Ultimate Garage Door Control With Home Assistant Automated Management
This is an interesting project to get a simple motorised garage door opener to connect with some intelligence via Home Assistant.
One could split this into two phases, with the first being really simple and not interfering with the motorisation itself. The first phase could just use the reed switches to indicate on the Home Assistant dashboard whether the door is fully closed, open, or somewhere in between (i.e., jammed or stopped). You could set easy automation rules too to have a timer running when the door opens, and if it is not closed within say 2 minutes, to send an alert to you. Or if the door opens after dark, send an alert to you. The sky is the limit with the rules you can build into Home Assistant to automate things for you.
Getting fancier on phase one, you could add an ultrasonic detector to look downwards and see if the car is in the garage (shorter distance) or it is out (full distance to the floor). The opening / closing automation could take the car’s presence into account as well.
Phase two would have some interface with the motor. But this can be quite simple too, as even my old 15+ year old DC Blue garage opener, as a manual test button on the board. This is for simulating the remote-control button. Some also have a switch on the wall for this purpose. Either ways, you can use the contacts of this button / switch to make or break the circuit to trigger the opening or closing. So, no need to have some super fancy, expensive door opener to get something like this done.
This is also not the only way to do this project, as Home Assistant has a number of project recipes to work with different devices. So, consider others if this looks a bit complex, or consider my phased approach too, to get yourself tempted for phase two.

Monitoring Battery ‘Time To Go’ on Solar Systems or Inverter Systems (How to Calculate and Display)
In this video I (try to) explain how I used battery current readings and the battery state of charge, to display gauges on my Home Assistant dashboard showing the amount of battery time left based on the current inverter load. It adjusts as the battery level (SoC) drops and as the loads change.
But it was not all plain sailing as some oddities arose which needed to be accounted for, and I also expand on these. Two issues I had were to estimate time left when the battery is actually charging, and also how to deal with very small loads that show unrealistically long projection times.
As I explain in the wrap up, even if you have a plain battery inverter or other device that does not have the MQTT protocol, or have Modbus registers that can supply this information, there are other innovative ways of reading loads, voltages, and currents that may also work for you. So this video need not only be for those using Victron or similar solar systems.

Open Source Self-Hosted Home Assistant home automation with a Modbus TCP interface to a Victron Solar System
Home Assistant is an open source self-hosted home automation tool that puts local (not external cloud) control and privacy first. My system is running in a Docker container on a machine at home.
Home Assistant is more than just the monitoring and managing of smart home switches and lights. It has powerful automation that can be triggered by all sorts of events or device states to notify you, or manage even solar systems, garage doors, and much more. For example, I have an automation that announces it has started to rain so we can get the washing off the line before it gets too wet.
In this video I show what my HA dashboards look like, and how I managed to read lots of information via the universal Modbus TCP protocol from my Victron solar energy system, and to also write data back to the Victron system to change the battery minimum state of charge values from HA (or other registers).
I have shared my config files on a Github page so that it is easier for others to replicate some of the same functionality (without spending 4+ hours like I did on a single value statement line).

Hi, I'm #newhere !
I'm a man in the 40's from Norway. Now living and thriving in the northern parts, though I have my roots in #Bergen city.
I've been exploring alternatives to the hegemony of #google and #facebook / #meta and their likes for some time. Not entirely new to the #fediverse, as I've been using #mastodon for a while, but this is my first time in the #diaspora realm.
A couple of topics I find interresting:

OPNpool integrates the functionality of a traditional Pool Controller into the modern smart home
It can keep tabs on the status of the connected controller, pool pump and chlorinator. This provides not only a more convenient solution than physically interacting with the pool equipment, but the ability to create automations that runs the pump for a duration depending on the temperature.
Features:
- Visualizes the status of the thermostats, pump, chlorinator, circuits, and schedules.
- Allows you adjust the thermostats and toggle circuits
- No physical connection to your LAN
- Supports over-the-air updates
- Easily one-time provisioning from an Android phone
- Integrates with MQTT and Home Assistant
- Accessible as a webapp
- Protected with IP68 waterproof case and connectors
- Does not require a power adapter
- Open source!
This device was tested with the Pentair SunTouch controller with firmware 2.080, connected to an IntelliFlo pump and IntelliChlor salt water chlorinator.

Je regarde pour debuter en domotique a la maison mais bien entendu respectueux de la vie privée. Il y a la console mais surtout les périphériques. J'ai un premier besoin de type vidéo. Meme si j'aimerais je n'aurais pas le temps de trop faire moi même, je m'oriente vers des materiels du marchés compatibles avec domoticz ou home assistant. Vous avez deja mis en place ce type de chose?
