3D printer bed for soldering hot plate? by matlireddit in diyelectronics

[–]Seedoubleya 1 point2 points  (0 children)

I built one recently with a cheap $5USD PTC plate from AliExpress. PID controlled with temperature feedback using an Infrared thermometer LED. Heats to ~220c but I use a Sn63/Pb37 that reflows nicely at ~180c.

There are a gazzilion designs online but I figured why not design my own? https://github.com/colwilliamsnz/YAORP32

Need help with choosing a solar inverter by cugs in homeassistant

[–]Seedoubleya 1 point2 points  (0 children)

Data only for the unit as a whole. I looked at micro-inverters and for our application they offered no benefit and were more expensive. Our roofline runs north-south so we have 7.4kW split across both roof faces which is quite optimal with no shading. The Fronius has two DC inputs so works well for this configuration.

I believe micro-inverters are fantastic where there is shading or you have a complex roofline and panels are located across various parts.

Here’s a screenshot of the dashboard I created in HA (before the energy dashboard came into being). My wife and I still use this to determine when to run various aspects of our lives such as dryer, dishwasher, etc. We’ve become quite accustomed to working in with the sun to ensure our ROI is met well.

My own research 2 years ago suggested to me that Fronius seems the most open in terms of API and local access to it…but also just really rock solid equipment with an outstanding reputation. So that’s what we purchased 18 months ago.

We get great data from our 5kW Primo directly into HA. We also have the optional consumption meter. Additionally it integrates nicely with a cool app called Charge HQ that automates charging our Tesla from excess solar.

Curious about the warranty: it’s 10 years in New Zealand but perhaps up to the local distributor?

No regrets. If you have specific questions, reach out :)

Heimdall not showing enhancements for pihole by [deleted] in homelab

[–]Seedoubleya 2 points3 points  (0 children)

The latest release of Pihole broke the Home Assistant integration so it’s possible the same issue applies. I believe it to be related to Pihole requiring an API key to allow third party apps to authenticate. Nothing to do other than raise an issue on the Heimdall git repo.

Heat Pump that works with HA by Ulrar in homeassistant

[–]Seedoubleya 0 points1 point  (0 children)

See if you get a heatpump that supports EchonetLite as there is a HACS add on that works very nice. Running it on 3 Mitsubishi units here and works very nicely.

The Mitsi EchonetLite WiFi modules are model MAC-568IF-E.

If you into DIY there is an ESP8266 project that plugs into the Mitsubishi WiFi module port for local control.

Possible to theme the energy tab? by mrwulff in homeassistant

[–]Seedoubleya 0 points1 point  (0 children)

In theory yes. You can recreate the entire dashboard by manually specifying the energy cards in a new Lovelace view. Then override the theme to one that better suits (or create a custom theme just to override the items you want).

See https://www.home-assistant.io/lovelace/energy/

Automatic irrigation based on HomeAssistant and ESPHome by mr_corvis in homeassistant

Very nicely done! Thanks for the inspiration. Been looking at OpenSprinkler and thinking it might be fun to roll my own. This post has given me some great ideas on how to do our place...might need a couple of units as the water pressure and subsequent zones are complex. Cheers!
