Maybe better, one relay for each power supply circle. Vcc looped over all relay to GPIO from the ESP. If the signal goes to zero, check all earth leakage circuit braker. circuit.png Why two relays? Could just feed the switched output of the first relay to the ESP? The downside is that I would have ...

The "aardlekschakelaar" you're talking about is probably not 1-to-1 mapped to a circuit group in your house. According to the NEN1010 regulations, you may have up-to 4 groups on one earth leak breaker circuit. So that may give some 'discount' in the number of units needed. Another thing y...

manjh

Makes sense. I was already thinking of an advanced device, connecting to each of the groups, but a more pragmatic approach makes more sense. I already have about 15 devices, I think I will take inventory to see which groups they are attached to. With a bit of luck I will only have a few left open, a...

After a two-week holiday, I came back home to find the "earth leakage circuit breaker" (is that an English word?) to have tripped. A good part of my house was without power, including the freezer. Opening the lid was not pleasant, all food was thawed and rotting. I will spare you more deta...

Leeft dit topic nog? Ik gebruik enkele Chinese PIR sensors. Zolang er nog fut in de batterij zit doen ze het goed, maar zodra de batterij spanning "valt" zijn ze onbetrouwbaar. Soms werken ze, soms niet. Ik had liever dat ze er gewoon mee ophielden, dan weet je tenminste waar je aan toe b...

My favourite Chinese shop sells a very cheap device that can be plugged into the USB power supply, and then the cable to your device plugs into the Chinese device. It shows V and A. I did not search for the cheapest, but I know there are several differend kinds for varying prices. This is worth havi...

manjh

Do what I do, when all else fails: dig out the ESP unit, bring it to your desk, and use an old-fashioned USB cable to connect to serial. This way you should be able to load.

manjh

Nothing? I'm surprised. Radon is becoming a big issue in some parts of the world, so I expected people would be into detection!

manjh

Oh, from R147 to mega is a no-no using OTA. I'd say you should not fix what's not broken or if you really need new features you need to connect the unit to a PC and do the complete new flash. Just remember to document everything you want to reconfigure! Yep, my thoughts exactly. "If it ain't b...

Great, just my luck. I use a mix of Mega and B147. I could upgrade, but some units are hidden away and I don't feel like digging them out for this reason. Upgrading OTA does not always work from B147 to Mega, I found out the hard way. Needs a physical USB connection to get things right. So, I am ba...

The sysday solution seems to work for Mega units, not so good for build 147.

Has anyone looked into the options to do radon detection/measurements via a sensor attached to an ESP unit?

You could add a counter which is adding +1 each day at a given time. Once the timer hit 30 you do a reboot. Sounds like a workaround... does this mean that "date" is not available in rules in the same way as "time"? When I use this method, the unit will reboot every 30 days, not...

I have used "On Clock#Time=Sun,04:00 do " to trigger a reboot once a week, in order to prevent the 49 day crash. It is working well, but I think I want to change this into a reboot once a month. How can I do this? I've looked at the wiki, looking for something like "Clock#Date", ...

It's a genuine unit as far as I can tell. But it could be a QA approved Senseair unit that has been mistreated at customer site. And a employee may have taken it and sold it on AliExpress? This is just guessing by me. Looks like there are several sellers on Ali with this item, so there are probably...

that last sentence is spot-on. Most of us should be OK with readings that may not be accurate down to the decimals. Personally I use S8 sensors as an indication for ventilation. So I go by the Domoticz classification of good, fair bad, etcetera. Same for temperature and relative humidity. I treat th...

hmmm... on the picture it looks genuine, but you never know. Chinese copies can be very clever.
But I wonder about quality.
Could this be a QA reject?

manjh

Giving the "wifidisconnect" command will let the router/access point know that you (the unit) is going away from the network. Thus you will be sure that the network will greet the unit welcome once it returns online. If it is recommendable to do a WifiDisconnect before the reboot, then wh...

I decided to chicken-out and use the easy way... :oops: Wrote a small LUA script that checks the age of the value in the uptime device; if it is older than 1 minute (ESP sends value every 30 secs) and it is > 0, then I reset it to zero. Also at that point I write a single line to a logfile, with the...

a way to reduce the raw number of minutes I just divide %value%/60 and send it to Domoticz. To a virtual sensor Type: Custom Sensor, Axis label: hr.

You can also add the "Generic - System info" plugin and set it to "uptime". As it is a plugin, you can also send it to a controller and let it log in something like Domoticz, or whatever you use. Then you have a record on how often it reboots. Good idea, I put this in place for ...

After the reboot of the Netgear, can you see the uptime of the ESP nodes? I suspect they rebooted also. I had something similar last week. All nodes stopped sending data to Domoticz at the same time.

The sensors are working at 4.5V, that is confirmed. :) Regarding the "2 minutes to 90%" is in fact the response time for first "good" measure. The detector temperature need a certain time to reach a good level and after 2 minutes it has reached 90% of that level, at that point t...

Those CO2 sensors need quite a lot of current to work. So maybe a battery alone will not work for long because of the relative high internal resistance of the battery. I guess adding a big capacitor, with a resistor between capacitor and battery, may help here. Those super caps (0.47F, 5.5V) may be...

looks good. I will order a few and try this.

Great work Dave, this is useful. Even when using the non-corrosive version of the sensor, it makes sense.

To make the solution complete, I suggest two things:
1. add an electrical diagram
2. create a Wiki page with the full solution

Keep up the good work!

manjh

You could add that as feature request to our GitHub. I find the price plus communication protocol quite nice and see that more people would find it a good piece of hardware. There are even cheaper sensors available, but this one uses "capacitive measurement", which causes less corrosion. ...
