I recently switched to HA for my RESI9 PowerTags once I realised the Wiser system require cloud connection to see any data. The tags themselves communicate with the wiser hub over zigbee, but the app needs a cloud connection, fail!
Anyways, here is how I got the tags added and reporting energy:
My tags are all RESI9 tags with 1 or 3 phases that fit on SE RESI9 breakers. The single phase tags have a blue neutral lead, otherwise there are no external leads on them. I assume the generic ones for any type of breaker also work fine but have not tested.
Preparation:
- I got a Sonoff Zigbee 3.0 USB Dongle Plus. This MUST be the slightly larger P version, NOT the E version. The E version wont even pair the tags.
- I installed zigbee2mqtt and the mosquitto broker with the default settings.
- I added a IKEA range extender and placed it close to where I have the tags, this is the version wiht a usb port you can detach from its power plug. You can probably use any device that support zigbee green power and has Endpoint 242 > Output clusters > greenPower under the Clusters tab of the device. The IKEA one worked for me and is fairly cheap and available.
Pairing:
- Its very important to not allow anything to pair by default in zigbee2mqtt, once you connect the tags to power they enter pairing mode immediately and if they pair through the wrong device, they wont pair correctly.
- In the devices view of zigbee2mqtt, use the permit join dropdown and select the IKEA range extender and then click it to allow devices to join through that one only.
- After a few moments your tag should join. If it doesnt, make sure its blinking orange and also try disabling join and permit again on the IKEA range extender if it doesnt join immediately.
- Wait a couple of minutes and make sure the tag reports more then just signal strength under the “exposes” tab.
- If the tag only report signal strength, chances are it joined through the coordinator or another router.
Issues:
The 3 phase tags dont report any energy or power on the separate a, b, and c phases, only the total. The individual phases are all null. This was a bit of a bummer for me as I had hoped to split up the stove(2 phases) and oven (1 phase) in separate meters. I suppose I could use 3 single meters instead, but only the total is fine for now.
Interestingly enough, the single phase meters do report power and energy on the a port in addition to the total.
Its also a bit of a pain to remove them form the network if you make a mistake in the pairing, they dont completely unpair, but if you turn them off for a while, and also retart HA (and pray to moloch), they eventually reset and enter pairing mode again.
Hope someone is helped by this, I was very glad when I finally got them working as it allow me to get rid of the Wiser cloud bollocks.
