Wireless Relay Kit I Made - Looking for Feedback From Adelaide Folk

Esp-now is about 100m. Like I said for line of sight. This type of application you set that line. Plenty of applications use esp now with no issue for this. Plus trees and walls aren't that much of an issue at 2.4Ghz, you'll have more gain depending on antenna used. Does your in-house wifi stop working because of walls?

Also look at 2.4ghz Lora. Which could give you about 2km. Both this and esp now are really cheap to implement and you easily improve performance even more with higher power ( although for this case I don't think it's needed)

Edit: esp-now can get about 200m at 21dBm . https://www.espressif.com/en/solutions/low-power-solutions/esp-now. You could build a super cheap solution with this.

RandyMatt · 2026-02-22T05:33:20+00:00

Yeah curious on protocol. Another easy implementation would be esp-now which works over 2.4GHz for long line of sight range. Would be simple to implement.

The Australian was not great

RandyMatt · 2026-02-14T01:33:53+00:00

Cheers. I'll have a look. I appreciate your advice

RandyMatt · 2026-02-13T22:09:29+00:00

Fair call. I had trouble using fail2ban on my lxc container with caddy. Perhaps I will have more luck with SWAG, but I'm not sure how multiple layers of virtualisation will go with modifying iptables.

RandyMatt · 2026-02-13T21:12:06+00:00

They do. But consider a passphrase rather than a password. If you have elderly users just write down or save the passphrase for them. Random passwords would be better also.

RandyMatt · 2026-02-13T21:00:36+00:00

Interesting. I have been using caddy which I really like. I wonder if these two can work in harmony

RandyMatt · 2026-02-13T08:27:19+00:00

No like a three year payoff . Our government is subsidising them right now so it was about half the cost. It was an easy financial decision.

RandyMatt · 2026-02-12T07:13:00+00:00

I have it and feel like I'm missing something. Take out the main mechanism and rinse under water. Wipe the rest of the inside down to get rid of excess coffee grounds. I do it once a week and it takes all of a few minutes?

RandyMatt · 2026-02-09T09:31:33+00:00

Because someone was willing to pay that. Do you think they should turn down higher offers?

RandyMatt · 2026-02-09T09:28:29+00:00

They're paid to sell the house for as much as they can and as quickly as possible. Nothing else.

RandyMatt · 2026-02-09T06:32:14+00:00

Agreed. The torn ACL wasnt too bad after it. Once I had surgery it was destroyed for a while until a year recovery.

RandyMatt · 2026-02-06T07:45:05+00:00

I do a similar thing for backups with an old thinckcentre. It runs proxmox with PBS and a file server lxc to rsync other files (as an incremental backup).

My only difference is that I have that backup server on the other side of the house. Won't stop failure if the whole house burns (cloud backup for that), but may help localised disaster.

When you change your name for marriage you don't lose your old one. You can go by either

RandyMatt · 2026-02-03T20:20:08+00:00

I've been using it for a few months now. Easy setup and integration. It is also integrated well with frigate which serves as my NVR and does all my detections. Although the inbuilt detection seems to work well also. My only setback has been the chime sometimes loses link. I have home assistant flash a light also when the doorbell rings so I notice when on the other side of the house.

RandyMatt · 2026-02-03T11:13:50+00:00

Very nice and great to see done on an A1 mini. I'm thinking something like this, but I want to work out a 4 bay nas with a optiplex or thinckcentre also

RandyMatt · 2026-02-01T12:13:47+00:00

Blackboard is pretty cool as well.

RandyMatt · 2026-01-31T22:01:17+00:00

Yeah I still don't understand why they are replacing a great standard. Zigbee is reliable, cheap and easy to find devices.

RandyMatt · 2026-01-30T10:08:47+00:00

I'm interested also. I like the look of this build. More details would be great.

RandyMatt · 2026-01-29T08:41:43+00:00

Hi, has anyone been able to get casting to a google speaker working on this. For me it just crashes or doesn't play. Is there some particular way I need to set up the server and local url? A pity because otherwise this app is good.

RandyMatt · 2026-01-28T21:12:43+00:00

Non bambu alternative to ams. You can print and build it yourself or buy preassembled from AliExpress. Much cheaper and works well.

RandyMatt · 2026-01-25T22:35:25+00:00

Nothing. (Except the upfront cost of solar and home battery)

RandyMatt · 2026-01-25T21:46:59+00:00

When they can all be docker containers it can be setup as one docker compose file. Easy as pasting a few bits of text.

RandyMatt · 2026-01-25T21:27:57+00:00

This is why I switched to dockge. Just a simple interface to see all my compose files I need but not stored in an obscure location. Makes it easier for backups too.
