add-night-mode-functionality

[apo-mak]

This pull request introduces new switch controls and configuration improvements to all four ultimatesensor-v1 YAML files, enhancing user control over the OLED display, PM sensor, and adding a night mode feature. The changes improve modularity and allow users to enable/disable hardware features dynamically.

Switch Controls and Feature Toggles:

• Added a template switch for the OLED display (lcd_display_switch) in all variants, allowing users to turn the display on or off via software.

• Introduced a template switch for the PM sensor (pm_sensor_switch) in the "complete" variants, enabling dynamic activation or deactivation of the sensor and its update interval. ([[1]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-eee30ec6755c8a53ad71061a470d33e686ca0bda6707cb407cb2c522e455b334R914-R958), [[2]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-88da9783ffb25c7106ab4ecb1b9db30e14cabc15050b8b30b08f635b7391bc2dR887-R931))
• Added a "Night Mode" switch in the "complete" variants, which simultaneously disables/enables both the display and PM sensor for low-power or night-time operation. ([[1]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-eee30ec6755c8a53ad71061a470d33e686ca0bda6707cb407cb2c522e455b334R914-R958), [[2]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-88da9783ffb25c7106ab4ecb1b9db30e14cabc15050b8b30b08f635b7391bc2dR887-R931))

Sensor and Display Configuration:

• Assigned unique IDs to the OLED display (id: oled_display) in all YAML files, enabling direct reference and control from other components. ([[1]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-a3770364b76f54f220ce4aaacea9e29ed3565ed2bf44624610833693d617bda9R90), [[2]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-8c709a45ae1fcc1c41cba43ff0ea2a90aa3820fb34e655e332429506c56a2316R93), [[3]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-eee30ec6755c8a53ad71061a470d33e686ca0bda6707cb407cb2c522e455b334R108), [[4]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-88da9783ffb25c7106ab4ecb1b9db30e14cabc15050b8b30b08f635b7391bc2dR90))
• Added an ID to the PM sensor (id: pm_sensor) in the "complete" variants for easier management and integration with switches. ([[1]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-eee30ec6755c8a53ad71061a470d33e686ca0bda6707cb407cb2c522e455b334R170), [[2]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-88da9783ffb25c7106ab4ecb1b9db30e14cabc15050b8b30b08f635b7391bc2dR151))

Global State Management:

• Introduced a global variable (pm_sensor_enabled) in the "complete" variants to persist the enabled/disabled state of the PM sensor across restarts. ([[1]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-eee30ec6755c8a53ad71061a470d33e686ca0bda6707cb407cb2c522e455b334R353-R356), [[2]](https://github.com/smarthomeshop/ultimatesensor/pull/4/files#diff-88da9783ffb25c7106ab4ecb1b9db30e14cabc15050b8b30b08f635b7391bc2dR334-R337))

Seems like the switch to toggle off the pm sensor does not work, did you test it?

yes and i thought that it works.
It looks like the function command does not work reliably or it was a fluke so I have replaced it with a direct I2C command.

I tested .turn_on() and .turn_off() for the display and it didn't work. I was able to create a switch in the UI that toggles the contrast between 0% and 40% which has a similar effect. I'm just about to create a PR for this now.

[dwainscheeren]

Very strange because it works here on my Ultimate Sensor turning on and off the display

it works on my end, especially the "night mode.
can you try re-flashing it? do you see any logs when you toggle it ?

[apo-mak]

@dwainscheeren is it ok to merge this pr ?
did you encounter any problems with this build ?

[dwainscheeren]

Let me check, there are now 2 PR's for the same thing :P Let me check what is the best I can do and merge it.

Quick note, the other PR is only for the display.
This one also stops the PM sensor because the fan is very noisy at night.

So if you go with the other one, please copy the “PM turn off” part of the code ( and or the night switch for the Home Assistant)
:)

[dwainscheeren]

Yes but esphome released an update with also sps30 idle mode now :) so need to look into that also
