The problem now seems to be related to caching rules… So, some messing with that is required… My RB5009 is now stuck in France and has been there since Friday… It is scheduled for delivery on Wednesday, so that will be a fun day breaking stuff… Its been on quite the trip. Most of that was in 3 days, but it got stuck in France and hasnt moved over the weekend… Fingers crossed it arrives on Wednesday!https://www.tiernanotoole.ie/2022/08/30/bulk-updating-tasmota-devices-over-mqtt-100daysofhomelab.htmlTue, 30 Aug 2022 17:50:00 +0000https://www.tiernanotoole.ie/2022/08/30/bulk-updating-tasmota-devices-over-mqtt-100daysofhomelab.htmlI have a load of these Smart Plugs from GoSund around the house (currently around 11, but more are still in boxes). The handy part of these is they can be re-programmed using Tuya Convert and using the following config you can get power usage and an on/off switch. I have mine hooked up to an MQTT server, and with the MQTT plug-in to Home Assistant, I get all the details about power usage and can control each device I need to (hence the 11 of them!).https://www.tiernanotoole.ie/2022/03/16/raspberry-pi-in-a-car-part-2.htmlWed, 16 Mar 2022 19:37:36 +0000https://www.tiernanotoole.ie/2022/03/16/raspberry-pi-in-a-car-part-2.htmlFor the last few weeks, I have been running a Raspberry Pi in my car, along with a small UPS and a Wifi Access point, allowing me to download videos from my dash cam and back them up to my NAS in the house. But I have had some teething issues, and I am currently thinking my way through some fixes… While trying to figure out how to fix part 1, I came up with an idea: I have an older Mikrotik RB951G that can be powered via a 12v adapter for the car. I am going to use that, along with a Huawei 4G dongle to act as an internet connection. The onboard Wifi will be in client mode, so when it’s near the house, it will connect to the main network and send traffic through that to the internet (or internal NAS) and when away, use the LTE modem. Then, using the Wifi dongle on the Raspberry Pi, use that as a Wifi AP.https://www.tiernanotoole.ie/2022/02/25/running-a-raspberry-pi-in-a-car-and-backing-up-dashcam-footage.htmlThu, 24 Feb 2022 23:45:39 +0000https://www.tiernanotoole.ie/2022/02/25/running-a-raspberry-pi-in-a-car-and-backing-up-dashcam-footage.htmlA few months back (well, November 2020) I wrote about connecting to my car with Zerotier. In this post, I mentioned using a TP-Link router running OpenWRT and a Huawei LTE dongle to connect to the internet, which allowed me to then connect to my Blackvue Dashcam and watch remotely. But it had some issues I wanted to fix:https://www.tiernanotoole.ie/2020/11/09/connecting-to-my-car-over-zerotier.htmlMon, 09 Nov 2020 19:00:00 +0000https://www.tiernanotoole.ie/2020/11/09/connecting-to-my-car-over-zerotier.htmlI use ZeroTier on my network for a good few things, including internal network peering between BGP VMs, management of machines, and now, connecting to my car over LTE. This is one of those posts that sounds silly, but is very handy! First, the parts list: Car. 3G/4G/5G modem of some sort. I am using a Huawei Wingle. Can be used without the Router below, but I wanted Zerotier, so I have it in modem only mode. A router that supports Zerotier. I am using a modified TP-Link TL-WR703N upgraded to 16MB ROM and 64MB RAM. This is required for newer OpenWRT builds a dashcam that connects over Wifi. I am using a BlackVue DR750S-2CH Latest ROOter software from Of Modems and Men Patients. After installing the the latest copy of ROOter on the TPLink (or router of your choice) and getting the modem configured correctly (this took a while) you need to install the Zerotier software though the dashboard. Once installed, I joined my Zerotier network using the CLI (SSH into the router) and the approved it though the my.zerotier.com dashboard. Once its approved and connected, you can now go to the Zerotier IP and get to the router directly. From here, you can either setup a route in Zerotier to point at the internal network behind the router, or, in my case, setup a SSH tunnel to the dashcam. I found the IP given to the dashcam and used SSH forwarding to get to it. Finally, i used the URLs from Digital-Nebula’s hackview repo to get to the different URLs. I use this to download stuff like GPS logs, emergency videos, etc. I have to clean up some scripts at some stage for this, and plan to upload them at some stage.
