Raspberry Pi4 - Up & Running

UPDATE:
Having issues with temperature and the CPU throttling back, looks like I need a fan.

could you share your sensor configuration about the cpu throttled state? Also undervoltage would be interesting.

Edit: it’s this right: https://github.com/custom-components/sensor.rpi_power

No its a script I did using the vcgencmd command and updating via json using a crontab, probably does the same not looked at that custom component.

My pi 4 went down from around 75 C with the genuine case and heatsinks to around 68 C with a metal case and heatsinks.

Only when it takes a snapshot the temperature rises to around 85 C.

Does your rpi4 seem slow? Ring videos play even slower than on the rpi3b+ and the damn thing is hot. sits at around 60-65C with a small heatsink attached.

Have any Pi4 owners run a Hass benchmark? If so mind sharing the results please?

Benchmark info:

james_hiscott · August 20, 2019, 7:39am

This on a Pi4 with 4GB of ram, however HassIO can only use 1GB currently

h4nc · August 20, 2019, 8:42am

good to know, do you have a source for that information?

slovenc · August 20, 2019, 8:43am

i can show you a screenshot from my build, shows only 1GB of ram.

h4nc · August 20, 2019, 9:08am

ok, no I believe you, let’s hope we can soon use the full 4GB RAM

Nice that’s over twice as fast as I was getting with my Pi3

It would be nice is anyone running HA under Venc could add async benchmarks for the Pi4 also, I guess it’s going to be around 3.3 seconds

david_b · August 20, 2019, 12:08pm

I would not say it’s slow but also wound not say the is a massive improvement either.

I have solved the overheating issue by getting a FLIRC Metal Case, not cheap but I am worth it.

Akriss · August 20, 2019, 5:24pm

Thank you. for the benchmark info.

Akriss · August 20, 2019, 5:33pm

Its faster then my currant Hassio box an old Zotac HD-ND01-U. that clocked in at 8.1 something.

james_hiscott · August 30, 2019, 10:43am

FYI the memory problem is fixed:

david_b · August 30, 2019, 10:49am

Excellent just checked mine and it’s also working now, not sure on when it was fixed but works on 0.98.1

kslb · September 18, 2019, 7:25am

Can you give me the sensor code for undervoltage and everything what is in this glance card… thank you…

h4nc · September 19, 2019, 9:46am

From here

We have published a release candidate of HassOS that is compatible with the new Raspberry Pi 4. Download it here.

Do we need to flash the sd card again and restore a backup to get this updated or do we also get this directly in hassio (system)?

david_b · September 19, 2019, 11:27am

That depends on your skill level as it’s a script that you would need to edit and modify to your server and token, have MQTT up and running also set to run the script as a cron job.

If you understand everything above then yes, but I don’t have time at the moment to tidy up the code, provide detailed step by step instructions and make user friendly.

The was a mention of another component that did the same that my be easier to set up.

D.

p.s this probably won’t work in HASSIO only developer installations
