NAMF 47rc2 – new features

Today the binaries for the NAMF-47rc2 version (of course – in the beta update channel) hit the server. It brings quite significant new features. The first, which will be appreciated especially by those who have recuperation in their homes.

If you equip your NAM with the SDS011 restarter, then in the SDS configuration you can set the alarm to go off at a preset PM2.5 or PM10 value.

Then pin 7 (the one closest to the LED and SDS connector) will be set to high (3.3V) when alert value has been exceed. Remember that PCF used in restarter can drive only 400 µA in high state, so You need to use some transistor to drive any load.

If you have mechanical ventilation in the house, you can thus receive information about the need to turn it off when the air is of poor quality. Output this signal to the outside (don’t forget to also “take” GND from the EXT connector or any of the HX connectors) and you can control the device.

You can achieve a similar solution using home automation (whether Home Assistant or Domoticz), there are also ready-made commercial solutions. Here the advantage is simplicity – if you don’t have HA/Domoticz this will also work. Since it works locally, it doesn’t require access to the cloud as some of the solutions you’ll encounter from competitors have.

LoRaWAN

The NAM 0.4 kit, expected by some for a long time, has finally appeared – based on ESP32 and running on LoRaWAN. The kit is still in beta, but if anyone is strongly interested in testing – you are welcome. The NAMF-47rc2 version already allows you to use LoRaWAN – you just need to be in range of The Things Network. The other good news about TTN is that besides being in range you don’t need additional infrastructure – Tomek Rękawek, the author of aqi.eco has added an integration that allows you to send data from TTN to aqi.eco! But about the details, I will write on the Starter Kit, describing the configuration. For now, soldering instructions for the NAM 0.4 kit are available.

DNMS – measure noise

The next big news is support for DNMS! Digital Noise Measurement Sensor is, as the name suggests, a sensor that measures noise intensity. Well, and since version 47rc2 it is already supported by NAM.

To top it off – any day now a soldering kit will be on sale in our shop, which will allow you to build such a sensor

Reverse charge and orders

We have introduced new feature for our customers from EU, who order for companies. If data provided during checkout shows that order can be fulfilled with reverse charge for VAT:

  • delivery to EU country different than Poland
  • there will be an invoice for company outside of Poland

On last stage, just before placing an order our system will show request to check tax ID in VIES database. This is required step:

In case tax id is active in VIES database You will get notification:

After reloading page, You will get quote with VAT removed:

Different outcome will be in case VIES service does not work (happens quite often, since VIES is dependent on services from each EU country to validate tax IDs). In that case You will see something like that:

Then You can reload page and try again. Usually VIES disruption lasts only few minutes.

There can be other option – VIES is working and tax ID you have provided is not active. Usually that means You have provided different tax id (most countries have different tax ids for use when purchasing in other EU countries). Just correct invoice data and try again.

There can be also some formal reason that tax id is not recognized and reverse charge invoice can’t be issued. If You need reverse charge invoice then first resolve issue in tax office of country which have issued tax id.

Summary

In case You will validate your tax ID during checkout our system will charge you only amount without VAT. This is best way to pay for order with invoice.

If You won’t validate ID we will do it later and in case reverse charge invoice can be issued we will do it and refund VAT amount (this was how it was working until now). Be advised that charge via PayPal or PayU are in PLN (Polish złoty) and during refund your bank will do exchange. We can’t guarantee you will get exact refund in your currency.
