A customer approached us about the difference between SLB 9670VQ2.0 and SLB 9670XQ2.0.VQ has a standard temperature range of (-20 .. +85°C), and XQ is the enhanced temperature range version (-40 .. + 85°C).As the Raspberry Pi itself has a standard temperature range, we use the VQ version on the LetsTrust TPM.
It is possible to pass modifiers along with the “result”: “ok” return value of your webhook for VerneMQ.The official documentation of VerneMQ gives some examples for the syntax. changing the mountpointIt is also possible to change the mountpoint, however the client_id apparently has to be passed in as well!I have raised an issue with the [...]

Besides routing and redirecting you can serve static responses with Envoy.In this case I want to serve a forbidden response (403)route_config: virtual_hosts: - name: picockpit domains: ["picockpit.local:443", "picockpit.local"] routes: - match: { prefix: "/demo" } direct_response: status: 403 body: inline_string: "Forbidden." - match: {prefix: "/"} route: {cluster: target_picockpit}It can also serve up files from [...]
Using Paho in Python with websockets and self-signed certificates for a https:// websocket connection has a couple of pitfalls, so I’m addressing this with some sample code here:import ssl import time import paho.mqtt.client as mqtt class PCPMQTTClient: def on_connect(self, client, userdata, flags, rc): self.connection_status = rc if rc == 0: self.connected_flag = True self.connection_error_flag = [...]
