New gateway from Laird: Sentrius RG1XX

Where did you get your IP68 Enclosure?

(Myttndel) #154

were you able to get this working ?

(Jbkiwi) #155

Enclosure is a StationBox made by RF Elelments

(Jbkiwi) #156

Yep, got four out in the field and three more Raspberry Pi MTac based gateways as well.

Can you tell me about how many solar panels you used in this setup?

(Jeff Uk) #158

How many/size you will need will depend on placement - how much of a clear horizon you have, if there are buildings or trees obscuring /shadowing for part of day etc. - whether you have fixed or tracking install of the panels, and where you are in the world (solar elevation angle). The summer experiment kicked off with just one and a single battery per photo. It wasn’t expected that would be enough to get through winter :slight_smile: or even through Autumn days if weather poor. Have been experimenting with since and have also been evaluating 24hr pwr consumption of the target GW’s.

If it helps a crude measurement of the consumption for a Laird bd running off nominal 5V USB supply suggests ~8400mAh - assume reading was 10-20% ‘light’ and looks like 10,000mAh a good target 24Hr pwr spec to work with…

So you need one or more panels capable of powering GW whilst also charging the standby back-up battery and ensuring adequate reserves under local adverse conditions - leaf fall and snow cover etc. (unless you are in a desert of-course :wink: ), during whatever local sunshine hrs you get. During good summer weather I found I was getting useful (>75%MPP) for around 6-8 hrs/day so could size for ~1/3rd-1/4 of time being run with recovery whilst 2/3rd-3/4 draining battery. This time of year I’m finding its barely 1-2 hrs/day so have had to look at 50% increase in battery capacity and doubling up on the panels (Parallel install to ensure adequate charging current for battery whilst also running the GW). Even then I’m not convinced system will survive the worst a British winter and dark/rainy/snowy days can throw at it! Will be adjusting config as time goes on and will see what happens by time we get back to next spring :slight_smile:

I have just updated firmware of my RG186, after reboot all lights are blinking. What is the problem? How can I fix it?

And here is log of Laird from UART

@BWhitten Hi Ben can you shed light on this/recommend action or does @rserag need to go back through Laird support channels?

(Lachlan Etherton) #161

I must give credit where credit is due. The RG191 is a great gateway. For Aussies, they are one of easiest, most affordable and refined gateways on the market that work out the box for AU915. There is nothing at the same price point which works with such ease. They may have to have a firmware update done on them if they are older stock, but it beats mucking around with Raspberry Pis and he setup if all you want is a working gateway without the need for complete control and flexibility.

The best thing about this gateway is the fact that it works just like a modem router. It is not hard to setup, nor it is a new experience, it just does the job.

There is an issue with it however and it is the fact that when you access the web portal, it has a message saying “Connection with gateway may have been lost” which is annoying, but otherwise harmless. In addition, it is supplied with a US power supply, so those down under need to get a converter (female US to male AU) for about $10 to get it working.

Those interested can get them from Element14. Make sure it is the 915MHz version, otherwise it’ll be an expensive paper weight.


Thats had a partial upgrade, kernel and rootfs have gotten out of sync. This may have been due to an upgrade over unstable wifi or network outage.
It is unfortunatly an RMA job, later versions of the firmware dont suffer from this.

Thank you @BWhitten for support. @Jeff-UK thank you too!
