I have posted our Solar Generation and Export numbers for April

https://www.bazmac.me/blog/april-solar-generation-and-export-numbers-2024

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@bazcurtis Interesting - thanks. I'm always wondering if I should swap to Agile - your average import rate over the month is around 60% of mine; in theory I should only import at off-peak @ 7.5p/kWh but there's always a small amount of use during peak periods (e.g. while the inverter catches up to the kettle being turned on etc).
Is your management/automation 100% hands-off, or do you need to manually tweak things on a regular/semi-regular basis?

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@bazcurtis ...I subscribe to Octopus Watch, but some of the tariffs (including Intelligent Go) are "unsupported" because cheap rates set by car charging aren't exposed in the Octopus API. As things stand at the moment, Octopus Watch claims my bill is cheaper than it would be on Agile, but I think that might be because it isn't taking everything into account. Your average import rate looks impressive...

...here's my Octopus Watch comparison

ChrisWarwick, to octopus
@ChrisWarwick@mas.to avatar

My electricity bill for last month: Import costs ~£50, export credits ~£90. Overall credit for April: £40 (including standing charges and running an electric car).
This is thanks to Solar PV, a House Battery and a flexible tariff from (Intelligent Go) - all orchestrated with
Capital cost was high but well worth it 👍

Screenshot of my electricity bill showing an import of 410kWh offpeak, costing around £30; and only 10.8kWh at peak rate, costing around £2.80. Standing charges for the month are £17.50.
Screenshot of a graph from my electricity bill showing a profile of a typical day's usage; there is almost no grid consumption during the peak rate period.

@bazcurtis I have a very similar story, October 2022 install. I spent last year getting to grips with the whole thing (at a rather leisurely pace, it has to be said) and setting up integrations and automations, as well as changing tariffs. Shout-out to all those people who produce such great HA integrations that make proper management possible!

You work in IT and want a job where you can really save tons of CO2? Vamo, a heatpump startup, is looking for people to join their IT-team to help them connect heatpumps to the cloud!

P.S. We are also looking for interns and working students!

This afternoon the outdoor temperature just grazed 16 degrees C. At 15 deg I can go out without a coat so I declare that PROPER Spring has arrived. Unfortunately that meant I also had to go out and finish deadheading and raking before the green stuff erupts. I’ve left all the old dead stalks out for the birds, who sounded very horny and in need of building materials.

Started to play with Sections in Home Assistant and I love it. Thanks to @madelena and the team at @homeassistant for this release. Some examples. Please read the alt text. The MacBook Air version would still have room for a 4th column, but it seems I am limited to three. Hopefully that can change or I am wrong.

I believe this is just the start. I can't wait for the next released. I have always found dashboard very frustrating.

#HomeAssistant @homeassistant @homeassistant @homeassistant

I dragged the loft and bedroom temperature card to Lounge and Hallway section respectively.
My original Dashboard. Zoomed to 80% so you can get the idea. The office and gym columns were vertical stacks
This is my MacBook Air view.

@bazcurtis @madelena @homeassistant I agree about card sizes. I especially want to be able to increase a card's width (e.g. a card that spans two or more columns - for the Sankey chart card etc) #HomeAssistant

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@bazcurtis @madelena @homeassistant Yeah, that'd be good! The custom grid layout card is just too picky and has to be micro-managed when trying to make layout changes - plus it understandably doesn't integrate very well with the UI editor. So anthing that improves the situation is good imho

About to start our heat pump journey. We have the quote from . We need to start the planning permission application. As the Green Party are the majority on East Herts District council you would hope it will pass easily.

I need to start writing about this on my blog.

@bazcurtis Good luck! I'm hoping to follow at some point, it would be really good to hear about your experiences 👍

Mum had her heat pump install completed day. It is looking. She is now totally gas free. Interested to see how it goes from here.

@bazcurtis Looks good. Is there a Home Assistant integration for that Daikin (cloud-free... modbus?)

@bazcurtis Thanks :-) I'm very much in the 'research' phase atm, going off to the "Everything Electric" (Fully Charged) show at the end of March for further inspiration. My biggest concern is finding a really competent heat engineer...

Pleased with the way the Versatile Thermostat integration in #HomeAssistant is working to control the heating in my office. Just waiting for a more appropriate temperature sensor to be delivered next week.

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@steve Love the graphic Steve - is that the History-Graph card? I like the way it displays the heating on/off along with the respective temperatures; also, the 2 graphs together. Would you be able to share the yaml?

@jerzone@techhub.social avatar

I installed SolarEdge integration into HomeAssistant around beginning of month and it was working just fine. Somewhere along the line the lifeTimeData/solaredge_lifetime_energy quit working and the entity shows as “Unknown”. Current power is still fine. Check the json from API call and the data is there and is fine, it's just something in HA quit parsing it.
The code on git for this integration seems straightforward, but I don't know enough about the file structure of HA to even know where to find the installation and check the files (File Editor exploring hasn't helped). Have deleted/reinstalled, no change. Any advice?

#homeassistant

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@jerzone My first guess would be that the integration hasn't been able to connect to the Solaredge API (possibly temporarily?).
There are two (three actually) Solaredge intergations that I'm aware of - I use the "standard", built in to HA, API integration (https://www.home-assistant.io/integrations/solaredge) and also the local (Modbus) integration: https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki
Most of my stuff relies on the modbus connector (3 second updates).
If you look at the sensor history, when were they last updated?

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@jerzone That's the modbus integration I'm running... What was the issue?

It looks like there are almost no #zigbee thermostats available now for the typical low-voltage forced air gas furnaces.

There are several for hot-water systems, and a few for electric baseboard heating.

A couple that were available are have gone. The Zen product (designed & made in St.John's NL Cda) is gone, after they were bought out by Mysa.

Maybe the only option is KONOz, which is expensive and has sketchy specs.

ChrisWarwick,
@ChrisWarwick@mas.to avatar

@ottaross Highly recommend NSPanel (https://sonoff.tech/product/central-control-panel/nspanel/ (not the NSPanel Pro, which is Android based)) - I've replaced 5 room thermostats with these. No internet access required - fully local. Customisable. Lush!

i managed to push ~4.2kWh to the grid during today's DFS event. This equates to around a 5kWh reduction in normal usage (which makes sense as I have a 5kW inverter :-)). Will be interesting to see what happens to my

Thanks - do you have (or can you help me find) any definitive Octopus info on the subject?
Following your suggestion I requested access to the Octopus Smart Energy forum, but received a "sorry" email from them last night - only for Agile customers 😞
Anyways, I'll let you know what I see on my bill/octoplus when it shows up...

I eventually received a mail from Octopus - then, at around 11:23 GMT my HA automation ran and joined the session.
I turned off my battery as soon as I saw you posts, but it was already down to 75% - it would be good to get notifications earlier....
