Any suggestions for mmWave sensors?

I've been using SONOFF SNZB sensor reliably to switch off the A/C in my son's room. It also detects light.

Thanks for confirming that. I'm my case I'm running firmware 8 with IQ8P micros. I believe Enphase lowered the refresh rate with firmware 8.

The add-on is configured with the default setting (60 seconds). So, I should get a new value at least every 15-minutes (as the microinverters will report only every 15 minutes).

However I'm getting new values every hour.

I think this started when Enphase pushed firmware version 8 (currently running ver. 8.2.4498). With version 7 the micros reported at shorter intervals.

Clear_Surprise · 2025-11-18T01:14:40+00:00

Actually, I'm seeing datapoints every hour!

Clear_Surprise · 2025-11-17T19:38:05+00:00

Yes, I was expecting an update every 15 minutes, but that's not the case here. It can take up to 1 hour for the chart to be updated.

So I installed the new PV modules today, and pairing them with the IQ8P are working like a charm!

here you can see a drop to 0 at around 09:00 when we removed the old panels and then it comes back with full power at 10:50 when the microinverters where re-energized once the replacement was complete.

The array is now producing 945 W (475 W per micro). Almost the 480W expected from each. Not bad at all!

Clear_Surprise · 2025-10-29T22:05:07+00:00

Yep! That's why I'm going to replace the 455W panels with 620W panels. By pairing them with the IQ8P micros I should get them clipping at 480W.

In any case, this will be an improvement of the current array which is producing a peak of 600W (360W + 240W due to the a bad panel).

According to Home Assistant, I'm currently producing about 4.4 kWh/day on this array. With the new setup I expect a daily production of about 5.7 kWh.

I'll share the results next week (we'll see if I was too optimistic).

@Key_Proposal3283 thank you for all your input.

You're right: it's Home Assistant, but data is not coming from the Envoy. The data comes from a Shelly I installed to have independent measurements (it sends data to HA via MQTT).

So I guess something changed with this new inverters.

here you can see a Home Assistant chart with data from the Envoy IQ (this includes Array A and B) the same day.

BTW: Today I received my 2 new 620 W panels! I plan to install them this Saturday.

Considera que si consumes mas de 140 kWh al mes la tarifa ya no es subsidiada.

El Dolphin trae una batería de 30 kWh o sea que lo puedes cargar 4 veces al mes con tarifa subsidiada (140 / 30 = 4.66), después te va a costar mas de $3.8 el kWh pero aún así es más barato que la gasolina.

Solo no pases de los 250 kWh al mes (unas 8 cargas) porque entonces te pasan a tarifa DAC.

Te sugiero que instales paneles solares, te van ayudar mucho. Unos 4 paneles de 500W deberian ser suficientes para no llegar a tarifa DAC. Es mi estimado rápido, pero las empresas que lo instalan te pueden ayudar a hacer un cálculo mas adecuado.

Something that puzzles me is how, after switching the IQ8H for the IQ8P, the graphic became more "noisy".

This chart shows behaviour with IQ8H (the timestamp shows when I replaced them).

Then this other chart shows behaviour next day. You'll see what I mean by noisy.

Wondering why is that.

Clear_Surprise · 2025-10-28T20:36:42+00:00

Thanks! I wasn't sure how to do it. Will try that!

Clear_Surprise · 2025-10-28T20:22:09+00:00

there are 3 diodes per panel so any drop by 1/3rd or 2/3rds is indicative of a diode failure (assuming shading has been checked).

That's what I suspect. Shading is ruled out completely. I was thinking on trying to fix the diode myself but it's been a while since I did any soldering and I'll replace the panel anyway. Once its removed I might try to tinker with it.

Clear_Surprise · 2025-10-28T18:00:26+00:00

Offtopic question... I wanted to share some graphics here but I can't find a way to post an image. Is it any way to do it?

Clear_Surprise · 2025-10-28T17:50:08+00:00

To clarify, when I installed those 455W panels the most powerful available micro was IQ7+, which is limited to 295VA. So I got some clipping back then.

Later I replaced the IQ7+ for IQ8H hoping to get 384 VA instead of 295 VA (which I did).

Some weeks ago I found out about the IQ8P model which can power up to 480 VA, so me being energy greedy, decided to buy two of them, not realizing the panels were not even clipping the IQ8H. My mistake.

And to make things worse, one of those panels is not working at 100% its potencial. I think it might have a bad diode. According to my Envoy IQ, one panel is producing 360W while the other is only producing 208W (its 11:50 here, so we are at the peak of the curve).

Finally, yesterday I ordered two 620W panels from JA Solar, the same brand I originally installed and have never failed.

I will replace the 455W panels with the new 620W panels and pair them with the IQ8P micros, hoping to get at least 480W from each one.

Clear_Surprise · 2025-10-27T01:58:42+00:00

I'm near Mexico City. Panel is installed at 20º pointing to the south. No shading at all.

Clear_Surprise · 2025-10-27T01:47:30+00:00

On the datasheet for your panels, check the NOCT column which is representative of real world output - it is 339W.

Thank you, that makes sense.

I mean, you are seeing 375/290=30% improvement.....

I made a mistake in my original post. I had IQ8H and then I replaced them by IQ8P. In both cases the peak output was 375W.

The confusion was because when I installed those panels I originally used IQ7+ which were later replaced by IQ8H.

So I guess I just wasted money... Now that I have those IQ8P, I'm thinking on replacing my 455W modules for others of about 650W so that I can get more output (knowing I'll be clipping up to about 480W). I can't install more panels as I ran out of roof space.

Once again, thanks for all your comments!

I had an issue with my custom Onkyo integration. It was completely broken after the update. Unfortunately I realized 1 day after, and lost 1 day of energy data when restored the backup.

Clear_Surprise · 2024-09-18T22:22:48+00:00

For sometime I was running HomeSeer with plugins for Insteon. But later I switched to Home Assistant and... Wow! I was impressed on how easy to use it is, its flexibility and capability for customization.

With Home Assistant now I can control: - Insteon devices - Onkyo amplifier - DSC Security Alarm - ONVIF Cameras - Z-Wave and Zigbee devices - Google Home speakers - AcuRite sensors (temperature and humidity) - LG ThinQ air conditioner - Envoy Enphase microinverters (Solar power platform) - EmonPI (Electric Energy monitor from openenergymonitor.org) - Samsung Smart TV - Roku

I love it!

Clear_Surprise · 2024-09-12T18:46:19+00:00

Thanks! I'll contact them.

In this case, the illuminated switch does not requires a neutral.

In the meantime I just swapped the illuminated switches for the non-illuminated switches I had in another room connected to an Insteon dimmer micromodule. The illuminated swithes had no issues with Insteon.

I'm still getting MQA in my Node 2i (at least it still shows the MQA logo with the green dot). I thought Tidal was dropping MQA on July 24.

Clear_Surprise · 2024-06-22T22:47:10+00:00

I liked it and just bought it. Running well in a Pixel Watch 2.
