HBMQTT Overload Or Not?

Hi Guys’n’Gals,

I’ve seen a number of threads where people say that switching from the embedded MQTT broker to Mosquitto helped their system with memory and CPU usage and made it much more responsive.

What’s your experience in terms of number of devices where the troubles start?

I have two Sonoff S31 and two Aqara temperature sensors (via the zigbee2mqtt gateway) as well as two Wemos D1 Minis (one for the garage door opener and one for the drip system) and one door sensor (via Z-Wave).

I’ve started seeing issues with connectivity, i.e. values showing up as unknown in my frontend, but seven units can’t be the limit already, right?
