for the sensors. Has some hard-coded values where I’m estimating that a new bottle has ~66L of gas and a level of ~750mm.

Now I just need to write a script that automatically fills out and submits the order form: Order Online - Rockgas
Maybe later!
Like you I have the same gas setup (Rockgas as well), and have thought about monitoring them - dont you have to manually change the sensor over to the bottom of the bottle every change?
FYI - I live in TGA and have all of our lights (Hue and Nanoleaf), Zigbee and Thread via SkyConnect, Z-Wave via USB stick, some Shelly stuff and a BT proxy. All of our internal and external lights, exterior doors are controlled via automations etc. I use a lot of timers in rooms with monitoring via hue motion sensors. Starting to get into ESPHome now and been using HAOS for about a year. I like the “if ute is home and ive forgotten to lock it, lock it at night” automation 
We are all apple users here, so using homekit to trigger a helper in HA when we leave the house etc. This has been absolutely rock sold for home presence detection.
Things I want todo:
Last time I looked they were pretty stingy on providing an api. Like, they didn’t.
Yes I had a look and spotted an API which seemed to relate to ocean data.
Care to share? I am not a big fan of scraping.
Sure thing. Let me get it working correctly first, then I’ll share. Ive currently got all the “Current Weather” stuff working in basic form.
Hi,
Fairly new to home assistant, but using it now in anger for a couple of months. I’m a kiwi living in South Island. Reason for post is I’ve got warm floor thermostats/title heating working with home assistant and from there into HomeKit. Required a mod to the local Tula integration but works pretty well. Warm floor is a Nz company so if anyone is interested in it let me know. I’ve had a chat to the company and they are going to put a howto up on their website.
Cheers
Miles
I did get this going and it seems to be fairly reliable, however I have not checked it out fully and I know that there is still issues at certain times of the day with the data. Plus all the div IDs are specific to Tauranga and you would need to change them for other cities. I just wish we had a proper API provided by the met service.

This is now all working well in the Energy Dashboard having just installed a Shelly EM with a 120AMP clamp onto the main house grid feed.
Now i have added the suggestion as follows which splits out the electrical charge and the daily power shop charge. I had to add the following entities:
- sensor:
- name: "Powershop Supply Charge"
unit_of_measurement: "Wh"
device_class: energy
state_class: total_increasing
state: >-
{{ int(as_timestamp(now()) | timestamp_custom("%d")) + 1 - int(as_timestamp("2023-08-03") | timestamp_custom("%d")) }}

Then I could select the entities in the Energy Dashboard setup:
And it’s all working!
New to HA but loving it so far. Does anyone know if there is an integration that scrapes Meridian Energy usage data for the home energy module?
No integration. You have to use multiscrape via HACS and then bring in the data. I could not find anything done already unfortunatly. Note Im only using it to get the powershop daily prices, not my usage. For usage im using a Shelly EM with a 120AMP clamp.
